1 GNU GENERAL PUBLIC LICENSE
****************************

                         Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.  675
Mass Ave, Boston, MA 02111-1307, USA

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

Preamble
========

The licenses for most software are designed to take away your freedom
to share and change it.  By contrast, the GNU General Public License is
intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to
your programs, too.

When we speak of free software, we are referring to freedom, not price.
Our General Public Licenses are designed to make sure that you have the
freedom to distribute copies of free software (and charge for this
service if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid anyone
to deny you these rights or to ask you to surrender the rights.  These
restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether gratis
or for a fee, you must give the recipients all the rights that you
have.  You must make sure that they, too, receive or can get the source
code.  And you must show them these terms so they know their rights.

We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

Finally, any free program is threatened constantly by software patents.
We wish to avoid the danger that redistributors of a free program will
individually obtain patent licenses, in effect making the program
proprietary.  To prevent this, we have made it clear that any patent
must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and
modification follow.

    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  0. This License applies to any program or other work which contains a
     notice placed by the copyright holder saying it may be distributed
     under the terms of this General Public License.  The "Program",
     below, refers to any such program or work, and a "work based on
     the Program" means either the Program or any derivative work under
     copyright law: that is to say, a work containing the Program or a
     portion of it, either verbatim or with modifications and/or
     translated into another language.  (Hereinafter, translation is
     included without limitation in the term "modification".)  Each
     licensee is addressed as "you".

     Activities other than copying, distribution and modification are
     not covered by this License; they are outside its scope.  The act
     of running the Program is not restricted, and the output from the
     Program is covered only if its contents constitute a work based on
     the Program (independent of having been made by running the
     Program).  Whether that is true depends on what the Program does.

  1. You may copy and distribute verbatim copies of the Program's
     source code as you receive it, in any medium, provided that you
     conspicuously and appropriately publish on each copy an appropriate
     copyright notice and disclaimer of warranty; keep intact all the
     notices that refer to this License and to the absence of any
     warranty; and give any other recipients of the Program a copy of
     this License along with the Program.

     You may charge a fee for the physical act of transferring a copy,
     and you may at your option offer warranty protection in exchange
     for a fee.

  2. You may modify your copy or copies of the Program or any portion
     of it, thus forming a work based on the Program, and copy and
     distribute such modifications or work under the terms of Section 1
     above, provided that you also meet all of these conditions:

       a. You must cause the modified files to carry prominent notices
          stating that you changed the files and the date of any change.

       b. You must cause any work that you distribute or publish, that
          in whole or in part contains or is derived from the Program
          or any part thereof, to be licensed as a whole at no charge
          to all third parties under the terms of this License.

       c. If the modified program normally reads commands interactively
          when run, you must cause it, when started running for such
          interactive use in the most ordinary way, to print or display
          an announcement including an appropriate copyright notice and
          a notice that there is no warranty (or else, saying that you
          provide a warranty) and that users may redistribute the
          program under these conditions, and telling the user how to
          view a copy of this License.  (Exception: if the Program
          itself is interactive but does not normally print such an
          announcement, your work based on the Program is not required
          to print an announcement.)

     These requirements apply to the modified work as a whole.  If
     identifiable sections of that work are not derived from the
     Program, and can be reasonably considered independent and separate
     works in themselves, then this License, and its terms, do not
     apply to those sections when you distribute them as separate
     works.  But when you distribute the same sections as part of a
     whole which is a work based on the Program, the distribution of
     the whole must be on the terms of this License, whose permissions
     for other licensees extend to the entire whole, and thus to each
     and every part regardless of who wrote it.

     Thus, it is not the intent of this section to claim rights or
     contest your rights to work written entirely by you; rather, the
     intent is to exercise the right to control the distribution of
     derivative or collective works based on the Program.

     In addition, mere aggregation of another work not based on the
     Program with the Program (or with a work based on the Program) on
     a volume of a storage or distribution medium does not bring the
     other work under the scope of this License.

  3. You may copy and distribute the Program (or a work based on it,
     under Section 2) in object code or executable form under the terms
     of Sections 1 and 2 above provided that you also do one of the
     following:

       a. Accompany it with the complete corresponding machine-readable
          source code, which must be distributed under the terms of
          Sections 1 and 2 above on a medium customarily used for
          software interchange; or,

       b. Accompany it with a written offer, valid for at least three
          years, to give any third party, for a charge no more than your
          cost of physically performing source distribution, a complete
          machine-readable copy of the corresponding source code, to be
          distributed under the terms of Sections 1 and 2 above on a
          medium customarily used for software interchange; or,

       c. Accompany it with the information you received as to the offer
          to distribute corresponding source code.  (This alternative is
          allowed only for noncommercial distribution and only if you
          received the program in object code or executable form with
          such an offer, in accord with Subsection b above.)

     The source code for a work means the preferred form of the work for
     making modifications to it.  For an executable work, complete
     source code means all the source code for all modules it contains,
     plus any associated interface definition files, plus the scripts
     used to control compilation and installation of the executable.
     However, as a special exception, the source code distributed need
     not include anything that is normally distributed (in either
     source or binary form) with the major components (compiler,
     kernel, and so on) of the operating system on which the executable
     runs, unless that component itself accompanies the executable.

     If distribution of executable or object code is made by offering
     access to copy from a designated place, then offering equivalent
     access to copy the source code from the same place counts as
     distribution of the source code, even though third parties are not
     compelled to copy the source along with the object code.

  4. You may not copy, modify, sublicense, or distribute the Program
     except as expressly provided under this License.  Any attempt
     otherwise to copy, modify, sublicense or distribute the Program is
     void, and will automatically terminate your rights under this
     License.  However, parties who have received copies, or rights,
     from you under this License will not have their licenses
     terminated so long as such parties remain in full compliance.

  5. You are not required to accept this License, since you have not
     signed it.  However, nothing else grants you permission to modify
     or distribute the Program or its derivative works.  These actions
     are prohibited by law if you do not accept this License.
     Therefore, by modifying or distributing the Program (or any work
     based on the Program), you indicate your acceptance of this
     License to do so, and all its terms and conditions for copying,
     distributing or modifying the Program or works based on it.

  6. Each time you redistribute the Program (or any work based on the
     Program), the recipient automatically receives a license from the
     original licensor to copy, distribute or modify the Program
     subject to these terms and conditions.  You may not impose any
     further restrictions on the recipients' exercise of the rights
     granted herein.  You are not responsible for enforcing compliance
     by third parties to this License.

  7. If, as a consequence of a court judgment or allegation of patent
     infringement or for any other reason (not limited to patent
     issues), conditions are imposed on you (whether by court order,
     agreement or otherwise) that contradict the conditions of this
     License, they do not excuse you from the conditions of this
     License.  If you cannot distribute so as to satisfy simultaneously
     your obligations under this License and any other pertinent
     obligations, then as a consequence you may not distribute the
     Program at all.  For example, if a patent license would not permit
     royalty-free redistribution of the Program by all those who
     receive copies directly or indirectly through you, then the only
     way you could satisfy both it and this License would be to refrain
     entirely from distribution of the Program.

     If any portion of this section is held invalid or unenforceable
     under any particular circumstance, the balance of the section is
     intended to apply and the section as a whole is intended to apply
     in other circumstances.

     It is not the purpose of this section to induce you to infringe any
     patents or other property right claims or to contest validity of
     any such claims; this section has the sole purpose of protecting
     the integrity of the free software distribution system, which is
     implemented by public license practices.  Many people have made
     generous contributions to the wide range of software distributed
     through that system in reliance on consistent application of that
     system; it is up to the author/donor to decide if he or she is
     willing to distribute software through any other system and a
     licensee cannot impose that choice.

     This section is intended to make thoroughly clear what is believed
     to be a consequence of the rest of this License.

  8. If the distribution and/or use of the Program is restricted in
     certain countries either by patents or by copyrighted interfaces,
     the original copyright holder who places the Program under this
     License may add an explicit geographical distribution limitation
     excluding those countries, so that distribution is permitted only
     in or among countries not thus excluded.  In such case, this
     License incorporates the limitation as if written in the body of
     this License.

  9. The Free Software Foundation may publish revised and/or new
     versions of the General Public License from time to time.  Such
     new versions will be similar in spirit to the present version, but
     may differ in detail to address new problems or concerns.

     Each version is given a distinguishing version number.  If the
     Program specifies a version number of this License which applies
     to it and "any later version", you have the option of following
     the terms and conditions either of that version or of any later
     version published by the Free Software Foundation.  If the Program
     does not specify a version number of this License, you may choose
     any version ever published by the Free Software Foundation.

 10. If you wish to incorporate parts of the Program into other free
     programs whose distribution conditions are different, write to the
     author to ask for permission.  For software which is copyrighted
     by the Free Software Foundation, write to the Free Software
     Foundation; we sometimes make exceptions for this.  Our decision
     will be guided by the two goals of preserving the free status of
     all derivatives of our free software and of promoting the sharing
     and reuse of software generally.

                                NO WARRANTY
 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
     WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
     LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
     HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
     WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
     NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
     FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE
     QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
     PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
     SERVICING, REPAIR OR CORRECTION.

 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
     MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
     LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
     INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
     INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
     OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
     OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
     ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

                      END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
=============================================

If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.

To do so, attach the following notices to the program.  It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

ONE LINE TO GIVE THE PROGRAM'S NAME AND AN IDEA OF WHAT IT DOES.
Copyright (C) 19YY  NAME OF AUTHOR

This program is free software; you can redistribute it and/or
modify it under the terms of the GNU General Public License
as published by the Free Software Foundation; either version 2
of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
GNU General Public License for more details.

You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) 19YY NAME OF AUTHOR
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w'.  This is free software, and you are welcome
to redistribute it under certain conditions; type `show c'
for details.

The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License.  Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright
interest in the program `Gnomovision'
(which makes passes at compilers) written
by James Hacker.

SIGNATURE OF TY COON, 1 April 1989
Ty Coon, President of Vice

This General Public License does not permit incorporating your program
into proprietary programs.  If your program is a subroutine library,
you may consider it more useful to permit linking proprietary
applications with the library.  If this is what you want to do, use the
GNU Library General Public License instead of this License.

2 About VICE
************

VICE is the one and only "Versatile Commodore Emulator".  It provides
emulation of the Commodore C64, C64DTV, C128, VIC20, PET, PLUS4 and
CBM-II computers within a single package.  The emulators run as
separate programs, but have the same user interface, share the same
settings and support the same file formats.

*Important notice:* If you have no idea what a Commodore 8-bit computer
is, or have questions about how these machines are used, how the file
formats work or anything else that is not strictly related to VICE, you
should read the appropriate FAQs _first_, as that kind of information
is not available here.  *Note Contacts::. for information about how to
retrieve the FAQs.

All the emulators provide an accurate 6502/6510 emulator, with emulation
of all the opcodes (both documented and undocumented ones) and accurate
timing.  Unlike other emulators, VICE aims to be cycle accurate; it
tries to emulate chip timings as precisely as possible and does so
_efficiently_.

Please do _not_ expect the C64DTV, C128, PET, PLUS4 and CBM-II
emulators to be as good as the C64 or VIC20 one, as they are still
under construction.

_Notice:_ This documentation is written for the Unix release of VICE.

2.1 C64 emulator features
=========================

As of version 2.3, two C64 emulators are provided: `x64' (fast) and
`x64sc' (accurate).

The fast C64 emulator, called `x64', features a fairly complete
emulation of the VIC-II video chip: sprites, all registers and all video
modes are fully emulated.  The emulation has been fully cycle-accurate
since version 0.13.0.

The accurate C64 emulator, called `x64sc', features a cycle-based and
pixel-accurate VIC-II emulation. This requires a much faster machine
than the old `x64'.

A rather complete emulation of the SID sound chip is also provided.  All
the basic features are implemented as well as most of the complex ones
including synchronisation, ring modulation and filters.  There are three
emulators of the SID chip available: first is the "standard" VICE
emulator, available since VICE 0.12; the second is Dag Lem's reSID
engine and the third one is reSID-fp. The reSID engines are a lot more
accurate than the standard engine, but they are also a lot slower, and
only suitable for faster machines.

Naturally, also both CIAs (or VIAs, in some cases) are fully emulated
and cycle accurate.

2.2 C64DTV emulator features
============================

The C64DTV emulator, called `x64dtv', features emulation of C64DTV
revisions 2 and 3. The emulator is under construction, but most of the
DTV specific features are already supported (with varying accuracy).

Video cache is disabled by default as it currently doesn't work with
some of C64DTV's new video modes. The new video modes have a simple
"fake" video cache implementation that may give incorrect results and
decreased performance.

2.3 C128 emulator features
==========================

The C128 emulator, called `x128', features a complete emulation of the
internal MMU ("Memory Management Unit"), 80 column VDC screen, fast IEC
bus emulation, 2 MHz mode, Z80 emulation plus all the features of the
C64 emulation.


File: vice.info,  Node: VIC20 emulator features,  Next: PET emulator features,  Prev: C128 emulator features,  Up: Preface

2.4 VIC20 emulator features
===========================

The VIC20 emulates all the internal hardware, including the VIA chips.
The VIC-I video chip is fully emulated except NTSC interlace mode, so
most graphical effects will work correctly.

Sound support is implemented, but is still at an experimental stage.  If
you think it could be improved and know how to do so, feel free to
contact us (*note Contacts::).

The VIC20 emulator now allows the use of the VIC1112 IEEE488 interface.
You have to enable the hardware (by menu, resource, or commandline
option) and then load the IEEE488 ROM (see for example
`http://www.funet.fi/pub/cbm/schematics/cartridges/vic20/ieee-488/325329-04.bin',
but you have to double the size to 4k for now).  The IEEE-488 code is
then started by `SYS45065'.


File: vice.info,  Node: PET emulator features,  Next: CBM-II emulator features,  Prev: VIC20 emulator features,  Up: Preface

2.5 PET emulator features
=========================

The PET emulator emulates the 2001, 3032, 4032, 8032, 8096, 8296 and
SuperPET (MicroMainFrame 9000) models, covering practically the whole
series.  The hardware is pretty much the same in each and that is why
one single program is enough to emulate all of them.  For more detailed
information about PET hardware please refer to the `PETdoc' file.

Both the 40 column and 80 column CRTC video chips are emulated (from the
4032 onward), but a few of the features are not implemented yet (numbers
of rasterlines per char and lines per screen).  Fortunately, they are
not very important for average applications.

Sound is available for the PET as well, but like the VIC20's it is still
under construction.

The PET 8096 is basically a PET 8032 with a 64k extension board which
allows remapping the upper 32k with RAM.  You have to write to a special
register at `$fff0' to remap the memory.  The PET 8296 is a 8096 but
with a completely redesigned motherboard with 128k RAM in total.  Of
the additional 32k RAM you can use only some in blocks of 4k, but you
have to set jumpers on the motherboard for it.  VICE uses the command
line options `-petram9' and `-petramA' instead.  Also, the video
controller can handle a larger address range.  The PET 8x96 model
emulations run the Commodore LOS-96 operating system - basically an
improved BASIC 4 version with up to 32k for BASIC text and 32k for
variables.  See `PETdoc' for more information.

The SuperPET also is a PET 8032 with an expansion board.  It can map 4k
at a time out of 64k into the `$9***' area.  Also it has an ACIA 6551
for RS232 communication.  The 6809 CPU that is built into the SuperPET
is now emulated, since release 2.4, including the 6702 dongle chip.

The PET computers came with three major ROM revisions, so-called BASIC
1, 2 and 4, all of which are provided.  The PET 2001 uses the version 1,
the PET 3032 uses version 2, and the others use version 4.  The 2001 ROM
is horribly broken with respect to IEEE488 (they shipped it before they
tested it with the floppy drive, so only tape worked.  Therefore the
emulator patches the ROM to fix the IEEE488 routines.

As well as other low-level fixes the 2001 patch obtains the load address
for a program file from the first two bytes of the file.  This allows
the loading of both PET2001-saved files (that have $0400 as their load
address) and other PET files (that have $0401).  The PET2001 saves from
$0400 and not from $0401 as other PETs do.

Moreover, the secondary addresses used are now `0' and `1' for load and
save, respectively, and not arbitrary unused secondary addresses.

To select which model to run, specify it on the command line with the
`-model MODEL' option, where `MODEL' can be one of a list of PET model
numbers, all described in *note PET model::

2.6 CBM-II emulator features
============================

The CBM-II emulator emulates several types of CBM-II models.  Those
models are known under different names in the USA and Europe.  In the
States they have been sold as `B128' and `B256', in Europe as `CBM
610', `CBM 620' (low-profile case) or `CBM 710' and `CBM 720'
(high-profile case with monitor). In addition to that now an
experimental C510 emulation is included. The C510 (also known as P500)
is the little brother of the C600/700 machines. It runs at roughly 1
MHz and, surprise, it has a VIC-II instead of the CRTC. Otherwise the
different line of computers are very similar.

These computers are prepared to take a coprocessor board with an 8088 or
Z80 CPU.  Indeed there are models `CBM 630' and `CBM 730' that
supposedly had those processors.  However these models are not emulated.

The basic difference is the amount of RAM these machines have been
supplied with.  The `B128' and the `CBM *10' models had 128k RAM, the
others 256k. This implies some banking scheme, as the 6502 can only
address 64k.  And indeed those machines use a 6509, that can address 1
MByte of RAM.  It has 2 registers at addresses 0 and 1.  The indirect
bank register at address 1 determines the bank (0-15) where the opcodes
`LDA (zp),Y' and `STA (zp),Y' take the data from.  The exec bank
register at address 0 determines the bank where all other read and
write addresses take place.

The business line machines (C6xx/7xx) have the RAM in banks 1-2, resp.
1-4. All available banks are used for BASIC, where program code is
separated from all variables, resp. from normal variables, strings and
arrays that are distributed over other banks. The C510 instead has RAM
in banks 0 and 1, and uses bank 1 for program and all variables. Bank
0, though, can be accessed by the VIC-II to display graphics.

Many models have been expanded to more than the built-in memory.  In
fact some machines have been expanded to the full 1M.  Bank 15 is used
as system bank, with only little RAM, and lots of expansion cartridge
ROM area, the I/O and the kernal/basic ROMs.  Some models have been
modified to map RAM into the expansion ROM area.  Those modifications
can be emulated as well.

The different settings are described in *note CBM-II model::.

2.7 The keyboard emulation
==========================

There are two ways of emulating the keyboard in VICE.

The default way ("symbolic mapping") is to map every key combination to
the corresponding key combination on the real machine: for example, if
you press <*>, which is bound to `Shift-8' on a U.S. keyboard, in the
C64 emulator, the emulated machine will have just the _unshifted_ <*>
key pressed (as <*> is unshifted on the C64 keyboard).  Likewise,
pressing <'> on the same U.S. keyboard without any shift key will cause
the combination `Shift-7' to be pressed in the emulated C64.  This way,
it becomes quite obvious what keys should be typed to obtain all the
symbols.

There is, however, one problem with symbolic mapping: some keys really
need to be mapped specially regardless.  The most important examples
being, in the VIC20, C64 and C128 emulators, that <CTRL> is mapped to
<Tab> and that the <Commodore> key is mapped to the left <Control>).
The <RUN/STOP> key is mapped to the <ESC> key on the PC keyboard. The
PET emulator, lacking the <Commodore> key but having an <ESC> key, uses
the left <Control> key as <RUN/STOP> and the <ESC> key as <ESC> of
course.

The second way ("positional mapping") is to map every key on the "real"
keyboard to the key which has the same position on the keyboard of the
emulated machine.  This way, no <Shift> key is forced by the program
(with the exception of the function keys <F2>, <F4>, <F6> and <F8>,
which require <Shift> on the Commodore keyboards), and the keyboard is
more comfortable to use in those programs (such as some games) that
require the keys to be in the correct positions.

*Warning:* unlike the real C64, VICE "presses" the <Shift> key
_together_ with the key to shift when the <Shift> must be forced.  In
most cases this should work fine, but some keyboard routines are quite
picky and tend not to recognize the shift key because of this.  For
instance, `F6' (which on the real C64 is obtained with `Shift + F5')
could be recognized as `F5'.  In that case, use the shift key manually
(i.e., type `Shift + F5' in the example).  Yes, we know this is a bug.

The `RESTORE' key is mapped to `Page Up' (or `Prev') by default.

2.8 The joystick emulation
==========================

Joysticks can be emulated both via the keyboard and via a real joystick
connected to the host machine (the latter only works on GNU/Linux
systems).

There are two keyboard layouts for joystick use, known as "numpad" and
"custom".

The "numpad" layout uses the numeric keypad keys, i.e., the numbers
<1>...<9> which emulate all the directions including the diagonal ones;
<0> emulates the fire button.

The "custom" layout uses the keys <w>, <e>, <r>, <s>, <d>, <f>, <x>,
<c>, <v> for the directions and <space> for the fire button instead.


File: vice.info,  Node: Disk drive emulation,  Next: Supported file formats,  Prev: Joystick emulation,  Up: Preface

2.9 The disk drive emulation
============================

All the emulators support up to 4 external disk drives as devices 8, 9,
10 and 11.  Each of these devices can emulate virtual Commodore 1541,
1541-II, 1571, 1581, 2031, 2040, 3040, 4040, 1001, 8050 and 8250 drives
in one of four ways:

   * using disk images, i.e., files that contain a dump of all the
     blocks contained in a real floppy disk (if you want more
     information about what a disk image is, consult the
     `comp.emulators.cbm' FAQ);

   * accessing file system directories, thus giving you the use of files
     without having to copy them to disk images; this also allows you to
     read and write files in the `P00' format (again, consult the
     `comp.emulators.cbm' FAQ for more info).

   * accessing a real device connected to the host machine. As of VICE
     1.11 it is possible to connect real drives like Commodore 1541 to
     the printer port of the host using the XA1541 or XM1541 cable.
     Currently this only works on Linux or Windows using the OpenCBM
     library. You can get it from
     http://www.lb.shuttle.de/puffin/cbm4linux (cbm4linux, Linux
     version) or from http://cbm4win.sf.net/ (cbm4win, Windows version).

   * directly using the disk drive of the host. The 3.5" disk drive of
     the host can be used to read or write Commodore 1581 formatted
     disks.  Currently this raw drive access feature is only available
     for Linux hosts.

When using disk images there are two available types of drive
emulation.  One of them the "virtual drive" emulation.  It does _not_
really emulate the serial line, but patches the kernal ROM (with the
so-called "kernal traps") so that serial line operations can be
emulated via C language routines.  This emulation is very fast, but
only allows use of standard DOS functions (and not even all of them).
For real device or raw drive access it is required to enable this type
of emulation.

The IEEE488 drives (2031, 2040, 3040, 4040, 1001, 8050 and 8250) do not
use kernal traps. Instead the IEEE488 interface lines are monitored and
the data is passed to the drive emulation. To use them on the C64, you
need to enable the IEEE488 interface emulation. Only if the IEEE488
emulation is enabled, those drives can be selected.

The other alternative is a "true drive" emulation.  The Commodore disk
drives are provided with their own CPU (a 6502 as the VIC20 and the
PETs) and their own RAM and ROM.  So, in order to more closely emulate
its features, a complete emulation of this hardware must be provided
and that is what the "hardware level" emulation does. When the
"hardware level" emulation is used, the kernal routines are remain
unpatched and the serial line is fully emulated.  The problem with this
emulation is that it needs a lot of processing power, mainly because
the emulator has to emulate two CPUs instead of one.

The PETs do not use a serial IEC bus to communicate with the floppy
drive but instead use the parallel IEEE488 bus.  This does _byte by
byte_ transfers, as opposed to the _bit by bit_ transfers of the C64
and VIC20, so making it feasible to emulate the parallel line
completely while emulating the drive at DOS level only.  The IEEE488
line interpreter maps the drives 8-11 (as described above) to the
IEEE488 disk units, and no kernal traps are needed.  The same emulation
of the Commodore IEEE488 bus interface is available for the C64 and the
VIC20. With IEEE488 drives you can have true 2031 emulation at unit #8,
and still have filesystem access at units #10 or #11, because
monitoring the IEEE488 lines does not interfere with the true drive
emulation.

The IEEE488 disk drives 2040, 3040, 4040, 8050 and 8250 are Dual Drive
Floppy Disks.  This means that these drives handle two disks. To
accomplish the emulation, only two disks can be emulated, namely units
#8 and #10. The attached image, track display and LED display of unit
#9 and #11 are used for the second drive of the dual disk drives. On
unix the unit number display (8 or 9, 10 or 11) in the emulation window
changes to the drive number display (0 or 1).

The Commodore 2040, 3040, 4040, 1001, 8050 and 8250 disk drives are
so-called "old-style" disk drives. Their architecture includes not one,
but two processors of the 6502 type, namely a 6502 for the file
handling and communication with the PET (IP), and a 6504 (which is a
6502 with reduced address space) for the drive handling (FDC). Both
processors communicate over a shared memory area. The IP writes
commands to read/write blocks to this area and the FDC executes them.
To make the emulation feasible, the FDC processor is not emulated
cycle-exactly as a 6504, but simply by checking the commands and
executing them on the host. This provides a fast FDC emulation, but
disallows the sending the FDC processor commands to execute code.
Applications where this is necessary are believed to be rather seldom.
Only the format command uses this feature, but this is checked for.

The dual disk drive 2040 emulates one of the very first CBM disk
drives. This drive has DOS version 1. DOS1 uses an own disk type, that
is closely related to the 1541 disk image. Only on tracks 18-24 DOS1
disks have a sector more than 1541 disks. DOS1 disk images have the
extension .d67.

The dual disk drives 3040 and 4040 use the same logical disk format as
the VC1541 and the 2031. In fact, the 4040 was the first disk with DOS
version 2. The 3040 emulated here originally was the same as 2040, only
for the european 30xx PET series. As many of the original DOS1 disk
drives were upgraded (a simple ROM upgrade!) to DOS2, I use the 3040
number for a DOS 2.0 disk drive, and 4040 for a revised DOS 2 disk
drive. It is, however, not yet clear whether the disks here are write
compatible to the 1541, as rumors exist that the write gap between
sectors is different. But read compatible they are. As VICE emulates
the FDC processor in C and not as 6504 emulation, this does not matter
in VICE.

The drives 1001, 8050 and 8250 do actually have the very same DOS ROM.
Only the code in the FDC is different, which is taken care of by VICE.
So for all three of those disk drives, only `dos1001' is needed. The
DOS version used is 2.7.

2.10 Supported file formats
===========================

VICE supports the most popular Commodore file formats:

   * `X64' (preferred) or `D64' disk image files; Used by the 1541,
     2031, 3040, 4040 drives.

   * `G64' GCR-encoded 1541 disk image files

   * `P64' NRZI flux pulse disk image files

   * `D67' CBM2040 (DOS1) disk image format

   * `D71' VC1571 disk image format

   * `D81' VC1581 disk image format

   * `D80' CBM8050 disk image format

   * `D82' CBM8250/1001 disk image format

   * `D1M' FD2000/FD4000 DD disk image format

   * `D2M' FD2000/FD4000 HD disk image format

   * `D4M' FD4000 ED disk image format

   * `T64' tape image files (read-only)

   * `P00' program files

   * `CRT' C64 cartridge image files


An utility (`c1541', *note c1541::) is provided to allow transfers and
conversions between these formats.

Notice that the use of the `X64' file format is depreciated now.

You can convert an `X64' file back into a `D64' file with the UNIX `dd'
command:

dd bs=64 skip=1 if=IMAGE.X64 of=IMAGE.D64

formats.

2.11 Common problems
====================

This section tries to describe the most common known problems with VICE,
and how to resolve them.

* Menu:

* Sound problems::
* Shared memory problems::
* Printer problems::
* PET keyboard problems::


File: vice.info,  Node: Sound problems,  Next: Shared memory problems,  Prev: Common problems,  Up: Common problems

2.11.1 Sound problems
---------------------

VICE should compile and run without major problems on many UNIX systems,
but there are some known issues related to the sound driver.  In fact,
the sound code is the least portable part of the emulator and has not
yet been thoroughly tested on all the supported platforms.

Linux, AIX and SGI systems should play sound without any problems; if
you are running Linux please use a 2.x kernel, as VICE needs some
features that were not implemented in older versions of the Linux sound
driver.

On the other hand, HP-UX and Solaris machines are known to cause
troubles.  If you think you can help debugging the code for these
systems, your help would be really appreciated.  We are having troubles
finding HP-UX and SUN consoles to work at...

Some problems have been reported with the proprietary version of the
Open Sound System for Linux.  With a Crystal sound card, sound output
was significantly delayed and, apparently, the allocated buffer size was
completely wrong.  This is not a VICE bug, but rather an OSS bug.


File: vice.info,  Node: Shared memory problems,  Next: Printer problems,  Prev: Sound problems,  Up: Common problems

2.11.2 Shared memory problems
-----------------------------

If you cannot start VICE because you get errors about shared memory, try
to run it with the `+mitshm' command-line option (*note Video
options::).  This will completely disable usage of the MITSHM
extensions, that are normally used to speed up the emulation window
updates.  Of course, this will also result in a big loss in speed.

Reasons for this failure could be:

   * IPC support has been disabled at the system level; some system
     administrators disable this for security reasons.  If _you_ are the
     system administrator, use a kernel that has IPC support compiled
     in and enabled.

   * You are attempting to run the emulator across the network (i.e.,
     the emulator runs on one machine, and the output is displayed on
     another machine that works as an X terminal) and for some reason
     VICE does not recognize this fact.  In this case, you have found a
     bug, so please report it to us.

If you want to avoid running the emulator with `+mitshm' every time,
run it once with `+mitshm' and then choose "Save settings" from the
right-button menu.


File: vice.info,  Node: Printer problems,  Next: PET keyboard problems,  Prev: Shared memory problems,  Up: Common problems

2.11.3 Printer problems
-----------------------

VICE supports the emulation of a printer either on the userport or as
IEC device 4. Unfortunately the Commodore IEC routines do not send all
commands to the IEC bus. For example an `OPEN 1,4' is not seen on the
IEC bus. Also a `CLOSE 1' after that is not seen. VICE can see from
printing that there was an `OPEN', but it cannot see when the close
was. Also a "finish print job" cannot be seen on the userport device.
To flush the printer buffer (write to `print.dump' or to the printer)
now a menu entry can be used. Disabling and re-enabling the printer
should work as well.

The printing services have not been extensively tested but apart from
the problem mentioned above it should work fine now.


File: vice.info,  Node: PET keyboard problems,  Prev: Printer problems,  Up: Common problems

2.11.4 PET keyboard problems
----------------------------

If you find that the German keyboard mapping (plus German charset) does
not print uppercase umlauts, then you are right.  The umlauts replace
the [,\ and ] characters in the charset. The keys that make these
characters do not have a different entry in the PET editor ROM tables
when shifted.  Thus it is not possible to get the uppercase umlauts in
the editor.  Nevertheless other programs are reported to change the
keyboard mapping table and thus allow the use of the shifted
(uppercase) umlauts.

Anyway, the VICE keyboard mappings are far from being perfect and we
are open to any suggestions.

3 Invoking the emulators
************************

The names of the available emulators are:

   * `vsid', the SID player

   * `x64', the fast C64 emulator

   * `x64sc', the accurate C64 emulator

   * `x64dtv', the C64DTV emulator

   * `x128', the C128 emulator

   * `xvic', the VIC20 emulator

   * `xpet', the PET emulator

   * `xplus4', the PLUS4 emulator

   * `xcbm2', the CBM-II emulator (CRTC models)

   * `xcbm5x0', the CBM-II emulator (VIC-II models)


You can run each of them by simply typing the name from a shell or by
configuring your window manager for example to use them to open disk
images.

If you want to look at the log output, or use the monitor in a port
which does not have a dedicated monitor UI yet (such as the XAW port),
you should always run them from a terminal window such as `xterm' or
`rxvt'.  For example, you could do

xterm -e x64

3.1 Command-line options used during initialization
===================================================

There are several options you can specify on the command line.  Some of
them are used to specify emulation settings and will be described in
detail later (*note Settings and resources:: for a complete list).  The
remaining options are used only to give usage information or to
initialize the emulator in some way:

`-help'
`-?'
     List all the available command-line options and their meaning.  

`-default'
     Set default resources (*note Settings and resources::).  This will
     override all the settings specified before, but not the settings
     specified afterwards on the command line.

`-logfile <name>'
     Specify log file name 

`-verbose'
     Enable verbose log output.  

`-keybuf <string>'
     Put the specified string into the keyboard buffer.  

`-console'
     Console mode (for music playback) 

`-chdir <directory>'
     Change the working directory.  

`-autostart IMAGE'
     Autostart `IMAGE' (*note Command-line autostart::).

File: vice.info,  Node: Command-line autostart,  Prev: Command-line initialization,  Up: Usage

3.2 Autostarting programs from the command-line
===============================================

It is possible to let the emulator "autostart" a disk or tape image
file, by simply specifying its name as the _last_ argument on the
command line, for example

x64 lovelygame.x64.gz

will start the C64 emulator, attaching `lovelygame.x64.gz' as a disk
image and running the first program on it.  You can also specify the
name of the program on the fisk image by appending a colon (`:') the
name itself to the argument; for example

x64 "lovelygame.x64.gz:run me"

will run the program named `run me' on `lovelygame.x64.gz' instead of
the first one.

Using the command-line option `-autostart' is equivalent; so the same
result can be obtained with

x64 -autostart "lovelygame.x64.gz:run me"

If you specify a raw CBM or P00 file, the emulator will setup the file
system based drive emulation so that it is enabled and accesses the
directory containing the file first.  This is a very convenient way to
start multi-file programs stored in file system directories and not
requiring "true" drive emulation.

*Note Disk and tape images::. for more information about images and
autostart.


File: vice.info,  Node: System files,  Next: Basics,  Prev: Usage,  Up: Top

4 System files
**************

In order to work properly, the emulators need to load a few system
files:

   * the "system ROMs", raw binary files containing copies of the
     original ROMs of the machine you are emulating;

   * the "keyboard maps", text files describing the keyboard layout;

   * the "palette files", text files describing the colors of the
     machine you are emulating.

   * the "romset files", text files describing the different ROMs to
     load.


The place where they will be searched for depends on the value of the
`Directory' resource, which is a colon (`:')-separated search path
list, like the UNIX `PATH' environment variable.  The default value is

PREFIX/lib/vice/EMU:$HOME/.vice/EMU:BOOTPATH/EMU

Where `PREFIX' is the installation prefix (usually `/usr/local'), `EMU'
is the name of the emulated machine (`C64', `C64DTV', `C128', `PET',
`PLUS4', `CBM-II' or `VIC20') and `BOOTPATH' is the directory where the
executable resides.  The disk drive ROMs are looked for in a directory
with `EMU' set to `DRIVES'. `$HOME' is the user's home directory.

For example, if you have the C64 emulator installed in

/usr/local/bin/x64

then the value will be

/usr/local/lib/vice/C64:$HOME/.vice/C64:/usr/local/bin/C64

And system files will be searched for under the following directories,
in the specified order:

  1. `/usr/local/lib/VICE/C64'

  2. `$HOME/.vice/C64'

  3. `/usr/local/bin/C64'

System files can still be installed in a different directory if you
specify a complete path instead of just a file name.  For example, if
you specify `./kernal' as the kernal image name, the kernal image will
be loaded from the current directory.  This can be done by using
command-line options or by modifying resource values (*note Resource
files::).

* Menu:

* ROM files::                   Files containing dumps of the original ROMs.

File: vice.info,  Node: ROM files,  Next: Keymap files,  Prev: System files,  Up: System files

4.1 ROM files
=============

Every emulator requires its own ROM set.  For the VIC20 and the C64, the
ROM set consists of the following files:

   * `kernal',  the Kernal ROM (8 KBytes)

   * `basic', the Basic ROM (8 KBytes)

   * `chargen', the character generator ROM (4 Kbytes)


The C128 needs the following files:

   * `kernal', the Kernal ROM (8 Kbytes)

   * `basic', the Basic + Editor ROM (32 Kbytes)

   * `chargen', the character generator ROM (4 Kbytes)


The C128, VIC20 and C64 emulators also need the following DOS ROMs for
the hardware-level emulation of the 1541, 1571, 1581, 2000 and 4000 disk
drives:

   * `dos1541', the 1541 drive ROM (16 Kbytes)

   * `dos1541II', the 1541-II drive ROM (16 Kbytes)

   * `dos1571', the 1571 drive ROM (32 Kbytes)

   * `dos1581', the 1581 drive ROM (32 Kbytes)

   * `dos2000', the 2000 drive ROM (32 Kbytes)

   * `dos4000', the 4000 drive ROM (32 Kbytes)


In addition to those all emulators can handle a parallel IEEE488
interface (the C64 and C128 via `$df**' extension, the VIC20 via
VIC1112 emulation) so they also need the DOS ROM for the IEEE disk
drives:

   * `dos2031', the 2031 drive ROM (16 Kbytes) (DOS 2.6, Commodore ROM
     images 901484-03 and 901484-05)

   * `dos2040', the 2040 drive ROM (8 Kbytes) (DOS 1, Commodore ROM
     images 901468-06, 901468-07)

   * `dos3040', the 3040 drive ROM (12 Kbytes) (DOS 2, Commodore ROM
     images 901468-11, 901468-12 and 901468-13)

   * `dos4040', the 4040 drive ROM (12 Kbytes) (DOS 2, Commodore ROM
     images 901468-14, 901468-15 and 901468-16)

   * `dos1001', the 1001/8050/8250 drive ROM (16 Kbytes) (DOS 2.7,
     Commodore ROM images 901887-01 and 901888-01)


Note that there are other DOS images on the internet. The DOS 2.5 images
might be used with the 8050, but it cannot handle the double sided
drives of the 1001 and 8250 and it is not supported by VICE.

The PET emulator uses an expanded setup, because there are three major
versions of the Basic and the Kernal, and many versions of the Editor
ROM. In addition there are cartridge ROM sockets.

The Kernal files contain the memory from range $F000-$FFFF, the Basic
ROMs either the range $C000-$DFFF or $B000-$DFFF.  To handle the
different screen sizes and keyboards, different so-called "editor-ROMs"
for the memory range $E000-$E800 are provided.  The PET ROMs have the
following names:

   * `kernal1', the PET2001 Kernal ROM (4 KBytes) (Commodore ROM images
     901447-06 and 901447-07)

   * `kernal2', the PET3032 Kernal ROM (4 KBytes) (Commodore ROM image
     901465-03)

   * `kernal4', the PET4032/8032 Kernal ROM (4 KBytes) (Commodore ROM
     image 901465-22)

   * `basic1', the PET2001 Basic 1 ROM (8 KBytes) (Commodore ROM images
     901447-09, 901447-02, 901447-03, 901447-04.bin.  The -09 ROM is
     the revised -01 ROM)

   * `basic2', the PET3032 Basic 2 ROM (8 KBytes) (Commodore ROM images
     901465-01 and 901465-01)

   * `basic4', the PET4032/8032 Basic 4 ROM (12 KBytes) (Commodore ROM
     images 901465-23, 901465-20 and 901465-21.  The -23 ROM is a
     revised -19 ROM)

   * `edit1g', the PET2001 editor for graphics keyboards (2 KBytes)
     (Commodore ROM image 901447-05)

   * `edit2b', the PET3032 editor for business keyboards (2 KBytes)
     (Commodore ROM image 901474-01)

   * `edit2g', the PET3032 editor for graphics keyboards (2 KBytes)
     (Commodore ROM image 901447-24)

   * `edit4g40', the PET4032 editor for graphics keyboards (2 KBytes)
     (Commodore ROM image 901498-01)

   * `edit4b40', the PET4032 editor for business keyboards (2 KBytes)
     (Commodore ROM image 901474-02)

   * `edit4b80', the PET8032 editor for business keyboards (2 KBytes)
     (Commodore ROM image 901474-04-?)

   * `chargen', the character generator ROM (2k).  It has two sets with
     128 chars each.  The second (inverted) half of each set is
     computed from the first half by inverting it.  This is a PET
     hardware feature.  (Commodore ROM image 901447-10)

   * `chargen.de', the character generator ROM (2k). This version is a
     patched German charset, with the characters [, \ and ] replaced by
     umlauts.  It has been provided by U. Guettich and he reports that
     it is supported by some programs.

   * `characters.901640-01.bin', the SuperPET character generator ROM
     (4k).  The first half is the same as `chargen', the second half
     contains, instead of an upper and lower case set, an ASCII
     character set and an APL character set. For these sets, the screen
     code is equal to the ASCII/APL code.

   * `waterloo-[abcdf]000.901898-0[1-5].bin',
     `waterloo-e000.901897-01.bin'.  The Waterloo system ROMs.

The PETs also have sockets for extension ROMs for the addresses
$9000-$9FFF, $A000-$AFFF and $B000-$BFFF (the last one for PET2001 and
PET3032 only).  You can specify ROM image files for those extensions
command line options `-petrom9', `-petromA' and `-petromB' resp.

An alternative would be to specify a long kernal ROM with the `-kernal'
option that includes the extension ROM areas.

Also, you can specify replacements for the basic ROM at $B000-$DFFF
with the `-petromBasic' option and for the editor ROM at $E000-$E7FF
with the `-petromEditor' option.

The CBM-II emulator again uses another setup.  For those models the
kernal used is the same for all.  However, for different amounts of
memory exist different versions of the BASIC ROMs.  The 128k RAM version
(C610, C710, B128) uses one bank of 64k for the BASIC text and another
one for all the variables.  The 256k RAM version uses one bank for text,
one for variables, one for arrays and one for strings.

Also the character generator ROMs have a format different from the
above.  The other character ROMs have 8 bytes of pixel data per
character.  Those ROMs have 16 bytes per character instead.  The C6x0
only uses the first 8 of it, but the C7x0 uses 14 lines per character
and needs those increased ROMs.  Both ROMs hold, like the PET, two
character sets with 128 characters each.  Again the second half of the
full (256 char) character set is computed by inverting.

   * `kernal', the KERNAL (8k) for the business machines (6xx/7xx)

   * `kernal.500', the KERNAL (8k) for the personal machine (510)
     (901234-02)

   * `basic.128', the CBM-II 128k BASIC (16k)

   * `basic.256', CBM-II 256k BASIC (16k)

   * `basic.500', C510 BASIC (16k) (901236-02 + 901235-02)

   * `chargen.500', character generator ROM for the C5x0 (4k)
     (901225-01)

   * `chargen.600', character generator ROM for the C6x0 (4k)

   * `chargen.700', character generator ROM for the C7x0 (4k)



File: vice.info,  Node: Keymap files,  Next: Palette files,  Prev: ROM files,  Up: System files

4.2 Keymap files
================

"Keymap files" are used to define the keyboard layout, defining which
key (or combination of keys) must be mapped to each keysym.

In other words, the keyboard emulation works like this: whenever the
user presses or releases a key while the emulation window has the input
focus, the emulator receives an X-Window event with a value that
identifies that key.  That value is called a "keysym" and is unique to
that key.  The emulator then looks up that keysym in an internal table
that tells it which key(s) to press or release on the emulated keyboard.

This table is described by the keymap file, which is made up of lines
like the following:

KEYSYM ROW COLUMN SHIFTFLAG

Where:

   * `KEYSYM' is a string identifying the keysym: you can use the `xev'
     utility (shipped with the X Window system) to see what keysym is
     bound to any key;

   * `ROW' and `COLUMN' identify the key on the emulated keyboard;

   * `SHIFTFLAG' can have one of the following values:

        * `0': the key is never shifted;

        * `1': the key is shifted;

        * `2': the key is the left shift;

        * `4': the key is the right shift;

        * `8': the key can be (optionally) shifted by the user.



The `SHIFTFLAG' is useful if you want certain keys to be "artificially"
shifted by the emulator, and not by the user.  For example, <F2> is
shifted on the C64 keyboard, but you might want it to be mapped to the
unshifted <F2> key on the PC keyboard.  To do so, you just have to use
a line like the following:

F2 0 4 1

where `0' and `4' identify the key (row 0, column 4 on the keyboard
matrix), and `1' specifies that every time the user presses <F2> the
shift key on the C64 keyboard must be pressed.

There are also some special commands you can put into the keyboard file;
they are recognized because they start with an exclamation mark:

   * `!CLEAR' clears the currently loaded keyboard map; it is necessary
     to put this at the beginning of the file if you want the keymap
     file to override all of the current internal settings;

   * `!LSHIFT', `!RSHIFT', followed by a row and a column value,
     specify where the left and right shift keys are located on the
     emulated keyboard; for example, C64 default keymaps will specify

     !LSHIFT 1 7
     !RSHIFT 6 4


Any line starting with the `#' sign, instead, is completely ignored.
This is useful for adding comments within the keymap file.

VICE keymap files have the `.vkm' default extension, and every emulator
comes with a default positional mapping and a default symbolic mapping.


File: vice.info,  Node: Palette files,  Next: Romset files,  Prev: Keymap files,  Up: System files

4.3 Palette files
=================

"Palette files" are used to specify the colors used in the emulators.
They are made up of lines like the following:

RED GREEN BLUE DITHER

where `RED', `GREEN' and `BLUE' are hexadecimal values ranging from 0
to FF and specifying the amount of red, green and blue you want for
each color and `DITHER' is a 4-bit hexadecimal number specifying the
pattern you want when rendering on a B/W display.

You have to include as many lines as the number of colors the emulated
machine has, and the order of the lines must respect the one used in the
machine (so the N'th line must contain the specifications for color N -
1 in the emulated machine).

Lines starting with the `#' sign are completely ignored.  This is
useful for adding comments (such as color names) within the palette
file.

For example, the default PET palette file (which has only two colors, 0
for background and 1 for foreground), looks like the following:

#
# VICE Palette file
#
# Syntax:
# Red Green Blue Dither
#

# Background
00 00 00 0

# Foreground
00 FF 00 F


File: vice.info,  Node: Romset files,  Prev: Palette files,  Up: System files

4.4 Romset files
================

The Romset files are not used by default on all emulators.  You might
have recognized that the names of the ROM images are saved in
resources. Loading a Romset file now just means a `shortcut' to
changing all the resources with ROM image names and reloading the ROMs.

The PET and CBM-II emulators use this feature to change between the
different ROM versions available for those machines. E.g. the Romset
file for the PET 2001 is

KernalName="pet2001"
EditorName=
ChargenName="chargen"
RomModule9Name=
RomModuleAName=
RomModuleBName=

As you can see, the file even uses the same syntax as the resource
file, it is just a bit stripped down.

5 Basic operation
*****************

This section describes the basic things you can do once the emulator
has been fired up.

File: vice.info,  Node: Emulation window,  Next: Menus,  Prev: Basics,  Up: Basics

5.1 The emulation window
========================

When the emulator is run, the screen of the emulated machine is
displayed in a standard X Window which we will call the "emulation
window".  This window will be updated in real time, displaying the same
contents that a real monitor or TV set would.

Below the emulation window there is an area which is used to display
information about the state of the emulator; we will call this area the
"status bar".

On the extreme left of the status bar, there is a "performance meter".
This displays the current relative speed of the emulator (as a
percentage) and the update frequency (in frames per second).  All the
machines emulated are PAL, so the update frequency will be 50 frames
per second if your system is fast enough to allow emulation at the
speed of the real machine.

On the extreme right of the status bar, there is a "drive status
indicator".  This is only visible if the hardware-level ("True") 1541
emulation is turned on.  In that case, the drive status indicator will
contain a rectangle emulating the drive LED and will display the current
track position of the drive's read/write head.


File: vice.info,  Node: Menus,  Next: Help,  Prev: Emulation window,  Up: Basics

5.2 Using the menus
===================

It is possible to execute some commands and change emulation parameters
while the emulator is running: when the pointer is over the emulation
window, two menus are available by pressing either the left or right
mouse buttons.  The left mouse button will open the "command menu" from
which several emulation-related commands can be executed; the right
mouse button will open the "settings menu" from which emulation
parameters can be changed.  The basic difference between the command and
the settings menu is that, while commands have only effect on the
current session, settings can be saved and later used with the "Save
settings" and "Load settings" right-button menu items, respectively.
"Restore default settings" restores the factory defaults.  *Note
Settings and resources::. for more information about how settings work
in VICE.

Sometimes commands can be reached via "shortcuts" or "hotkeys", i.e.,
it is possible to execute them by pressing a sequence of keys instead
of going through the menu with the mouse.  Where shortcuts exist, they
are displayed in parentheses at the right edge of the menu item.  In
VICE, all shortcuts must begin with the <Meta> or <Alt> key.  So, for
example, to attach a disk image to drive #8 (the corresponding menu
item displays "M-8"), you have to press the <Meta> (or <Alt>) and then
<8>.

Note that no other key presses are passed on to the emulated machine
while either <Meta> or <Alt> are held down.


File: vice.info,  Node: Help,  Next: File Selector,  Prev: Menus,  Up: Basics

5.3 Getting help
================

At any time, if you get stuck or do not remember how to perform a
certain action, you can use the "Browse manuals" command (left button
menu).  This will popup a browser and open the HTML version of this
documentation.  Notice that this requires VICE to be properly (and
fully) installed with a `make install'.

The browser can be specified via the `HTMLBrowserCommand' string
resource (*note Settings and resources:: for information about
resources).  Every `%s' in the string will be replaced with a URL to
the VICE HTML pages.


File: vice.info,  Node: File Selector,  Next: Disk and tape images,  Prev: Help,  Up: Basics

5.4 Using the file selector
===========================

In those situations where it is necessary to specify a file name, all
of the VICE emulators will pop up a file selector window allowing you
to select or specify a file interactively.

To the left of the file selector, there is a list of ancestor
directories: by clicking on them, you can ascend the directory tree.  To
the right, there is a list of the files in the current directory; files
can be selected by clicking on them.  If you click on a directory, that
directory becomes the current one; if you click on an ordinary file, it
becomes the active selection.

At the top, there is a "directory box", with the complete path of the
current directory, and a "file name box", with the name of the
currently selected file.  At the bottom there are two buttons: "OK"
confirms the selected file and "Cancel" abandons the file selector
without cancelling the operation.

It is also possible to specify what files you want to show in the file
selector by writing an appropriate shell-like pattern in the directory
box; e.g., `~/*.[dx]64' will only show files in the home directory whose
name ends with either `.d64' or with `.x64'.


File: vice.info,  Node: Disk and tape images,  Next: Reset,  Prev: File Selector,  Up: Basics

5.5 Using disk and tape images
==============================

The emulator is able to emulate disk drives and (read-only) tape
recorders if provided with suitable "disk images" or "tape images".  An
"image" is a raw dump of the contents of the media, and must be
"attached" before the emulator can use it.  "Attaching" a disk or tape
image is like "virtually" inserting a diskette or a cassette into the
disk drive or the tape recorder: once an image is attached, the
emulator is able to use it as a storage media.

There are five commands (in the left button menu) that deal with disk
and tape images:

   * Attach Disk Image

   * Detach Disk Image

   * Attach Tape Image

   * Detach Tape Image

   * Smart-attach a file


The first four commands are used to insert and remove the virtual disks
and cassettes from the respective units.  On the other hand, the last
commands tries to guess the type of the image you are attaching from
its name and size, and attaches it to the most reasonable device.

Supported formats are `D64' and `X64' for disk images (devices 8, 9 and
10) and `T64' for tape images.  Notice that `T64' support is
_read-only_, and that the cassette is automatically rewound when you
reach its end.

Another important feature is that raw Commodore BASIC binary files and
.P00 files can be attached as tapes.  As you can autostart a tape image
when it is attached (*note Autostart::), this allows you to autostart
these particular files as well.

You can attach a disk for which you do not have write permissions: when
this happens, the 1541 emulator will emulate a write-protected disk.
This is also useful if you want to prevent certain disk images from
being written to; in the latter case, just remove the write permission
for that file, e.g., by doing a `chmod a-w'.

* Menu:

* Previewing contents::         Looking into the image before attaching it.
* Autostart::                   Starting a program automagically.
* Compressed files::            Dealing with compressed files.
* Zipcode and Lynx::            Using Zipcoded ([1-4]!*) and Lynx files.


File: vice.info,  Node: Previewing contents,  Next: Autostart,  Prev: Disk and tape images,  Up: Disk and tape images

5.5.1 Previewing the image contents
-----------------------------------

It is possible to examine the directory of a disk or tape image before
attaching it.  Just press the "Contents" button in the file selector
window and a new window will pop up with the contents of the selected
image.

Notice that this function automatically translates the directory from
PETSCII to ASCII; but, due to differences in the two encodings, it is
not always possible to translate all the characters, so you might get
funny results when "weird" characters such as the semi-graphical ones
are being used.


File: vice.info,  Node: Autostart,  Next: Compressed files,  Prev: Previewing contents,  Up: Disk and tape images

5.5.2 "Autostarting" an image
-----------------------------

If you want to reset the machine and run the first program on a certain
image without typing any commands at the Commodore BASIC prompt, you can
use the "Autostart" button in the file selector window after selecting
a proper disk or tape image file.

Notice that, if true drive emulation is turned on, it will be turned off
before running the program and then turned on again after it has been
loaded.  This way, you get the maximum possible speed while loading the
file, but you do not lose compatibility once the program itself is
running.

This method is not completely safe, because some autostarting methods
might cause the true drive emulation not to be turned on again.  In such
cases, the best thing to do is to disable kernal traps (which will cause
true drive emulation to be always kept turned on), or to manually load
the program with true drive emulation turned on.


File: vice.info,  Node: Compressed files,  Next: Zipcode and Lynx,  Prev: Autostart,  Up: Disk and tape images

5.5.3 Using compressed files
----------------------------

It is also possible to attach disk or tape images that have been
compressed through various algorithms; compression formats are
identified from the file extension.  The following formats are supported
(the expected file name extension is in parenthesis):

   * GNU Zip (`.gz' or `.z');

   * BZip version 2 (`.bz2');

   * PkZip (`.zip');

   * GNU Zipped TAR archives (`.tar.gz', `.tgz');

   * Zoo (`.zoo').

PkZip, `tar.gz', `lha' and `zoo' support is _read-only_ and always uses
the _first_ `T64' or `D64' file in the archive.  So archives containing
multiple files will always be handled as if they contain only a single
file.

Windows and MSDOS don't contain the needful programs to handle
compressed archives. Get gzip and unzip for Windows at
ftp://ftp.freesoftware.com/pub/infozip/WIN32 and for MSDOS at
ftp://ftp.freesoftware.com/pub/infozip/MSDOS. Don't use pkunzip for
MSDOS, it doesn't work. The programs to use BZip2 archives may be found
at http://sourceware.cygnus.com/bzip2.  Just put the programs
(unzip.exe, gzip.exe, bzip2.exe) into a directory of your search path
(e.g. C:\DOS or C:\WINDOWS\COMMAND; have a look at the PATH variable).


File: vice.info,  Node: Zipcode and Lynx,  Prev: Compressed files,  Up: Disk and tape images

5.5.4 Using Zipcode and Lynx images
-----------------------------------

Since version 0.15, the VICE emulators have been able to attach disks
packed with Zipcode or Lynx directly, removing the need to manually
convert them into `D64' or `X64' files with `c1541'.  This is achieved
by automatically invoking `c1541', letting it decode the file into a
temporary image and attaching the resulting temporary image read-only.
For this to work, the directory containing `c1541' must be in your
`PATH'.

This uses the `-unlynx' and `-zcreate' options of `c1541' (*note c1541
commands and options::); these commands are not very reliable yet, and
could fail with certain kinds of Lynx and Zipcode images (for example,
they cannot deal with `DEL' files properly).  So please use them with
caution.

Lynx files usually come as `.lnx' files which are unpacked into single
disk images.  On the other hand, Zipcode files do not have a particular
extension (although `.z64' is sometimes used), and represent a disk by
means of component files, named as follows:

   * `1!NAME'

   * `2!NAME'

   * `3!NAME'

   * `4!NAME'

If you attach as a disk image (or smart-attach) any one of these files,
the emulator will simply pick up the other three (by examining the
name) and then build a disk image using all four.


File: vice.info,  Node: Reset,  Prev: Disk and tape images,  Up: Basics

5.6 Resetting the machine
=========================

You can reset the emulated machine at any time by using the "Reset"
command from the command menu.  There are two types of reset:

   * "soft reset", which simply resets the CPU and all the other chips;

   * "hard reset", which also clears up the contents of RAM.

A "soft reset" is the same as a hardware reset achieved by pulling the
RESET line down; a "hard reset" is more like a power on/power off
sequence in that it makes sure the whole RAM is cleared.

It is possible that a soft reset may not be enough to take the machine
to the OS initialization sequence: in such cases, you will have to do a
hard reset instead.

This is especially the case for the CBM-II emulators.  Those machines
examine a memory location and if they find a certain "magic" value they
only do what you know from the C64 as `Run/Stop-Restore'.  Therefore,
to really reset a CBM-II use hard reset.

6 Settings and resources
************************

In the VICE emulators, all the settings are stored in entities known as
called "resources".  Each resource has a name and a value which may be
either an integer or a string.  Integer values are often used as
boolean values with the usual convention of using zero for "false" and
any other value for "true".

Resource values can be changed via the right-button menu (the
"settings" menu), via command-line options or via the "resource file".

The "resource file" is a human-readable file containing resource
values: it is called `vicerc' and is stored in the directory `.vice/'
in the user's home directory.  It is possible to dump the current
values of the resources into that file or load the values stored into
that file as the current values, at any time.  This is achieved with
the "Save settings" and "Load settings" right menu items.  A third menu
item, "Restore Default Settings", can be used to reset all the values
to the factory defaults.

A special resource, `SaveResourcesOnExit', if set to a non zero value,
causes the emulator to ask you if you want to save the current
(changed) settings before exiting, and can be toggled with the "Save
settings on exit" command from the right-button menu.

Notice that not all the resources can be changed from the menus; some of
them can only be changed by manually modifying the resource file or by
using command-line options.

* Menu:

* Resource files::              Format of resource files.
* Resources and command-line::  Specifying settings from the

6.1 Format of resource files
============================

A resource file is made up of several sections; sections have the
purpose of separating the resources of a certain emulator from the ones
of the other emulators.  A section starts with the name of an emulator
in brackets (e.g., `[C64]') and ends when another section starts or
when the file ends.

Every line in a section has the following format:

RESOURCE=VALUE

where `RESOURCE' is the name of a resource and `VALUE' is its assigned
value.  Resource names are case-sensitive and resource values are
either strings or integers.  Strings must start and end with a double
quote character (`"'), while integers must be given in decimal notation.

Here is an example of a stripped-down `.vice/vicerc' file:

[VIC20]
HTMLBrowserCommand="netscape %s"
SaveResourcesOnExit=0
FileSystemDevice8=1
FSDevice8ConvertP00=1
FSDevice8Dir="/home/ettore/cbm/stuff/vic20p00"
FSDevice8SaveP00=1
FSDevice8HideCBMFiles=1
[C64]
HTMLBrowserCommand="netscape %s"
SaveResourcesOnExit=1
FileSystemDevice8=1
FSDevice8ConvertP00=1
FSDevice8Dir="/home/ettore/cbm/stuff/c64p00"
FSDevice8SaveP00=1
FSDevice8HideCBMFiles=1

Notice that, when resource values are saved with "Save settings", the
emulator only modifies its own section, leaving the others unchanged.

6.2 Using command-line options to change resources
==================================================

Resources can also be changed via command-line options.

Command-line options always override the defaults from `.vice/vicerc',
and their assignments last for the whole session.  So, if you specify a
certain command-line option that changes a certain resource from its
default value and then use "Save Settings", the value specified with
the command-line option will be saved back to the resource file.

Command-line options can begin with with a minus sign (`-') or with a
plus sign (`+').  Options beginning with a minus sign may require an
additional parameter, while the ones beginning with the plus sign never
require one.

Moreover, options beginning with a plus sign always have a counterpart
with the same name, but with a minus sign; in that case, the option
beginning with a minus sign is used to _enable_ a certain feature,
while the one beginning with a plus sign is used to _disable_ the same
feature (this is an X11 convention).  For example, `-mitshm' enables
support of MITSHM, while `+mitshm' disables it.

6.3 Autostart settings
======================

6.3.1 Autostart resources
-------------------------

`AutostartPrgDiskImage'
     String specifying the filename of the disk image used when
     autostarting a prg file and "copy to D64" is enabled.  

`AutostartBasicLoad'
     Boolean, if true load to basic start using ,8 when autostarting.  

`AutostartRunWithColon'
     Boolean, if true put a colon after the load command when
     autostarting.  

`AutostartHandleTrueDriveEmulation'
     Boolean, if true handle (enable/disable) True Drive Emulation on
     autostart.  

`AutostartWarp'
     Boolean, if true temporarily enable warp mode when autostarting 

`AutostartPrgMode'
     Integer specifying the autostart mode for prg files. (0: virtual
     filesystem, 1: inject to RAM, 2: copy to D64) 

`AutostartDelayRandom'
     Boolean, enables a short random delay on autostart.  

`AutostartDelay'
     Integer specifying the maximum delay in frames.

6.4 Performance settings
========================

It is possible to control the emulation speed by using the "Maximum
speed" menu item in the right-button menu.  The default setting is
`100', which causes the emulation to never run faster than the real
machine.  A higher value allows the emulator to run faster, a lower one
may force it to run slower.  The setting "No limit" means to run as
fast as possible, without limiting speed.

It is also possible to control the emulator's rate of frame update using
the "Refresh rate" setting; the value ranges from "1/1" (update 1/1 of
the frames of the real machine, that is 50 frames per second) to "1/10"
(update 1 every 10 frames) and can be changed via the "Refresh Rate"
submenu.  The "Auto" setting means to dynamically adapt the refresh
rate to the current speed of the host machine, making sure the maximum
speed specified by the via "Maxium speed" is always reached if
possible.  In any case, the refresh rate will never be worse than 1/10
if this option is specified.

Note that you cannot simultaneously specify "Auto" as the refresh rate
and "No limit" as the maximum speed..

Moreover, a special "warp speed" mode is provided and can be toggled
with the "Enable Warp Mode" menu item.  If this mode is enabled, it
will cause the emulator to disable any speed limit, turn sound emulation
off and use a 1/10 refresh rate, so that it will run at the maximum
possible speed.

---------------------------

`Speed'
     Integer specifying the maximum relative speed, as a percentage.
     `0' stands for "no limit".

`RefreshRate'
     Integer specifying the refresh rate; a value of `n' specifies a
     refresh rate of 1/`n'.  A value of `0' enables automatic frame
     skipping.

6.5 Video settings
==================

The following right-button menu items control the video output.  On
emulators that include two video chips (like `x128') all options but
XSync exist twice, once for each chip.  XSync is shared between the
video chips.

   * "Video Cache" enables a video cache that can speed up the emulation
     when little graphics activity is going on; it is especially useful
     when you run the emulator on a networked X terminal as it can
     reduce the network bandwidth required.  However, this setting can
     actually make the emulator slower when there is little graphics
     activity and the amount of work needed to maintain the cache is
     greater than the amount of work that would be wasted by not using
     it (if any).

   * "Double Size" toggles "double-size mode", which makes the
     emulation window twice as big.  When emulating a 80-column PET,
     only the height is doubled, so that the aspect ratio is closer to
     that of the real thing.

   * "Double Scan" toggles "double-scan mode", which causes the
     emulator to draw only odd lines when running in double-size mode
     (this saves some CPU time and also makes the emulation window look
     more like an old monitor).

   * `Use XSync()" causes the emulator to call the X11 function
     `XSync()' before updating the emulation window: this might be
     necessary on low-end systems to prevent it from consuming so many
     system resources that it becomes impossible for the user to
     interact with it.

6.5.1 using openGL Rastersynchronization under X11
--------------------------------------------------

Warning: To get full retro experience with synchronization to the
vertrical raster retrace messing with X11 modelines (resolution and
refresh frequencies) is necessary. This description is a suggestion -
Follow this instructions at your own risk!

The following was tested under Ubuntu Linux (8.04) featuring Xorg
Xserver 1:7.3+10ubuntu and mesa openGL including HW support (NVIDIA
driver) supporting glx version 1.4 supplying GLX_SGI_video_sync.

It is assumed that this works also on other systems supporting the
required extensions.

Preconditions:
   * openGL extension GLX_SGI_video_sync in your X11 setup.    The
     availability of the extension is checked at startup.

   * XRandR extension to switch proper modes (50Hz for PAL, 60Hz for
     NTSC) is mandatory, proper modelines in your /etc/X11/xorg.conf
     must be present.

If your systems lacks 50 or 60Hz modes you might try using `gtf'
(typcally shipped with Xorg, xserver) - see related man page.

You might need to add the output such as:
# 800x600 # 50.00 Hz (GTF) hsync: 30.90 kHz; pclk: 31.15 MHz
Modeline "800x600_50.00" 31.15 800 824 904 1008 600 601 604 618 -HSync +Vsync
to you Monitor Section of /etc/X11/xorg.conf and add the resolution to
the `Screen' section.

Sometimes some consistency checks within the display driver drop this
resolutions again.  To drop e.g. the autodetection features in the
NVIDIA driver you might add `Option "UseEDID" "FALSE"' in section
`Device'.

XRandR cannot cope properly with the DynamicTwinView feature of the
proprietary nvidia driver. You might need

`Option         "DynamicTwinView" "False"'

to get proper results (in Screen or Device section of you xorg.conf).

ATTENTION: Disabling such features might allow X11 to access your HW in
a way that it gets damaged! You are at your own risk!

Enable fullscreen (not necessary, but makes sense):
   * choose your preferred resolution/refresh XRandR Resolutions and
     enable XRandR as fullscreen device (50Hz/PAL or 60Hz/NTSC mode).

   * Activate fullscreen with `Alt-D'.

   * choose `OpenGL Rastersynchronization' in the video chip menu
     (VIC-II Settings, VIC Setting, etc.)

Note that:
   * the current implementation is dropping synchronization silently in
     case the display frequency isn't aligned (50Hz for PAL, 60Hz for
     NTSC).

   * On some systems the XRandR system isn't informed about desktop
     display frequency changes if you switch resolutions via hotkeys
     like CTRL-Alt-+ (Numpad), which is possible e.g. with the X11
     implementation of Xorg.

     In that case you can override/tell the current frequency via menu:
     Settings->VICII Settings->Desktop Refreshrate (e.g. in x64) (this
     shouldn't be necessary if you use fullscreen via XRandR.

6.5.2 Video resources
---------------------

The following resources affect the screen emulation.

`UseXSync'
     Boolean specifying whether `XSync()' is called after updating the
     emulation window.

`MITSHM'
     Integer specifying whether VICE should try to use the shared memory
     extensions (MITSHM) when starting up.  The shared memory
     extensions make things a lot faster but might not be available on
     your system.  You will not be able to use these extensions if you
     are sitting at an X terminal while running the emulator on a
     remote machine across a network.  Valid values are: 0 = do not use
     MITSHM, 1 = do use MITSHM, -1 = try to autodetect availability on
     startup (default).  The last is a simple test if the emulator runs
     across a network and if so disables MITSHM (If you have problems
     with this test please report it).

`PrivateColormap'
     Boolean specifying whether VICE should install a private colormap
     at startup.  This makes sense for 8-bit displays that could run
     out of colors if other color-hungry applications are running at
     the same time.

`DisplayDepth'
     Integer specifying the depth of the host display.  The value `0'
     (the default) causes the emulator to autodetect it.

`UseFullscreen'
     Boolean specifying whether fullscreen mode is currently in use.  

`HwScalePossible'
     Boolean that indicates whether hardware scaling is possible or not.  

`openGL_sync'
     Boolean, if true enable Open-GL frame sync.  

`openGL_no_sync'
     Boolean, if true Open-GL sync is not available.  

`KeepAspectRatio'
     Boolean specifying whether the aspect ratio of the output window
     should be preserved. (0=free scaling, 1=scale with fixed aspect
     ratio) 

`TrueAspectRatio'
     Boolean specifying whether to use the true (non square pixels)
     aspect ratio.

`Window0Width'
`Window0Height'
`Window0Xpos'
`Window0Ypos'
     Integers specifying the position and size of the (first) emulator
     window.  

`Window1Width'

6.8 Sound settings
==================

The following menu items control sound output:

   * "Enable sound playback" turns sound emulation on and off.

   * "Sound synchronization" specifies the method for syncronizing the
     sound playback.  Possible settings are:
        * "Flexible", i.e., the audio renderer flexibly adds/removes
          samples to the output to smoothly adapt the playback to
          slight changes in the speed of the emulator.

        * "Adjusting" works like "flexible", but supports bigger
          differences in speed.  For example, if the emulation speed
          drops down from from 100% to 50%, audio slows down by the
          same amount too.

        * "Exact", instead, makes the audio renderer output always the
          same sounds you would hear from the real thing, without
          trying to adapt the ratio; to compensate the tolerances in
          speed, some extra frames will be skipped or added.

   * "Sample rate" specifies the sampling frequency, ranging from 8000
     to 48000 Hz (not all the sound cards and/or sound drivers can
     support all the frequencies, so actually the nearest candidate
     will be chosen).

   * "Buffer size" specifies the size of the audio buffer; the bigger
     the buffer, the longer the delay with which sounds are played.
     You should pick the smallest value your machine can handle without
     problems.

   * "Sound suspend time", will cause the audio playback to pause for
     the specified number of seconds whenever some clicking happens.
     If "Keep going" is selected, no pausing is done.

          specifies the audio device, `/dev/audio' by default);

        * `sun', for the Solaris audio device (unfinished;
          `SoundDeviceArg' specifies the audio device, `/dev/audio' by
          default).

        * `hpux', for the HP-UX audio device (unfinished;
          `SoundDeviceArg' specifies the audio device, `/dev/audio' by
          default).

        * `sdl', for the Simple DirectMedia Layer audio driver.

        * `esd', for EsounD, the Enlightened Sound Daemon;
          `SoundDeviceArg' specifies the ESD server (`host:port') to
          connect, empty by default.

        * `dummy', fully emulating the SID, but not actually playing
          samples.

        * `dump', writing all the write accesses to the registers to a
          file (specified by `SoundDeviceArg', default value is
          `vicesnd.sid');

        * `speed', like `dummy' but also calculating samples (mainly
          used to evaluate the speed of the sample generator);

        * `fs', writing samples to a file (specified by
          `SoundDeviceArg'; default is `vicesnd.raw');

     based on the presence of a stereo sid), 'always mono' (output is
     always mono, stereo streams are mixed into a mono stream) or
     'always stereo' (output is always stereo, mono streams are
     multiplexed to a stereo stream). (0=system, 1=mono, 2=stereo)

6.10 Drive settings
===================

These settings are used to control the hardware-level emulation of the
Disk drives.  When hardware-level emulation is turned on, only drives 8
and 9 are being emulated.

The following settings affect both drives:

   * "Enable true drive emulation" enables the (slow) hardware-level
     emulation of the drives for maximum compatibility.  This must be
     turned on for any of the following settings to have effect.

   * "Drive sync factor" specifies the speed of the drive's CPU.  This
     can be used to help loading certain programs that have trouble
     with the default PAL setting (for example, programs designed for
     NTSC machines).  The ratio is calculated as follows:

     sync_factor = 65536 * clk_drive / clk_machine

     where `clk_drive' and `clk_machine' are clock speeds in MHz.  The
     menu lets you choose between the PAL and NTSC values, and also lets
     you specify whatever value you want.  Be careful when changing it,
     though, because a wrong value can break things and even corrupt
     disk images.


The following settings, instead, are specific of each drive:

   * "Drive model" specifies the model of the drive being emulated.
     *Warning:* This will reset the drive.

   * "Enable parallel cable" enables emulation of a SpeedDOS parallel
     cable; if you switch this option on and replace the original
     Commodore ROMs with SpeedDOS-compatible ones, you can speed up
     loading/saving times.

   * "Idle method" specifies which method the drive emulation should
     use to save CPU cycles in the host CPU.  There are three methods:

        * "Skip cycles": Each time the serial line is accessed by the
          C64, the drive executes all the cycles since the last time it
          ran.  If the number of elapsed cycles is larger than a
          certain value, the drive discards part of them.

        * "Trap idle": The disk drive is still emulated upon serial line
          accesses as with the previous option, but it is also always
          emulated at the end of each screen frame.  If the drive gets
          into the DOS idle loop, only pending interrupts are emulated
          to save time.

        * "No traps": Like "Trap idle", but without any traps at all.
          So basically the drive works exactly as with the real thing,
          and nothing is done to reduce the power needs of the drive
          emulation.

     The first option ("Skip cycles") is usually best for performance,
     as the drive is emulated as little as possible; on the other hand,
     you may notice sudden slowdowns (when the drive executes several
     cycles at once) and the LED status is never updated (because it
     would not be possible to do correctly so).  Moreover, if the drive
     tries to get in sync with the computer in some weird way and the
     computer does not access the serial line for a long time, it is
     possible that some cycles are discarded and the sync is lost.
     Notice that this hack will have no effect on performance if a
     program continuously reads from the IEC port, as the drive will
     have to be fully emulated in any case (some stupid programs do
     this, even when they don't actually need to use the drive).

     The second option ("Trap idle") is usually a bit slower, as at
     least interrupts are always emulated, but ensures the LED state is
     always updated correctly and always keeps the drive and the
     computer in sync.  On the other hand, if a program installs a
     non-standard idle loop in the drive, the drive CPU has to be
     emulated even when not necessary and the global emulation speed is
     then _much_ slower.

   * "40-track image support" specifies how 40-track ("extended") disk
     images should be supported.  There are three possible ways:

        * "Never extend" never extends disk images at all (so if a
          program tries to write tracks beyond the 35th, it is not
          allowed to do so);

        * "Ask on extend" prompts the user as soon as a program tries
          to write tracks beyond the 35th, and the user can then choose
          whether he wants the disk image to be extended or not;

        * "Extend on access" simply extends the disk image as soon the
          program needs it, without prompting the user.

6.11 Peripheral settings
========================

VICE is able to support some special peripherals:

   * "file system devices", pseudo-drives accessing the Unix file
     system;

   * printers.

These features depend on some "kernal traps" that replace the existing
routines in the original Commodore operating system with custom-made C
routines.

* Menu:

* File system device settings::  Settings for file system devices.
* Printer settings::            Settings for emulating a printer.
* No kernal traps::             Disabling kernal traps completely.


File: vice.info,  Node: File system device settings,  Next: Printer settings,  Prev: Peripheral settings,  Up: Peripheral settings

6.11.1 Settings for file system devices
---------------------------------------

These settings deal with the drive-like peripherals connected to the bus
of the emulated machine.  The first setting relates to the parallel
IEEE488 interface. With this interface a special engine is used to
listen to the bus lines to translates them to the filesystem code. Thus
the PET will always detect a drive for example, but it can also use
drives 10 and 11 even together with true disk drive emulation.

   * "Enable virtual devices", enables the peripheral access via the
     fast disk emulation (either kernal traps or IEEE488 interface).
     Both, filesystem and disk image access via fast drive emulation,
     are affected.

Four peripherals, numbered from 8 to 11, are accessible; each of them
provides the following settings:

   * "File system access", if enabled, allows the device to emulate a
     drive accessing a file system directory; note that when a disk
     image is attached to the same drive, the directory is no longer
     visible and the attached disk is used instead.

   * "File system directory" specifies the directory to be accessed by
     the drive.

   * "Convert P00 file names", if enabled, allows access to P00 files
     using their built-in name instead of the Unix one.

   * "Create P00 files on save", if enabled, creates P00 files (instead
     of raw CBM files) whenever a program creates a file.

Note that, by default, all drives except 11 create P00 files on save,
while drive 11 creates raw CBM files. Those files come without any
header, but also with the filename restrictions given by the operating
system VICE runs on.

6.11.2 Printer settings
-----------------------

The VICE emulators can emulate printers connected to either the IEC
buffer or the user port.  Emulation can be achieved by redirecting the
printer output to a file or by piping it through an external process.
This is defined by so-called "printer device file names"; a printer
device file name can be either a simple path, or a command name
preceeded by a pipe symbol `|'.

For example, printer device `filename' will cause the output to be
appended to the file `filename', while printer device `|lpr' will cause
the `lpr' command to be executed and be fed the printer output.  The
printer output will not be converted but saved as printed by the
emulated machine.

Up to three printer devices may be specified through the following
resources:

   * device 1, whose default value is `print.dump';

   * device 2, whose default value is `|lpr'.

   * device 3, whose default value is `|petlp -F PS|lpr';

So, basically, by default printer device 1 will dump printer output to
`print.dump'; printer device 2 will print it via `lpr' directly to the
printer and device 3 will print it via `petlp' (a not-yet-complete
utility that will produce Postscript output from the Commodore printer
code) and then to the printer via `lpr'.

6.12 RS232 settings
===================

The VICE emulators can emulate the RS232 device most of the machines
have.  The C64, C128 and VIC20 emulators emulate the userport RS232
interface at 300 and 1200 baud.  The C64 and C128 can also use the 9600
baud interface by Daniel Dallmann, using the shift registers of the two
CIA 6526 chips.  The PET can have a 6551 ACIA RS232 interface when
running as a SuperPET, and the CBM-II has such an ACIA by default.  The
C64 and C128 emulators can emulate an ACIA 6551 (also known as Datapump
for example) as extension at `$de**'.

Emulation can be achieved by either:

   * connecting a real UNIX serial device;

   * dumping to a file;

   * piping through a process.

It is possible to define up to four UNIX serial devices, and then decide
which interface should be connected to which device.  This is done by
so-called "rs232 device file names"; an rs232 device file name can be
either a simple path, or a command name preceeded by a pipe symbol `|'.
If the path specifies a special device (e.g. `/dev/ttyS0') it is
recognized by VICE and the emulator can set the baudrate.

For example, rs232 device `filename' will cause the output to be
written (not appended) to the file `filename', while printer device
`|lpr' will cause the `lpr' command to be executed and be fed the rs232
output.  The rs232 output will not be converted but saved as sent by
the emulated machine.  The same holds true for the rs232 input.  If the
command writes data to the standard output it will be caught by VICE
and sent back to the emulator.  Also the data sent by the pseudo device
will be sent back to VICE.

For example you can setup a null-modem cable between two serial ports
of your PC, setup one port for login and use the other in VICE.  Then
you can login from your emulator via the RS232 emulation and the
null-modem cable to your machine again.

You can not simply run a shell from VICE, as the shell will notice that
it does not run on its own pseudo terminal and will thus buffer its
output.  You need to write some program that opens an own pseudo
terminal and runs the shell from there (not yet finished).

Up to four RS232 devices may be specified through the following
resources:

   * device 1, whose default value is `/dev/ttyS0';

   * device 2, whose default value is `/dev/ttyS1';

   * device 3, whose default value is `rs232.dump';

   * device 4, whose default value is `|lpr'.

For the first two devices you can change the baudrate the tty device is
set to by specifying it on the commandline or in the menu.  This
baudrate is 9600 by default for the latter two, but can be changed only
by resources (The baudrate is independent from the baudrate the emulator
actually expects).

6.12.3 RS232 usage example
--------------------------

Here we give you a simple example how to set up an emulated C64 using
the modem connected to your PC. The following list shows each step.

`Attach your modem to your PC at a serial port.'
     Normally you should set it up to use the modem as "/dev/modem".

`start VICE'

`Setup VICE to use your modem as "serial device 1"'
     Go to the RS232 settings menu and change "Serial 1 device" to
     "/dev/modem" (or the device where you attached your modem to) Then
     go to the RS232 settings menu and change "Serial 1 baudrate" to
     the baudrate your modem should run at.    Watch out, e.g. on Linux
     there is an additional multiplier   to multiply with the baudrate
     (so e.g. 19200 gives 115200 or so baud)   See the "setserial"
     manpage on Linux for example.    However, most modems should be
     able to autodetect the speed to   the computer as well.

`Select the RS232 emulation your programs use'
     If you want to use the Userport emulation, go to the RS232
     settings and   change "Userport RS232 Device" to   "Serial 1". If
     you want ACIA emulation (swiftlink or what's it called?)    then
     change "ACIA $DE** device" to "Serial 1".

`Enable the emulation'
     Go to the RS232 settings and select either "ACIA $DE** emulation"
     or Userport 300/1200 baud or CIA 9600 baud emulation.

`Load your program and start it.'
     If it is able to detect an   RS232 cartridge like swiftlink or so,
     try to detect the ACIA emulation   if enabled.    Otherwise just
     set the baudrate to either 300, 1200 or 9600 according   to what
     you enabled in the VICE menu for the userport.

6.16.1 Miscellaneous resources
------------------------------

`Directory'
     String specifying the search path for system files.  It is defined
     as a sequence of directory names, separated by colons (`:'), just
     like the `PATH' variable in the shell.  The special string `$$'
     stands for the default search path, which is initialized at
     startup to the following value:

     LIBDIR/EMUID:$HOME/.vice/EMUID:BOOTPATH/EMUID:LIBDIR/DRIVES:$HOME/.vice/DRIVES:BOOTPATH/DRIVES

     where:

        * `LIBDIR' is the VICE installation directory (usually
          `/usr/local/lib/vice', `/usr/lib/vice' or `/opt/vice/lib');

        * `EMUID' is the emulation identification string (`C64',
          `C128', `VIC20' or `PET');

        * `BOOTPATH' is the directory where the binary lies (usually
          `/usr/local/bin', `/usr/bin' or `/opt/vice/bin').

        * `DRIVES' is the directory called "DRIVES", where the disk
          drive ROMs are.  (The disk drive ROMs are used by all
          emulators, so there is an extra directory for them.)

     Notice that the middle entry points to a default location in the
     user's home directory. Here private ROM versions (e.g.  speeddos
     or JiffyDos) can be stored for example.

     *Note System files::. for a description of the method used to load
     the emulator's system files.

`HTMLBrowserCommand'
     String specifying the command to run the help browser.  The help
     browser can be any HTML browser, and every `%s' in the string is

     documentation.  For example, the default value `netscape %s' runs
     Netscape Navigator.

`SaveResourcesOnExit'
     Boolean specifying whether the emulator should save changed
     settings before exiting.  If this is enabled, the user will be

File: vice.info,  Node: C64 cartridges,  Next: VIC-II settings,  Prev: C64/128-specific,  Up: C64/128-specific

7.1.1 Using cartridges
----------------------

The cartridge system is organized in "Slots" to allow more than one
cartridge connected at a time, like it can be done using an expansion
port expander on a real C64 (see below).

Generally a cartridge can be enabled by attaching its respective
cartridge image, or using the respective menu option for cartridges
that do not require an image.

x64, x64sc and x128 allow you to attach the following kinds of images:

   * `.crt' images, as used by the CCS64 emulator by Per Håkan Sundell

   * raw `.bin' images, with or without load address

"Cartridge images" are like disk images, but contain the contents of
cartridge ROM and/or RAM images instead of disk images.

To attach cartridges, use the "Attach a cartridge image" submenu. When
using `.crt' images, this will work for every cartridge which is
supported. For raw `.bin' images you might have to use command line
options.

When you have successfully attached a cartridge image, you should then
reset the machine to make sure the cartridge initializes itself. (Or
enable the "reset on cartridge change" option).

Of course, it is also possible to detach a currently attached cartridge
image ("Detach cartridge image").

If you are using a freezer cart like an Action Replay cartridge, you can
emulate the cartridge's freeze button with the "Cartridge freeze"
command.

The imaginary expansion port expander is organized in 4 slots, the
cartridges are associated with them like this:

7.1.1.1 Slot 0
..............

All carts that have a passthrough connector go here. Once a "Slot 0"
cartridge is enabled all further cartridges are connected to its
respective passthrough port.

Only one cartridge of this type can be active at a time.

"Slot 0" carts have individual "enable" switches, enabling means
enabling permanently.

The following cartridges are emulated in this slot:

   * IEEE-488 Interface
     (`http://www.funet.fi/pub/cbm/schematics/cartridges/c64/ieee-488/eprom.bin')

   * Magic Voice

   * MMC64

7.1.1.2 Slot 1
..............

Mostly RAM based cartridges which for one reason or the other might
make sense to be enabled together with one of the "Main Slot"
cartridges go here.

Only one cartridge of this type can be active at a time.

"Slot 1" carts have individual "enable" switches, enabling means
enabling permanently

The following cartridges are emulated in this slot:

   * Double Quick Brown Box (DQBB)

   * Expert Cartridge

   * ISEPIC

   * RamCart

7.1.1.3 Main Slot
.................

All other cartridges which are not pure i/o extensions go here.

Only one cartridge of this type can be active at a time.

Cartridges in the "Main Slot" must be explicitly set as default to
enable them permanently.

The following cartridges are emulated in this slot:

   * generic 4K, 8K and 16K game- and ultimax cartridges

   * Action Replay V5

   * Action Replay MK2

   * Action Replay MK3

   * Action Replay MK4

   * Zaxxon

7.1.1.4 I/O Slot
................

All carts that are pure I/O extensions go here.

Any number of "I/O Slot" Carts may be active at a time.

"I/O Slot" carts have individual "enable" switches, enabling means
enabling permanently.

The following cartridges are emulated in this slot:

   * ACIA (Swiftlink, Turbo232)

   * DigiMAX

   * Ethernet (The Final Ethernet, RR-Net)

   * GEO-RAM

   * MIDI (Passport/Syntech, Datel/Siel/JMS/C-Lab, Maplin, Namesoft,
     Sequential)

   * RAM Expansion Module (REU)

   * SFX Sound Expander

   * SFX Sound Sampler

7.1.1.5 Expected behaviour
..........................

When the emulator is run without arguments, all settings from the
config file should be applied and arguments override settings from the
config file.

When saving the settings to the config file it is expected that on the
next run of the emulator all settings will be in the same state as they
were when saved.

There is an exception to this rule: the cartridge in the "Main Slot"
must be explicitly set as default before it gets saved to the config
file.

`+cart' should disable ALL cartridges, including eventually activated
REU, Swithlink and all similar expansionport devices.

`-cartXYZ' options should generally attach AND activate a cart of type
XYZ.  As a consequence, attaching carts this way which are NOT in the
"Main Slot" will also enable the cart permanently.

7.1.1.6 Common problems
.......................

If attaching a cartridge does not work as expected, this may be because
of various reasons:

   * Not seldomly the CRT type is incorrectly set in `.crt' files found
     "in the wild".  Make sure this is not the case (if in doubt use
     `cartconv' to verify and/or fix).

   * You may have unintentionally enabled more than one cartridge at
     once, for example by saving the settings with REU enabled, and
     then later attaching a game cartridge from the command-line. The
     cartridge system will allow certain combinations, but (as on the
     real thing) not all do (can) actually work. To make sure this is
     not the case, either detach all cartridges from the menus, or use
     `+cart' on the command-line.

   * The cartridge image might be broken. Try one from a different
     source. If you are sure the dump is ok (for example because you
     dumped it yourself) then make sure it is in proper linear order
     (on some cartridges, for example "capture", address and/or data
     lines at the eprom are shuffled around so a dump made with an
     eprom burner can not be used as is).

   * Last not least you might have encountered a bug in the emulation.
     If you suspect this is the case, and you can still reproduce the
     bug after checking the things above, please file a bug report
     including the following information:

        * attach your vicerc and a reference to the cartridge binaries

        * if you can, comment in the respective DEBUGXYZ macros
          prominently defined at the top of these files:
          src/c64/cart/c64cart.c src/c64/cart/c64cartmem.c
          src/c64/c64io.c src/c64/c64export.c and then recompile. this
          will add debug output that might make it much easier to
          locate certain problems.


7.1.1.7 IEEE-488 interface
..........................

To be able to use an IEEE drive, you need to enable IEEE emulation for
the emulator. To do this, follow the following steps:

Download the IEEE 488 ROM image from the CBM archives (formerly known
as FUNET) Attach that image with File/Attach cartridge image/IEEE488
interface image.

Make sure you have a one-drive system only (that is, go to
Settings/Peripheral Setting, uncheck "use IEC device" for all devices,
go to Settings/Drive Settings and select "Floppy type" as "none" for
all drives other than drive 8.

After this, all drives can be selected in x64 and x128.

7.1.1.8 The Final Cartridge 3
.............................

The Final Cartridge 3 detects whether a mouse is connected when it
starts and disables mouse support if it doesnt detect one. So to make
mouse emulation work you must either enable it on the command line, or
reset the cartridge after enabling it from the user interface.

7.1.4 VIC-II settings
---------------------

These settings control the emulation of the VIC-II (MOS6569) video chip
used in both the C64 and the C128.

   * "Sprite-sprite collisions" and "Sprite-background collisions", if
     enabled, cause the hardware detection of sprite-to-sprite and
     sprite-to-background collisions of the VIC-II to be emulated.  This
     feature is used by many games, and disabling either of the two
     detection systems can sometimes make you invincible (although
     there is also a chance that also enemies become invincible then).

   * "Color set" can be used to dynamically change the palette file
     being used by choosing one of the available predefined color sets:

        * `default.vpl' ("default"), the default VICE palette;

        * `c64s.vpl' ("C64S"), palette taken from the shareware C64S
          emulator by Miha Peternel.

        * `ccs64.vpl' ("CCS64"), palette taken from the shareware CCS64
          emulator by Per Håkan Sundell.

        * `frodo.vpl' ("Frodo"), palette taken from the free Frodo
          emulator by Christian Bauer
          (http://www.uni-mainz.de/~bauec002/FRMain.html).

        * `pc64.vpl' ("PC64"), palette taken from the free PC64
          emulator by Wolfgang Lorenz.

        * `godot.vpl' ("GoDot"), palette as suggested by the authors of
          the C64 graphics package GoDot
          (http://users.aol.com/howtogodot/welcome.htm).

   * "Second SID" maps a second SID chip into the address space for
     stereo sound. This emulates e.g. the "SID Symphony Stereo
     Cartridge" from Dr. Evil Laboratories. The second SID can be used
     with software such as "Stereo SID Player" by Mark Dickenson or
     "The Enhanced Sidplayer" by Craig Chamberlain.

   * "Second SID base address" sets the start address for the second SID
     chip. Software normally uses $DE00 or $DF00, since $DE00-$DEFF and
     $DF00-$DFFF can be mapped through the cartridge port of the C64.
     The default start address is $DE00.

   * "Emulate filters" causes the built-in programmable filters of the
     SID chip to be emulated.  A lot of C64 music requires them to be
     emulated properly, but their emulation requires some additional
     processor power.

   * "ChipModel" specifies the model of the SID chip being emulated:
     there are two slightly different generations of SID chips: MOS6581
     ones and MOS8580 ones.

   * "Use reSID emulation" specifies whether the more accurate (and
     resource hungry) reSID emulation is turned on or off.

   * "reSID sampling method" selects the method for conversion of the
     SID output signal to a sampling rate appropriate for playback by
     standard digital sound equipment. Possible settings are:
        * "Fast" simply clocks the SID chip at the output sampling
          frequency, picking the nearest sample. This yields acceptable
          sound quality, but sampling noise is noticeable in some
          cases, especially with SID combined waveforms. The sound
          emulation is still cycle exact.

        * "Interpolating" clocks the SID chip each cycle, and
          calculates each sample with linear interpolation. The
          sampling noise is now strongly attenuated by the SID external
          filter (as long as "Emulate filters" is selected), and the
          linear interpolation further improves the sound quality.

        * "Resampling" clocks the SID chip each cycle, and uses the
          theoretically correct method for sample generation. This
          delivers CD quality sound, but is extremely CPU intensive,
          and is thus most useful for non-interactive sound generation.
          Unless you have a very fast machine, that is.

   * "reSID resampling passband" specifies the percentage of the total
     bandwidth allocated to the resampling filter passband. The work
     rate of the resampling filter is inversely proportional to the
     remaining transition band percentage. This implies that e.g. with
     the transition band starting at ~ 20kHz, it is faster to generate
     48kHz than 44.1kHz samples. For CD quality sound generation at
     44.1kHz the passband percentage should be set to 90 (i.e. the
     transition band starting at almost 20kHz).

7.1.6 C64 I/O extension settings
--------------------------------

I/O extensions are (usually) cartridges which do not map into ROM space,
but use only the I/O space at address range $DE00 ... $DEFF and/or
$DF00 ... $DFFF.

Please use these extensions only when needed, as they might cause
compatibility problems.

The following I/O extensions are available:

   * ACIA (Swiftlink, Turbo232)

   * DigiMAX

   * Ethernet (The Final Ethernet, RR-Net)

   * GEO-RAM

   * MIDI (Passport, Datel, Maplin, Namesoft, Sequential)

   * REU - The "RAM Expansion Module" extension emulates a standard
     Commodore RAM Expansion Unit; this can be used with GEOS and other
     programs that are designed to take advantage of it.  This currently
     works only in the C64 emulator.

   * SFX Sound Expander

   * SFX Sound Sampler

7.3 C64DTV-specific commands and settings
=========================================

This section lists the settings and commands that are C64DTV specific
and thus are not present in the other emulators.

* Menu:

* C64DTV ROM image::
* DTV revision::
* LumaFix::
* Userport::
* Debug::
* Monitor DTV features::


File: vice.info,  Node: C64DTV ROM image,  Next: DTV revision,  Prev: C64DTV-specific,  Up: C64DTV-specific

7.3.1 C64DTV ROM image
----------------------

The DTV has a 2MB Flash chip which contains the kernal, basic and
character set ROMs along with other data, such as games in the case of
the original C64DTV ROM.

The image file is a dump of the flash chip. It is exactly 2MB (2097152
bytes).

If you do not have a suitable image file, an image using the C64 kernal,
basic and charset is automatically created.

If writing to the C64DTV ROM is enabled, the image file is rewritten
with the current data when exiting x64dtv.

Note that x64dtv tries to load the image file from the C64DTV directory
first, and if it isn't found there, x64dtv tries to load it from the
current directory. If you do not have `dtvrom.bin' in your C64DTV
directory and writing to DTV ROM is enabled, the `dtvrom.bin' file is
created to the current directory.

NOTE: The original C64DTV ROM has somewhat distorted colors, normally
you should use a patched rom.

`-c64dtvromimage NAME'
     Specify `NAME' as the C64DTV ROM image

`-c64dtvromrw'
`+c64dtvromrw'
     Enable or disable writing to C64DTV ROM image


The trueflashfs option is analogous to True drive emulation.  If
disabled, any file access to the flash filesystem (device 1) will go to
the local file system instead.

`-trueflashfs'
`+trueflashfs'
     Enable or disable true hardware flash file system

`-fsflash NAME'
     Specify `NAME' as directory for flash file system device

7.3.2 DTV revision
------------------

The DTV revision 2 has a bug in the Blitter. Using revision 3 is
recommended. Emulation of DTV revision 2 including Blitter bug is
intended for testing DTV software.

`-dtvrev REVISION'
     Specify DTV `REVISION' (2 or 3)



File: vice.info,  Node: LumaFix,  Next: Userport,  Prev: DTV revision,  Up: C64DTV-specific

7.3.3 LumaFix
-------------

The PAL C64DTVs have wrong resistors in the video output circuit, which
causes incorrect luminances. Several hardware solutions ("LumaFixes")
have been developed to fix this flaw.

The fixed video output is emulated by selecting "New Luminances".  The
unmodified C64DTV video output can be emulated with "Old Luminances".

The default setting is "New Luminances".


File: vice.info,  Node: Userport,  Next: Debug,  Prev: LumaFix,  Up: C64DTV-specific

7.3.4 Userport
--------------

The C64DTV userport emulation currently supports three devices: Hummer
ADC, userport joystick and PS/2 mouse.

The joystick that controls either the Hummer ADC or userport joystick
can be selected using the same parameter or menu option.

While using the Hummer ADC, joystick UP and DOWN are mapped to the
Hummer buttons A and B respectively. LEFT and RIGHT set the ADCs output
to 0 and 255. Centering the joystick results in the ADC value of 128.

Currently the Hummer ADC and userport joystick are mutually exclusive.
This means that enabling one disables the other. PS/2 mouse emulation
can be used simultaneously with either Hummer ADC or userport joystick.

`-hummeradc'
`+hummeradc'
     Enable/Disable Hummer ADC

`-ps2mouse'
`+ps2mouse'
     Enable or disable PS/2 mouse on userport



File: vice.info,  Node: Debug,  Next: Monitor DTV features,  Prev: Userport,  Up: C64DTV-specific

7.3.5 Debug
-----------

Debugging information on Blitter, DMA and Flash can be enabled with
command line parameters. This can be useful for DTV software
development.

`-dtvblitterlog'
`+dtvblitterlog'
     Enable or disable DTV Blitter log

`-dtvdmalog'
`+dtvdmalog'
     Enable or disable DTV DMA log

`-dtvflashlog'
`+dtvflashlog'
     Enable or disable DTV Flash log



File: vice.info,  Node: Monitor DTV features,  Prev: Debug,  Up: C64DTV-specific

7.3.6 Monitor DTV features
--------------------------

Currently the registers A, Y and X are registers R0, R1 and R2
regardless of the mapping, which can be seen and modified via the
registers ACM and XYM.

The monitor can access all 2MB of RAM and 2MB of Flash, but only 64 kB
at a time.  The 64kB bank can be selected with "bank ram00".."ram1f"
for RAM and "bank rom00".."rom1f" for Flash.

The "load" command can load large files (>64kB) correctly if the bank
is set to "ramXX", where XX is the starting bank (usually "bank00").

7.3.7 DTV resources
-------------------

`DtvRevision'
     Integer specifying the emulated DTV revision (2: DTV2, 3: DTV3)

`c64dtvromfilename'
     String specifying the filename of the DTV Flash ROM image.  

`c64dtvromrw'
     Boolean that specifies whether the emulated Flash ROM is writeable.  

`FSFlashDir'
     String specifying the working directory for the flash file system.  

`FlashTrueFS'
     Boolean, enables true hardware flash file system.

`HummerADC'
     Boolean, enables Hummer ADC emulation.

`ps2mouse'
     Boolean, enables PS/2 Mouse emulation.

`DtvBlitterLog'
     Boolean, enables Blitter logging.  

`DtvDMALog'
     Boolean, enables DMA logging.  

`DtvFlashLog'
     Boolean, enables Flash ROM logging.

7.4 VIC20-specific commands and settings
========================================

This section lists the settings and commands that are VIC20-specific and
thus are not present in the other emulators.

* Menu:

* VIC20 cartridges::
* VIC20 memory expansions::
* VIC20 system ROM settings::


File: vice.info,  Node: VIC20 cartridges,  Next: VIC20 memory expansions,  Prev: VIC20-specific,  Up: VIC20-specific

7.4.1 Using cartridge images
----------------------------

As with the C64 (*note C64 cartridges::), it is possible to attach
several types of cartridge images:

   * 4 or 8 Kbyte cartridges located at $2000;

   * 4 or 8 Kbyte cartridges located at $4000;

   * 4 or 8 Kbyte cartridges located at $6000;

   * 4 or 8 Kbyte cartridges located at $A000;

   * 4 Kbyte cartridges located at $B000.

This can all be done via the "Attach cartridge image..." command in the
left-button menu.  It is also possible to let xvic "guess" the type of
cartridge using "Smart-attach cartridge image...".

Notice that several cartridges are actually made up of two pieces (and
two files), that need to be loaded separately at different addresses.
In that case, you have to know the addresses (which are usually
specified in the file name) and use the "attach" command twice.

A special kind of cartridge file is where the two files mentioned above
are concatenated (with removing the two byte load address of the second
image) into one 16k image. There are only few of those images, though.
Normally the second part is located at $A000.  Vice can now attach such
concatenated files at the start address $2000, $4000, and $6000. The
second half of such an image is moved to $A000. If you encounter 16k
images that have the second half not at $A000 you can split the image
into two halfs (i.e. one 8194 byte and one 8192 byte, because the first
has the load address) and attach both files separately.

One cartridge that is currently only partially supported here is the
VIC1112 IEEE488 interface. You have to load the ROM as a cartridge, but
you also have to enable the IEEE488 hardware by menu.

7.4.4 Changing memory configuration
-----------------------------------

It is possible to change the VIC20 memory configuration in two ways: by
enabling and/or disabling certain individual memory blocks, or by
choosing one among a few typical memory configurations.  The former can
be done by modifying resource values directly or from the right-button
menu; the latter can only be done from the menu.

There are 5 RAM expansion blocks in the VIC20, numbered 0, 1, 2, 3 and
5:

   * block 0 (3 Kbytes at $0400-$0FFF);

   * block 1 (8 Kbytes at $2000-$3FFF);

   * block 2 (8 Kbytes at $4000-$5FFF);

   * block 3 (8 Kbytes at $6000-$7FFF);

   * block 5 (8 Kbytes at $A000-$BFFF).

These blocks are called "expansion blocks" because they are not present
a stock ("unexpanded") machine.  Each of them is associated to a
boolean `RamBlockX' resource (where `X' is the block number) that
specifies whether the block is enabled or not.

There are also some common memory configurations you can pick from the
right-button menu:

   * no RAM expansion blocks at all;

   * all RAM expansion blocks enabled;

   * 3K expansion (only block 0 is enabled);

   * 8K expansion (only block 1 is enabled);

   * 16K expansion (only blocks 1 and 2 are enabled);

   * 24K expansion (only blocks 1, 2 and 3 are enabled).

7.4.4.2 VIC20 memory configuration command-line options
.......................................................

`-memory CONFIG'
     Specify memory configuration.  It must be a comma-separated list of
     options, each of which can be one the following:

        * `none' (no extension);

        * `all' (all blocks);

        * `3k' (3k space in block 0);

        * `8k' (first 8k extension block);

        * `16k' (first and second 8k extension blocks);

        * `24k' (first, second and 3rd extension blocks);

        * `0', `1', `2', `3', `5' (memory in respective blocks);

        * `04', `20', `40', `60', `A0' (memory at respective address.

     For example,

     xvic -memory none

     gives an unexpanded VIC20.  While

     xvic -memory 60,a0

     or

     xvic -memory 3,5

     enables memory in blocks 3 and 5, which is the usual configuration
     for 16k ROM modules.

7.6 PET-specific commands and settings
======================================

This section lists the settings and commands that are PET-specific and
thus are not present in the other emulators.

* Menu:

* PET model::
* PET diagnostic pin::
* PET commandline options::
* PET colors::


File: vice.info,  Node: PET model,  Next: PET diagnostic pin,  Prev: PET-specific,  Up: PET-specific

7.6.1 Changing PET model settings
---------------------------------

With `xpet', it is possible to change at runtime the characteristics of
the emulated PET so that it matches (or not) the ones of a certain PET
model, and it is also possible to select from a common set of PET
models so that all the features are selected accordingly.

The former is done by changing the following resources (via resource
file, command line options or right-menu items):

`RamSize'
     Size of memory in kByte. 96k denotes a 8096, 128k a 8296.

`IOSize'
     Size of I/O area in Byte.  Either 2048 or 256 for 8296.

`VideoSize'
     The number of columns on the screen (40 or 80).  A 0 auto-detects
     this from the ROM.

`Ram9'
     The 8296 can map RAM into the address range $9***

`RamA'
     The 8296 can map RAM into the address range $A***

`SuperPET'
     This resource enables the SuperPET (MicroMainFrame 9000) I/O and
     6809 CPU, and disables the 8x96 mappings.

`Basic1'
     If (by checksum) a version 1 kernal is detected, then the kernal
     ROM is patched to make the IEEE488 interface work.

`Basic1Chars'
     Exchanges some character in the character ROM that have changed
     between the first PET 2001 and all newer versions.

`EoiBlank'
     This resource enables the "blank screen on EOI" feature of the
     oldest PET 2001.

`DiagPin'
     Set the diagnositc pin on the PET userport (see below).

`ChargenName'
     Specify `NAME' as the character generator ROM file

`KernalName'
     Specify `NAME' as the kernal ROM file.  This file contains the
     complete BASIC, EDITOR and KERNAL ROMs and is either 16k (BASIC 1
     and 2) or 20k (BASIC 4) in size.

`EditorName'
     Specify `NAME' as the editor ROM file.  This file contains an
     overlay for the editor ROM at $E000-$E7FF if necessary.

`RomModule9Name'
     Specify `NAME' as the $9*** Expansion ROM file.  This file contains
     an expansion ROM image of 4k.

`RomModuleAName'
     Specify `NAME' as the $A*** Expansion ROM file.  This file contains
     an expansion ROM image of 4k.

`RomModuleBName'
     Specify `NAME' as the $B*** Expansion ROM file.  This file contains
     an expansion ROM image of 4k.  This file overlays the lowest 4k of
     a BASIC 4 ROM.


Choosing a common PET model is done from the right-button menu instead,
by choosing an item from the "Model defaults" submenu.  Available
models are:

   * PET 2001-8N

   * PET 3008

   * PET 3016

   * PET 3032

   * PET 3032B

   * PET 4016

   * PET 4032

   * PET 4032B

   * PET 8032

   * PET 8096

   * PET 8296

   * SuperPET

Notice that this will *reset the emulated machine*.

It is also possible to select the PET model at startup, with the
`-model' command-line option: for example, `xpet -model 3032' will
emulate a PET 3032 while `xpet -model 8296' will emulate a PET 8296.

     $0800-$0fff, $1000-$1fff, $2000-$3FFF, $4000-$5FFF, $6000-$7FFF
     and $c000-$cfff respectively.

`Cart1Name'
`Cart2Name'
`Cart4Name'
`Cart6Name'
     Specify `NAME' as the $1000-$1FFF, $2000-$3FFF, $4000-$5FFF or
     $6000-$6FFF Expansion ROM file.  This file contains an 8k ROM dump.

`ModelLine'
     The CBM-II business models have two hardcoded lines at one of the
     I/O ports.  From those lines the kernal determines how it should
     init the CRTC video chip for either 50Hz (Europe) or 60Hz (North
     America), and either for 8 (C6x0) or 14 (C7x0) scanlines per
     character.  0 = CBM 7x0 (50Hz), 1 = 60Hz C6x0, 2 = 50Hz C6x0).


Choosing a common CBM-II model is done from the right-button menu
instead, by choosing an item from the "Model defaults" submenu.
Available models are:

   * C510 (128k RAM)

   * C610 (128k RAM)

   * C620 (256k RAM)

   * C620+ (1024k RAM, expanded)

   * C710 (128k RAM)

   * C720 (256k RAM)

   * C720+ (1024k RAM, expanded)

Notice that this will *reset the emulated machine*.

Warning: At this time switching between 510 and other machines during
runtime is not supported and will not work.

It is also possible to select the CBM model at startup, with the
`-model' command-line option: for example, `xcbm2 -model 610' will
emulate a CBM 610 while `xcbm2 -model 620' will emulate a CBM 620.
Notably this is the only way to start a C510 emulation, with `-model
510'.

8 Snapshots
***********

Every VICE emulator has a built-in snapshot feature, that saves the
complete emulator state into one file for later use.  You can therefore
save the emulator state - including the state of the game you are
playing for example - in a single file.

* Menu:

* Snapshot usage::
* Snapshot format::


File: vice.info,  Node: Snapshot usage,  Next: Snapshot format,  Prev: Snapshots,  Up: Snapshots

8.1 Snapshot usage
==================

A snapshot is one file containining the complete emulator state.  A
snapshot file can be generated by selecting the "Save snapshot" command
at any time.  This will pop up a requester from which you can specify
whether the snapshot should also contain the disk and ROM status.

A snapshot file can be used to restore the emulator state by selecting
the `load snapshot' menu entry at any time.  Unfortunately attached ROM
images/cartridges are only supported in the VIC20, the PET and the
CBM-II emulators at this time.

The memory configuration of the emulator is saved in the snapshot file
as well. This configuration is restored when the snapshot is loaded.

A quick snapshot can now be made by pressing the `M-F11' key and
reloaded by pressing the `M-F10' key.


File: vice.info,  Node: Snapshot format,  Prev: Snapshot usage,  Up: Snapshots

8.2 Snapshot format
===================

A snapshot file consists of several modules of mostly different types.
Each module has a name and saves the state of an entity like a CIA, the
CPU, or the memory.

This section shows the basic module framework and the contents of the
different types of modules.

The single chip modules contain the chip state, not the state of the
emulator.  We tried to make the format as implementation-independent as
possible, to allow reuse of snapshots in later versions of this
emulator, or even in other emulators.

8.2.2.1 Terminology
...................

In this section we use certain abbreviations to define the types of the
data saved in the snapshot.

`BYTE'
     8 bit integer.

`WORD'
     16 bit integer.  Saved with low-byte first, high-byte last.

`DWORD'
     32 bit integer.  Saved with low-word first, then high-word.  Each
     word saved with its low-byte first.

`ARRAY'
     Array of BYTE values.  Length depends on the description.

The tables for the single modules state the type, name and description
of the data saved in the modules.  The data is saved in the order it is
in the tables, so no offset is given.

                                      "C128". zerobyte-padded.

The file header is followed by a number of different snapshot modules.

Each module has a header with the information given in the table below.
The header includes two version numbers, VMAJOR and VMINOR.  Modules
with the same VMAJOR should be able to be exchanged.  I.e. higher VMINOR
numbers only append to the data for lower VMINOR.  This additional data
is ignored by older restore routines.  The other way around newer
restore routines must accept the fewer info from lower VMINOR dumps.
Changes in VMAJOR might introduce any incompatibility you like, but
that's what VMAJOR is for after all :-)

Type    Name                          Description
16 BYTE MODULENAME                    The name of the module in ASCII,
                                      padded with 0 to 16 byte.
BYTE    VMAJOR                        major version number
BYTE    VMINOR                        minor version number
DWORD   SIZE                          size of the module, including this

8.2.2.11 ACIA module
....................

The ACIA 6551 is an RS232 interface chip.  VICE emulates RS232
connections via `/dev/ttyS*' (Unix) or `COM:' (DOS/WIN - not yet?).
When saving a snapshot, those connections are of course lost.  The
state of the ACIA however is restored if possible.  I.e. if a connection
is already open when restoring the snapshot, this connection is used
instead.  If no connection is open, a carrier/DTR drop is emulated.

8.2.2.14 CRTC module
....................

Warning: After VICE version 1.0 the CRTC emulation has improved
considerably. Especially it is now cycle exact. Therefore a lot more
variables must be saved. The snapshot module version jumped from 0.0 to
1.0. Newer versions of VICE can read the old snapshots, but older
versions (1.0 and below) cannot read the new snapshots.

Warning: This module is still under construction.  Especially the
RASTERY and RASTERLINE values might be bogus.

Version numbers: Major 1, Minor 1.

The POSITIONAL item has been added in PETMEM snapshot version 1.1. It is
ignored by earlier restore routines (V1.0) and the V1.1 restore routines
do not change the current setting when reading a V1.0 snapshot.

In V1.2 the new EOIBLANK variable has been added. This implements the
"blank screen on EOI" feature that was previously linked to a wrong
resource.

In V1.3 the state for SuperPET has been added.

8.2.2.19 CBM-II memory module
.............................

The CBM-II memory module actually consists of two modules.  The
"CBM2MEM" module is mandatory and contains the RAM dump.  The "CBM2ROM"
module is optional and contains a dump of the ROM images.

The size of the CBM-II memory modules differs with each different memory
configuration.  The RAM configuration is saved in the snapshot, and
restored when the snapshot is loaded.

Version numbers: Major 1, Minor 0

The RAM* arrays are only saved if the RAM itself is less than 1M.  If
the memory size is 1M then those areas are taken from the bank 15 area
of the normal RAM.

The memory array starts at $10000 if the memory size is less than 512k,
or at $00000 if 512k or more. In case of a C510, then the memory array
also always starts at $00000.

10 Event history
****************

VICE supports recording an arbitrary session on the emulated machine and
playing back this session later. This is done by saving a snapshot at
the beginning of the recording session and then remembering all the
user interaction such as keyboard and joystick input. We call this an
'event history'.  The main purpose for having an event history is to
create game sessions, e.g. recording how to solve a game. An example
walkthrough for the well known game "Fort Apocalypse" is available.

This brief chapter will advise you how to record and playback such a
session.  Although it is based on the WinVICE x64 release and its user
interface, histories may be transferred to other machines and other
ports that support event history, e.g. the Unix port.

10.1 Recommended Settings
=========================

When using the event history feature it is possible that the playback
session differs from what was done at recording time. This might arise
due to a problem in the initial snapshot or settings.  Here are some
suggestions to minimize the chance of failures in the session: a. Reset
to default settings.  b. Choose refresh rate 1/1.  c. Choose joystick
and Video/Doublesize settings as desired or needed.  d. SID engine must
be reSID (which is the default).  e. Choose Drive settings/Idle method:
None Do not change any settings during recording or playback!

10.2 Recorded Events
====================

The following is a list of the user interaction that will be recorded:
- Joystick movement and button - Keyboard - Resetting the machine (hard
and soft) - Attaching or detaching disk/tape images (see 8. Limitations)
- Datasette controls

10.3 Recording an Event History
===============================

Recording an event history will create one or two files for a snapshot
and the list of the user events. First, create an empty directory in
which these files are to be saved and then select this directory and
the name of the snapshot files via 'Snapshot//Select History
files/directory'.  Next, attach the disk or tape image with the game
you want to record and load and run the game.

Start recording via 'Snapshot//Start/Stop Recording History'.  Play the
game. All actions will be recorded.  After the game is finished, stop
recording via 'Snapshot//Start/Stop Recording History'. The selected
directory should now contain the two snapshot files (default ist
start.vsf and end.vsf).

10.4 Setting and Returning to Milestones
========================================

It is difficult to finish a game in one sitting and noone wants to
record all their mistakes and lost lives. Use the milestone feature in a
recording session in the following way:

Set a milestone when you have finished a level or completed a task
('Snapshot//Set recording milestone' or ALT-E). This will save the event
history and a snapshot of the machine to the file end.vsf but recording
will continue.

Return to the last milestone when you have made a mistake or lost a life
('Snapshot//Return to milestone' or ALT-U). This will reset the game
and the event history to the last milestone snapshot so that you can
try again.

10.5 Continuing an Event History
================================

If you have stopped a recording session and want to continue it later,
you should create a backup of your start.vsf and end.vsf files first to
avoid overwriting them by accident.

Then change the event history start mode: 'Snapshot//Recording start
mode//Load existing snapshot'. When you start recording now, you will
continue where the session was stopped last time.

Another way of continuing an existing history is to start somewhere
inside the history (e.g. you have recorded 10 minutes of a game and
later recognize that you made a mistake after 6 minutes that makes it
impossible to finish the game).  For this you have to select the start
mode 'Overwrite playback'. Now you can start the playback with
'Snapshot//Start/Stop Playback History' and when you reach the point
where you want to change the history you can directly switch to
recording via 'Snapshot//Start/Stop Recording History'.

10.6 Playing Back an Event History
==================================

To play back an event history, select the directory with the history
files start.vsf and end.vsf via 'Snapshot//Select History directory'
and start the playback with 'Snapshot//Start/Stop Playback History'.
Enjoy!  During playback any user interaction is disabled.  The playback
stops when the end of the session is reached or if 'Snapshot//Select
History directory' is selected again.

10.7 Limitations and Suggestions
================================

a. Snapshot files will be quite big (>1MB) if a disk image has been
attached.  If possible, use PRG or T64 images to reduce the size of
snapshot files.  b. Snapshots may not be 100% accurate even with all
the recommended settings.

10.8 Event history resources
============================

`EventSnapshotDir'
     String specifying the directory used for loading and saving
     snapshots.  

`EventStartSnapshot'
     String specifying the filename for the start snapshot.
     ["start.vsf"] 

`EventEndSnapshot'
     String specifying the filename for the end snapshot. ["end.vsf"] 

`EventStartMode'
     Integer specifying how to start event recording. (0: save new
     snapshot, 1: load existing snapshot, 2: reset, 3: playback) 

`EventImageInclude'
     Boolean specifying whether to include ROM and Disk images in the
     snapshots. [1]

11 Monitor
**********

Every VICE emulator has a complete built-in monitor, which can be used
to examine, disassemble and assemble machine language programs, as well
as debug them through breakpoints.  It can be activated by using the
"Activate monitor" command (left button menu).  Notice that you have to
run the emulator from a terminal emulation program (such as `rxvt' or
`xterm') in order to use the monitor.

Warning: this version of the monitor is still under construction, and
some of the features are not fully working yet.

File: vice.info,  Node: Terminology,  Next: Machine state commands,  Prev: Monitor,  Up: Monitor

11.1 Terminology
================

`address_space'
     This refers to the range of memory locations and a set of
     registers.  This can be the addresses available to the computer's
     processor, the disk drive's processor or a specific memory
     configuration of one of the mentioned processors.

`bankname'
     The CPU can only see 64k of memory at any one time, due to its 16
     bit address bus. The C64 and other computers have more than this
     amount, and this is handled by banking: a memory address can have
     different contents, depending on the active memory bank.  A
     bankname names a specific bank in the current address_space.

`register'
     One of the following: program counter (PC), stack pointer (SP),
     accumulator (A), X register (X), or Y register (Y).

`address'
     A specific memory location in the range $0000 to $FFFF.

`address_range'
     Two addresses.  If the second address is less than the first, the
     range is assumed to wraparound from $FFFF to $0000.  Both addresses
     must be in the same address space.

`address_opt_range'
     An address or an address range.

`label'
     `label' is the name of a label. it must start with a dot (".")  in
     order for the monitor to recognize it as a label.

`prompt'
     The prompt has the format [x:y].  If x is -, memory reads from the
     monitor do not have side effects.  Otherwise, x is S.  The second
     part of the prompt, y, shows the default address space.

`checkpoint'
     The monitor has the ability to setup triggers that perform an
     action when a specified situation occurs.  There are three types of
     checkpoints; breakpoints, tracepoints and watchpoints.

`breakpoint'
     A breakpoint is triggered based on the program counter.  When it is
     triggered, the monitor is entered.

`tracepoint'
     Like breakpoints, a tracepoint is triggered based on the program
     counter.  Instead of entering the monitor, the program counter is
     printed and execution continues.

`watchpoint'
     Watchpoints are triggered by a read and/or write to an address.
     When a watchpoint is triggered, the monitor is entered.

`memmap'
     The memmap keeps track of RAM/ROM/IO read/write/execute accesses.
     The feature must be enabled with "-enable-memmap" configure
     option, as it might decrease performance notably on slower
     hardware. The option also enables CPU history.

`<...>'
     A data type.

`*'
     Zero or more occurrences.

`[...]'
     An optional argument.



File: vice.info,  Node: Machine state commands,  Next: Memory commands,  Prev: Terminology,  Up: Monitor

11.2 Machine state commands
===========================

`backtrace'
`bt'
     Print JSR call chain (most recent call first). Stack offset
     relative to SP+1 is printed in parentheses. This is a best guess
     only.

`cpuhistory [<count>]'
`chis [<count>]'
     Show <count> last executed commands.  (disabled by default;
     configure with -enable-memmap to enable)

`dump "<filename>"'
     Write a snapshot of the machine into the file specified.  This
     snapshot is compatible with a snapshot written out by the UI.
     Note: No ROM images are included into the dump.

`goto <address>'
`g <address>'
     Change the PC to address and continue execution.

`io [<address>]'
     Display i/o registers. Invoking without an address shows a dump of

     chip at the respective (base-)address are displayed (if available).

`next [<count>]'
`n [<count>]'
     Advance to the next instruction.  Subroutines are treated as a
     single instruction.

`registers [<reg_name> = <number> [, <reg_name> = <number>]*]'
`r [<reg_name> = <number> [, <reg_name> = <number>]*]'
     Assign respective registers.  With no parameters, display register
     values.

`reset [<type>]'

     drive.

`return'
`ret'
     Continues execution  and returns to the monitor just after the
     next RTS or RTI is executed.

`step [<count>]'
`z [<count>]'
     Single step through instructions.  An optional count allows
     stepping more than a single instruction at a time.

`stopwatch [reset]'
     Print the CPU cycle counter of the current device. 'reset' sets
     the counter to 0.

11.3 Memory commands
====================

`bank [<bankname>]'
     Without a bankname, display all available banks for the current
     address_space. With a bankname given, switch to the specified
     bank. If a bank is not completely filled (ROM banks for example)
     normally the `ram' bank is used where the bank has holes.  The
     `cpu' bank uses the bank currently used by the CPU.

`compare <address_range> <address>'
`c <address_range> <address>'
     Compare memory from the source specified by the address range to
     the destination specified by the address.  The regions may
     overlap.  Any values that miscompare are displayed using the
     default displaytype.

`device [c:|8:|9:]'
     Set the default address space to either the computer `c:' or the
     specified drive `8:' or `9:'

`fill <address_range> <data_list>'
`f <address_range> <data_list>'
     Fill memory in the specified address range with the data in
     <data_list>.  If the size of the address range is greater than the
     size of the data_list, the data_list is repeated.

`hunt <address_range> <data_list>'
`h <address_range> <data_list>'
     Hunt memory in the specified address range for the data in
     <data_list>.  If the data is found, the starting address of the
     match is displayed.  The entire range is searched for all possible
     matches.  The data list may have `xx' as a wildcard.

`i <address_opt_range>'
     Display memory contents as PETSCII text.

`ii <address_opt_range>'
     Display memory contents as screen code text

`mem [<data_type>] [<address_opt_range>]'
`m [<data_type>] [<address_opt_range>]'
     Display the contents of memory.  If no datatype is given, the
     default is used.  If only one address is specified, the length of
     data displayed is based on the datatype.  If no addresses are
     given, the 'dot' address is used.

`memmapshow [<mask>] [<address_opt_range>]'
`mmsh [<mask>] [<address_opt_range>]'
     Show the memmap. The mask can be specified to show only those
     locations with accesses of certain type(s). The mask is a number
     with the bits "ioRWXrwx", where RWX are for ROM and rwx for RAM.
     Optionally, an address range can be specified.  (disabled by
     default; configure with -enable-memmap to enable)

`memmapzap'
`mmzap'
     Clear the memmap.  (disabled by default; configure with
     -enable-memmap to enable)

`memmapsave "<filename>" <format>'
`mmsave "<filename>" <format>'
     Save the memmap as a picture. `format': 0 = BMP, 1 = PCX, 2 = PNG,
     3 = GIF, 4 = IFF.  (disabled by default; configure with
     -enable-memmap to enable)

`memchar [<data_type>] [<address_opt_range>]'
`mc [<data_type>] [<address_opt_range>]'
     Display the contents of memory as character data.  If only one
     address is specified, only one character is displayed.  If no
     addresses are given, the "dot" address is used.

`memsprite [<data_type>] [<address_opt_range>]'
`ms [<data_type>] [<address_opt_range>]'
     Display the contents of memory as sprite data.  If only one
     address is specified, only one sprite is displayed.  If no
     addresses are given, the "dot" address is used.

`move <address_range> <address>'
`t <address_range> <address>'
     Move memory from the source specified by the address range to the
     destination specified by the address.  The regions may overlap.

`screen'
`sc'
     Displays the contents of the screen.

`sidefx [on|off|toggle]'
`sfx [on|off|toggle]'
     Control how monitor generated reads affect memory locations that
     have read side-effects, like CIA interrupt registers for example.
     If the argument is 'on' then reads may cause side-effects.  If the
     argument is 'off' then reads don't cause side-effects.  If the
     argument is 'toggle' then the current mode is switched.  No
     argument displays the current state.

`> [<address>] <data_list>'
     Write the specified data at `address'.



File: vice.info,  Node: Assembly commands,  Next: Checkpoint commands,  Prev: Memory commands,  Up: Monitor

11.4 Assembly commands
======================

`a <address> [ <instruction> [: <instruction>]* ]'
     Assemble instructions to the specified address.  If only one
     instruction is specified, enter assembly mode (enter an empty line
     to exit assembly mode).

`disass [<address> [<address>]]'
`d [<address> [<address>]]'
     Disassemble instructions.  If two addresses are specified, they are
     used as a start and end address.  If only one is specified, it is
     treated as the start address and a default number of instructions
     are disassembled.  If no addresses are specified, a default number
     of instructions are disassembled from the dot address.



File: vice.info,  Node: Checkpoint commands,  Next: General commands,  Prev: Assembly commands,  Up: Monitor

11.5 Checkpoint commands
========================

`break [load|store|exec] [address [address] [if <cond_expr>]]'
     This command allows setting a breakpoint or listing the current
     breakpoints.  If no address is given, the currently valid
     checkpoints are printed.  If an address is given, a breakpoint is
     set for that address and the breakpoint number is printed.  The
     "load|store|exec" parameter can be either "load", "store" or "exec"
     (or any combination of these) to determine on which operation the
     monitor breaks. If not specified, the monitor breaks on "exec".  A
     conditional expression can also be specified for the breakpoint.
     For more information on conditions, see the CONDITION command.

`enable <checknum>'

`disable <checknum>'
     Each checkpoint can be enabled or disabled.  This command allows
     changing between these states.

`command <checknum> "<command>"'
     When checkpoint `checknum' is hit, the specified command is
     executed by the monitor.  Note that the `x' command is not yet
     supported as a command argument.

`condition <checknum> if <cond_expr>'
`cond <checknum> if <cond_expr>'
     Each time the specified checkpoint is examined, the condition is
     evaluated.  If it evalutes to true, the checkpoint is activated.
     Otherwise, it is ignores.  If registers are specified in the
     expression, the values used are those at the time the checkpoint is
     examined, not when the condition is set.

     Currently, the cond_expr is very limited. You can use registers
     (.A, .X, .Y, .PC, and .SP) and compare against other registers or
     absolute values. For example, the following are all valid
     conditions: .A == 0, .X == .Y, 8:.X == .X, .A != 5, .A < .X.

     However, you cannot specify memory contents and compare that.

`delete <checknum>'
`del <checknum>'
     Delete the specified checkpoint.

`ignore <checknum> [<count>]'
     Ignore a checkpoint after a given number of crossings.  If no
     count is given, the default value is 1.

`trace [load|store|exec] [address [address] [if <cond_expr>]]'
`tr [load|store|exec] [address [address] [if <cond_expr>]]'
     This command is similar to the `break' command except that it
     operates on tracepoints.  A tracepoint differs from a breakpoint by
     not stopping execution but simply printing the PC, giving the user
     an execution trace.  The second optional address can be used to
     specify the end of an range of addresses to be traced.  If no
     addresses are given, a list of all the checkpoints is printed.
     The "load|store|exec" parameter can be either "load", "store" or
     "exec" (or any combination of these) to determine which operation
     the monitor traces. If not specified, the monitor traces all
     operations.  A conditional expression can also be specified for
     the tracepoint.  For more information on conditions, see the
     CONDITION command.

`until [<address>]'
`un [<address>]'
     If no address is given, the currently valid breakpoints are
     printed.  If an address is given, a temporary breakpoint is set
     for that address and the breakpoint number is printed.  Control is
     returned to the emulator by this command.  The breakpoint is
     deleted once it is hit.

`watch [load|store|exec] [address [address] [if <cond_expr>]]'
`w [load|store|exec] [address [address] [if <cond_expr>]]'
     This command is similar to the `break' command except that it
     operates on watchpoints.  A watchpoint differs from a breakpoint by
     stopping on a read and/or write to an address or range of
     addresses.  If no addresses are given, a list of all the
     checkpoints is printed.  The "load|store|exec" parameter can be
     either "load", "store" or "exec" (or any combination of these) to
     determine on which operation the monitor breaks. If not specified,
     the monitor breaks on "load" and "store" operations.  A
     conditional expression can also be specified for the watchpoint.
     For more information on conditions, see the CONDITION command.

`l "<filename>" <device> [<address>]'
     Load the specified file into memory.  If no address is given, the
     file is loaded to the address specified by the first two bytes
     read from the file.  If address is given, the file is loaded to
     the specified address and the first two bytes read from the file
     are skipped.  If device is 0, the file is read from the file
     system.

`list [<directory>]'
     List disk contents.

`bload "<filename>" <device> <address>'
`bl "<filename>" <device> <address>'

`s "<filename>" <device> <address1> <address2>'
     Save the memory from address1 to address2 to the specified file.
     Write two-byte load address.  If device is 0, the file is written
     to the file system.

`bsave "<filename>" <device> <address1> <address2>'
`bs "<filename>" <device> <address1> <address2>'
     Save the memory from address1 to address2 to the specified file.
     If device is 0, the file is written to the file system.

11.8 Command file commands
==========================

`playback "<filename>"'
`pb "<filename>"'
     Monitor commands from the specified file are read and executed.
     This command stops at the end of file or when a STOP command is
     read.

`record "<filename>"'
`rec "<filename>"'
     After this command, all commands entered are written to the
     specified file until the STOP command is entered.

`stop'
     Stop recording commands.  See `record'.



File: vice.info,  Node: Label commands,  Next: Miscellaneous commands,  Prev: Command file commands,  Up: Monitor

11.9 Label commands
===================

`add_label <address> <label>'
`al <address> <label>'
     Map a given address to a label.  This label can be used when
     entering assembly code and is shown during disassembly.
     Additionally, it can be used whenever an address must be specified.

     <label> is the name of the label; it must start with a dot (".") in
     order for the monitor to recognize it as a label.

`delete_label [<memspace>] <label>'
`dl [<memspace>] <label>'
     Remove the specified label from the label tables.  If no memory
     space is checked, all tables are checked.

`load_labels [<memspace>] "<filename>"'
`ll [<memspace>] "<filename>"'
     Load a file containing a mapping of labels to addresses.  If no
     memory space is specified, the default readspace is used.

     The file must contain commands the monitor understands, e.g.
     add_label. The compiler cc65 can create such label files.

     Vice can also load label files created by the Acme assembler.
     Their syntax is e.g. "labelname = $1234 ; Maybe a comment". A dot
     will be added automatically to label names assigned in this way to
     fit to the Vice label syntax. Normally the semicolon seperates
     commands but after an assignment of this kind it may be used to
     start a comment to end of line, so unchanged Acme label files can
     be fed into Vice.

`save_labels [<memspace>] "<filename>"'
`sl [<memspace>] "<filename>"'
     Save labels to a file.  If no memory space is specified, all of the
     labels are saved.

`show_labels [<memspace>]'
`shl [<memspace>]'
     Display current label mappings.  If no memory space is specified,
     show all labels.

12 c1541
********

VICE is provided with a complete stand-alone disk image maintenance
utility, called `c1541'.

You can either invoke it from the command line or from within one of
the VICE emulators, using the "Run c1541" command which will open a new
`xterm' window with a running `c1541' in it.

The syntax is:

c1541 [IMAGE1 [IMAGE2]] [COMMAND1 COMMAND2 ... COMMANDN]

`IMAGE1' and `IMAGE2' are disk image names that can be attached before
`c1541' starts.  `c1541' can handle up to two disk images at the same
time by using two virtual built-in drives, numbered `8' and `9';
`IMAGE1' (if present) is always attached to drive `8', while `IMAGE2'
is attached to drive `9'.

`COMMAND's specified on the command-line all begin with the minus sign
(`-'); if present, `c1541' executes them in the same order as they are
on the command line and returns a zero error code if they were
successful.  If any of the `COMMAND's fails, `c1541' stops and returns
a nonzero error code.

If no `COMMAND's are specified at all, `c1541' enters interactive mode,
where you can type commands manually.  Commands in interactive mode are
the same as commands in batch mode, but do not require a leading `-'.
As with the monitor, file name completion and command line editing with
history are provided via GNU `readline'.  Use the command `quit' or
press `C-d' to exit.

12.1 Specifying files in c1541
==============================

When accessing CBM DOS files (i.e. files that reside on disk images),
c1541 uses a special syntax that lets you access files on both drive 8
and 9.  If you prepend the file name with `@8:' or `@9:', you will
specified that file is to be found or created on drive 8 and 9,
respectively.

For instance,

@8:somefile

will name file named `somefile' on unit 8, while

@9:somefile

will name file named `somefile' on unit 9.


File: vice.info,  Node: c1541 quoting,  Next: c1541 commands and options,  Prev: c1541 file specification,  Up: c1541

12.2 Using quotes and backslashes
=================================

You can use quotes (`"') in a command to embed spaces into file names.
For instance,

read some file

will read file `some' from the disk image and write it into the file
system as `file', while

read "some file"

will copy `some file' into the file system, with the name `some file'.

The backslash character (`\') has a special meaning too: it lets you
literally insert the following character no matter what it is.  For
example,

read some\ file

will copy file `some file' into the file system, while

read some\ file this\"file

will copy `some file' into the file system with name `this"file' (with
an embedded quote).

12.3 c1541 commands and options
===============================

This is a list of the `c1541' commands.  They are shown in their
interactive form, without the leading `-'.  Square brackets [] indicate
an optional part, and "<COMMAND>" translates to a disk command
according to CBM DOS, like "i0" for example.

     and `imagename' are specified, create a new image named
     `imagename', attach it to unit 8 and format it.  `type' is a disk
     image type, and must be either `x64', `d64' (both VC1541/2031),
     `g64' (VC1541/2031 but in GCR coding), `d71' (VC1571), `d81'
     (VC1581), `d80' (CBM8050) or `d82' (CBM8250/1001).  Otherwise,

12.4 Executing shell commands
=============================

If you want to execute a shell command from withing `c1541', just
prepend it with an exclamation mark (`!').  For example,

!ls -la

will execute the command `ls -la', which will show you all the files in
the current directory.

12.5 c1541 examples
===================

`c1541 -attach test.d64 -write test.prg testfile'
     Write `test.prg' to `test.d64' as `testfile'.

13 cartconv
***********

The cartconv program is a cartridge conversion utility, it can convert
between binary and .crt images and it can 'insert' binary and/or .crt
images into the EPROM type of cartridges.

13.1 cartconv command line options
==================================

The cartconv program has the following parameters:

`-i "input name"'
     This parameter is mandatory, it should contain the name of the
     binary/.crt file you want to convert. For the EPROM type of
     cartridges this parameter can be used multiple times to insert
     images into the resulting file.  

`-o "output name"'
     This parameter is mandatory, it should contain the name of the
     binary/.crt file you want to convert the input file to.  

`-t carttype'
     This parameter is optional. It is only needed when converting to a

15.2 The G64 GCR-encoded disk image format
==========================================

(This section was contributed by Peter Schepers and slightly edited by
Ettore Perazzoli.)

This format was defined in 1998 as a cooperative effort between several
emulator people, mainly Per Håkan Sundell, author of the CCS64 C64
emulator, Andreas Boose of the VICE CBM emulator team and Joe
Forster/STA, the author of Star Commander.  It was the first real public
attempt to create a format for the emulator community which removed
almost all of the drawbacks of the other existing image formats, namely
`D64'.

The intention behind `G64' is not to replace the widely used `D64'
format, as `D64' works fine with the vast majority of disks in
existence.  It is intended for those small percentage of programs which
demand to work with the 1541 drive in a non-standard way, such as
reading or writing data in a custom format.  The best example is with
speeder software such as Action Cartridge in Warp Save mode or Vorpal
which write track/sector data in another format other than standard
GCR.  The other obvious example is copy-protected software which looks
for some specific data on a track, like the disk ID, which is not
stored in a standard `D64' image.

`G64' has a deceptively simply layout for what it is capable of doing.
We have a signature, version byte, some predefined size values, and a
series of offsets to the track data and speed zones.  It is what's
contained in the track data areas and speed zones which is really at the
heart of this format.

Each track entry in simply the raw stream of GCR data, just what a read
head would see when a diskette is rotating past it.  How the data gets
interpreted is up to the program trying to access the disk.  Because the
data is stored in such a low-level manner, just about anything can be
done.  Most of the time I would suspect the data in the track would be
standard sectors, with SYNC, GAP, header, data and checksums.  The
arrangement of the data when it is in a standard GCR sector layout is
beyond the scope of this document.

Since it is a flexible format in both track count and track byte size,
there is no "standard" file size.  However, given a few constants like
42 tracks and halftracks, a track size of 7928 bytes and no speed offset
entries, the typical file size will a minimum of 333744 bytes.

Below is a dump of the header, broken down into its various parts.
After that will be an explanation of the track offset and speed zone
offset areas, as they demand much more explanation.

Addr  00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
----  -----------------------------------------------
0000: 47 43 52 2D 31 35 34 31 00 54 F8 1E .. .. .. ..

Offset         Description
$0000-0007     File signature (`GCR-1541')
$0008          `G64' version (presently only $00 defined)
$0009          Number of tracks in image (usually $54, decimal 84)
$000A-000B     Size of each stored track in bytes (usually 7928, or
               $1EF8) in LO/HI format.

An obvious question here is "why are there 84 tracks defined when a
normal `D64' disk only has 35 tracks?"  Well, by definition, this image
includes all half-tracks, so there are actually 42 tracks and 42 half
tracks.  The 1541 stepper motor can access up to 42 tracks and the
in-between half-tracks.  Even though using more than 35 tracks is not
typical, it was important to define this format from the start with what
the 1541 is capable of doing, and not just what it typically does.

At first, the defined track size value of 7928 bytes may seem to be
arbitrary, but it is not.  It is determined by the fastest write speed
possible (speed zone 0), coupled with the average rotation speed of the
disk (300 rpm).  After some math, the answer that actually comes up is
7692 bytes.  Why the discrepency between the actual size of 7692 and the
defined size of 7928? Simply put, not all drives rotate at 300 rpm.
Some can be faster or slower, so a upper safety margin of +3% was built
added, in case some disks rotate slower and can write more data.  After
applying this safety factor, and some rounding-up, 7928 bytes per track
was arrived at.

Also note that this upper limit of 7928 bytes per track really only
applies to 1541 and compatible disks.  If this format were applied to
another disk type like the SFD1001, this value would be higher.

Below is a dump of the first section of a `G64' file, showing the
offsets to the data portion for each track and half-track entry.
Following that is a dump of the speed zone offsets.

Starting here at $02AC is the first track entry (from above, it is the
first entry for track 1.0)

The track offsets (from above) require some explanation.  When one is
set to all 0's, no track data exists for this entry.  If there is a
value, it is an absolute reference into the file (starting from the
beginning of the file).  From the track 1.0 entry we see it is set for
$000002AC.  Going to that file offset, here is what we see...

Following the track data is filler bytes.  In this case, there are 368
bytes of unused space.  This space can contain anything, but for the
sake of those wishing to compress these images for storage, they should
all be set to the same value.  In the sample I used, these are all set
to $FF.

Below is a dump of the end of the track 1.0 data area.  Note the actual
track data ends at address $20B9, with the rest of the block being
unused, and set to $FF.

The speed offset entries can be a little more complex. The 1541 has four
speed zones defined, which means the drive can write data at four
distinct speeds.  On a normal 1541 disk, these zones are as follows:

Track Range                          Speed Zone
1-17                                 3  (highest writing speed)
18-24                                2
25-30                                1
31 and up                            0 (lowest writing speed)

Note that you can, through custom programming of the 1541, change the
speed zone of any track to something different (change the 3 to a 0) and
write data differently.  From the dump of the speed offset entries
above, we see that all the entries are in the range of 0-3. If any entry
is less than 4, this is not considered a speed offset but defines the
whole track to be recorded at that one speed.

In the example I had, there were no offsets defined, so no speed zone
dump can be shown.  However, I can define what should be there.  You
will have a block of data, 1982 bytes long.  Each byte is encoded to
represent the speed of 4 bytes in the track offset area, and is broken
down as follows:

Speed entry $FF:  in binary %11111111
                             |'|'|'|'
                             | | | |
                             | | | +- 4'th byte speed (binary 11, 3 dec)
                             | | +--- 3'rd byte speed (binary 11, 3 dec)
                             | +----- 2'nd byte speed (binary 11, 3 dec)
                             +------- 1'st byte speed (binary 11, 3 dec)

It was very smart thinking to allow for two speed zone settings, one in
the offset block and another defining the speed on a per-byte basis.  If
you are working with a normal disk, where each track is one constant
speed, then you don't need the extra blocks of information hanging
around the image, wasting space.

What may not be obvious is the flexibility of this format to add tracks
and speed offset zones at will.  If a program decides to write a track
out with varying speeds, and no speed offset exist, a new block will be
created by appending it to the end of the image, and the offset pointer
for that track set to point to the new block.  If a track has no offset
yet, meaning it doesn't exist (like a half-track), and one needs to be
added, the same procedure applies.  The location of the actual track or
speed zone data is not important, meaning they do not have to be in any
particular order since they are all referenced by the offsets at the
beginning of the image.

All initial model state values are initialized with zero.

All initial model probability values are initialized with 2048.

These model probability values will be updating in a adaptive way on the
fly and not precalculated before the encoding and even not loaded before
the decoding, see pseudo code below.

16000000 Hz / 5 rotations per second at 300 RPM = maximal 3200000 flux
pulses

So NRZI transition flux pulse positions are in the 0 .. 3199999 value
range, which is also a exact single rotation, where each time unit is a
cycle at 16 MHz with 300 RPM as a mapping for the ideal case.

The NRZI transition flux pulse stength are in the 0x00000000 ..
0xffffffff value range, where 0xffffffff indices a strong flux pulse,
that always triggers, and 0x00000001 indices a weak flux pulse, that
almost never triggers, and 0x00000000 indices a flux pulse, that
absolutly never triggers.

For 32-bit values, the model sub streams are subdivided byte wide in a
little-endian manner, and each byte is processed bitwise with model
probability shifting of 4 bits, just as:

Pascal-Style pseudo code:
procedure WriteDWord(Model, Value : longword);
var ByteValue, ByteIndex, Context, Bit : longword;
begin
  for ByteIndex := 0 to 3 do begin
    ByteValue := (Value shr (ByteIndex shl 3)) and $ff;
    Context := 1;
    for Bit := 7 downto 0 do begin
      Context := (Context shl 1) or RangeCoderEncodeBit(
                    RangeCoderProbabilities[
                     RangeCoderProbabilityOffsets[Model + ByteIndex] +
                     (((RangeCoderProbabilityStates[Model + ByteIndex]
                     shl 8) or Context) and $ffff)], 4, (ByteValue shr
                     Bit) and 1);
    end;
    RangeCoderProbabilityStates[Model+ByteIndex] := ByteValue;
  end;
end;

And for 1-bit flag values it is much simpler, but also with model
probability shifting of 4 bits, just as:

Pascal-Style pseudo code:
procedure WriteBit(Model, Value : longword);
begin
   RangeCoderProbabilityStates[Model] :=
     RangeCoderEncodeBit(RangeCoderProbabilities[
       RangeCoderProbabilityOffsets[Model] +
         RangeCoderProbabilityStates[Model]], 4, Value and 1);
end;

The position and strength values are delta-encoded. If a value is equal
to the last previous value, then the value will not encoded, instead, a
flag for this will encoded. First the position value will encoded, then
the stength value. If the last position delta is 0, then it is a track
stream end marker.

Pascal-Style pseudo code:
LastPosition := 0;
PreviousDeltaPosition := 0

LastStrength := 0;

for PulseIndex := 0 to PulseCount - 1 do begin

  DeltaPosition := Pulses[PulseIndex].Position - LastPosition;
  if PreviousDeltaPosition <> DeltaPosition then begin
    PreviousDeltaPosition := DeltaPosition;
    WriteBit(ModelPositionFlag, 1)
    WriteDWord(ModelPosition, DeltaPosition);
  end else begin
    WriteBit(ModelPositionFlag, 0);
  end;
  LastPosition := Pulses[PulseIndex].Position;

  if LastStrength <> Pulses[PulseIndex].Strength then begin
    WriteBit(ModelStrengthFlag, 1)
    WriteDWord(ModelStrength, Pulses[PulseIndex].Strength - LastStrength);
  end else begin
    WriteBit(ModelStrengthFlag, 0);
  end;
  LastStrength := Pulses^[PulseIndex].Strength;

end;

// End code
WriteBit(ModelPositionFlag, 1);
WriteDWord(ModelPosition, 0);

The decoding is simply just in the another direction way.

Pseudo code for a FPAQ0-style carryless range coder:

Pascal-Style pseudo code:
procedure RangeCoderInit; // At encoding and decoding start
begin
  RangeCode := 0;
  RangeLow := 0;
  RangeHigh := $ffffffff;
end;

procedure RangeCoderStart; // At decoding start
var Counter : longword;
begin
  for Counter := 1 to 4 do begin
   RangeCode := (RangeCode shl 8) or ReadByteFromInput;
  end;
end;

procedure RangeCoderFlush; // At encoding end
var Counter : longword;
begin
  for Counter := 1 to 4 do begin
    WriteByteToOutput(RangeHigh shr 24);
    RangeHigh := RangeHigh shl 8;
  end;
end;

procedure RangeCoderEncodeNormalize;
begin
  while ((RangeLow xor RangeHigh) and $ff000000) = 0 do begin
   WriteByteToOutput(RangeHigh shr 24);
   RangeLow := RangeLow shl 8;
   RangeHigh := (RangeHigh shl 8) or $ff;
  end;
end;

function RangeCoderEncodeBit(var Probability : longword; Shift,
                             BitValue : longword) : longword;
begin
  RangeMiddle := RangeLow + (((RangeHigh - RangeLow) shr 12) *
                              Probability);
  if BitValue <> 0 then begin
    inc(Probability, ($fff - Probability) shr Shift);
    RangeHigh := RangeMiddle;
  end else begin
    dec(Probability, Probability shr Shift);
    RangeLow := RangeMiddle + 1;
  end;
  RangeCoderEncodeNormalize;
  result := BitValue;
end;

procedure RangeCoderDecodeNormalize;
begin
  while ((RangeLow xor RangeHigh) and $ff000000) = 0 do begin
    RangeLow := RangeLow shl 8;
    RangeHigh := (RangeHigh shl 8) or $ff;
    RangeCode := (RangeCode shl 8) or ReadByteFromInput;
  end;
end;

function RangeCoderDecodeBit(var Probability : longword;
                             Shift : longword) : longword;
begin
  RangeMiddle := RangeLow + (((RangeHigh - RangeLow) shr 12) *
                             Probability);
  if RangeCode <= RangeMiddle then begin
    inc(Probability, ($fff - Probability) shr Shift);
    RangeHigh := RangeMiddle;
    result := 1;
  end else begin
    dec(Probability, Probability shr Shift);
    RangeLow := RangeMiddle + 1;
    result := 0;
  end;
  RangeCoderDecodeNormalize;
end;

The probability may be never zero! But that can't happen here with this
adaptive model in this P64 file format, since the adaptive model uses a
shift factor of 4 bits and initial probabilities value of 2048, so the
probability has a value range from 15 up to 4080 here. If you do want
to use the above range coder routines for other stuff with other
probability models, then you must to ensure that the probability output
value is never zero, for example with  "probability |= (probability <
1); " in C.

15.4 The D64 disk image format
==============================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

First and foremost we have D64, which is basically a sector-for-sector
copy of a 1540/1541 disk. There are several versions of these which I
will cover shortly. The standard D64 is a 174848 byte file comprised of
256 byte sectors arranged in 35 tracks with a varying number of sectors
per track for a total of 683 sectors. Track counting starts at 1, not
0, and goes up to 35. Sector counting starts at 0, not 1, for the first
sector, therefore a track with 21 sectors will go from 0 to 20.

The original media (a 5.25" disk) has the tracks laid out in circles,
with track 1 on the very outside of the disk (closest to the sides) to
track 35 being on the inside of the disk (closest to the inner hub
ring).  Commodore, in their infinite wisdom, varied the number of
sectors per track and data densities across the disk to optimize
available storage, resulting in the chart below. It shows the
sectors/track for a standard D64. Since the outside diameter of a
circle is the largest (versus closer to the center), the outside tracks

(*) Tracks 36-40 apply to 40-track images only.

The directory track should be contained totally on track 18. Sectors
1-18 contain the entries and sector 0 contains the BAM (Block
Availability Map) and disk name/ID. Since the directory is only 18
sectors large (19 less one for the BAM), and each sector can contain
only 8 entries (32 bytes per entry), the maximum number of directory
entries is 18 * 8 = 144. The first directory sector is always 18/1,
even though the t/s pointer at 18/0 (first two bytes) might point
somewhere else. It then follows the same chain structure as a normal
file, using a sector interleave of 3. This makes the chain links go
18/1, 18/4, 18/7 etc.

Note that you can extend the directory off of track 18, but only when
reading the disk or image. Attempting to write to a directory sector
not on track 18 will cause directory corruption. Each directory sector
has the following layout (18/1 partial dump):

 00: 12 04 81 11 00 4E 41 4D 45 53 20 26 20 50 4F 53 <- notice the T/S link
 10: 49 54 A0 A0 A0 00 00 00 00 00 00 00 00 00 15 00 <- to 18/4 ($12/$04)
 20: 00 00 84 11 02 41 44 44 49 54 49 4F 4E 41 4C 20 <- and how its not here
 30: 49 4E 46 4F A0 11 0C FE 00 00 00 00 00 00 61 01 <- ($00/$00)

The first two bytes of the sector ($12/$04) indicate the location of
the next track/sector of the directory (18/4). If the track is set to
$00, then it is the last sector of the directory. It is possible,
however unlikely, that the directory may *not* be competely on track 18
(some disks do exist like this). Just follow the chain anyhow.

When the directory is done, the track value will be $00. The sector
link should contain a value of $FF, meaning the whole sector is
allocated, but the actual value doesn't matter. The drive will return
all the available entries anyways.

This is a breakdown of a standard directory sector:

Bytes          Description
$00-$1F        First directory entry
$20-$3F        Second dir entry
$40-$5F        Third dir entry
$60-$7F        Fourth dir entry
$80-$9F        Fifth dir entry
$A0-$BF        Sixth dir entry
$C0-$DF        Seventh dir entry
$E0-$FF        Eighth dir entry

This is a breakdown of a standard directory entry:

Bytes          Description
$00-$01        Track/Sector location of next directory sector ($00 $00
               if not the first entry in the sector)
$02            File type
$03-$04        Track/sector location of first sector of file
$05-$14        16 character filename (in PETASCII, padded with $A0)
$15-$16        Track/Sector location of first side-sector block (REL
               file only)
$17            REL file record length (REL file only, max. value 254)
$18-$1D        Unused (except with GEOS disks)
$1E-$1F        File size in sectors, low/high byte order ($1E+$1F*256).
               The approx. filesize in bytes is <= #sectors * 254

The file type field is used as follows:

Bits           Description
0-3            The actual file type
4              Unused
5              Used only during SAVE-@ replacement
6              Locked flag (Set produces ">" locked files)
7              Closed flag (Not set produces "*", or "splat" files)

The actual file type can be one of the following:

Binary         Decimal        File type
0000           0              DEL
0001           1              SEQ
0010           2              PRG
0011           3              USR
0100           4              REL

Values 5-15 are illegal, but if used will produce very strange results.
The 1541 is inconsistent in how it treats these bits.  Some routines
use all 4 bits, others ignore bit 3, resulting in values from 0-7.

Files, on a standard 1541, are stored using an interleave of 10.
Assuming a starting track/sector of 17/0, the chain would run 17/0,
17/10, 17/20, 17/8, 17/18, etc.

15.4.1 Non-Standard & Long Directories
--------------------------------------

Most Commdore floppy disk drives use a single dedicated directory track
where all filenames are stored. This limits the number of files stored
on a disk based on the number of sectors on the directory track. There
are some disk images that contain more files than would normally be
allowed. This requires extending the directory off the default
directory track by changing the last directory sector pointer to a new
track, allocating the new sectors in the BAM, and manually placing (or
moving existing) file entries there. The directory of an extended disk
can be read and the files that reside there can be loaded without
problems on a real drive. However, this is still a very dangerous
practice as writing to the extended portion of the directory will cause
directory corruption in the non-extended part. Many of the floppy
drives core ROM routines ignore the track value that the directory is
on and assume the default directory track for operations.

To explain: assume that the directory has been extended from track 18
to track 19/6 and that the directory is full except for a few slots on
19/6. When saving a new file, the drive DOS will find an empty file
slot at 19/6 offset $40 and correctly write the filename and a few
other things into this slot. When the file is done being saved the
final file information will be written to 18/6 offset $40 instead of
19/6 causing some directory corruption to the entry at 18/6. Also, the
BAM entries for the sectors occupied by the new file will not be saved
and the new file will be left as a SPLAT (*) file.

Attempts to validate the disk will result in those files residing off
the directory track to not be allocated in the BAM, and could also send
the drive into an endless loop. The default directory track is assumed
for all sector reads when validating so if the directory goes to 19/6,
then the validate code will read 18/6 instead. If 18/6 is part of the
normal directory chain then the validate routine will loop endlessly.

15.4.2 BAM layout
-----------------

The layout of the BAM area (sector 18/0) is a bit more complicated...

               (should be set to 18/1 but it doesn't matter, and don't
               trust what is there, always go to 18/1 for first
               directory entry)
$02            Disk DOS version type (see note below) $41 ("A")
$03            Unused
$04-$8F        BAM entries for each track, in groups of four bytes per
               track, starting on track 1 (see below for more details)
$90-$9F        Disk Name (padded with $A0)
$A0-$A1        Filled with $A0
$A2-$A3        Disk ID
$A4            Usually $A0
$A5-$A6        DOS type, usually "2A"
$A7-$AA        Filled with $A0
$AB            Unused ($00)
$AC-$BF        For DOLPHIN DOS track 36-40 BAM entries, otherwise unused
               ($00)
$C0-$D3        For SPEED DOS track 36-40 BAM entries, otherwise unused
               ($00)
$D4-$FF        
Unused ($00)   

Note: The BAM entries for SPEED, DOLPHIN and ProLogic DOS use the same
layout as standard BAM entries. One of the interesting things from the
BAM sector is the byte at offset $02, the DOS version byte. If it is
set to anything other than $41 or $00, then we have what is called
"soft write protection". Any attempt to write to the disk will return
the "DOS Version" error code 73 ,"CBM DOS V 2.6 1541". The 1541 is
simply telling you that it thinks the disk format version is incorrect.
This message will normally come up when you first turn on the 1541 and
read the error channel. If you write a $00 or a $41 into 1541 memory
location $00FF (for device 0), then you can circumvent this type of
write-protection, and change the DOS version back to what it should be.

The BAM entries require a bit (no pun intended) more of a breakdown.
Take the first entry at bytes $04-$07 ($12 $FF $F9 $17).  The first
byte ($12) is the number of free sectors on that track.  Since we are
looking at the track 1 entry, this means it has 18 (decimal) free
sectors. The next three bytes represent the bitmap of which sectors are
used/free. Since it is 3 bytes (8 bits/byte) we have 24 bits of
storage. Remember that at most, each track only has 21 sectors, so
there are a few unused bits.

Bytes          Data                          Description
$04-$07        $12 $FF $F9 $17               Track 1 BAM
$08-$0B        $15 $FF $FF $FF               Track 2 BAM
$0C-$0F        $15 $FF $FF $1F               Track 3 BAM
...            ...                           ...
$8C-$8F        $11 $FF $FF $01               Track 35 BAM

These entries must be viewed in binary to make any sense. We will use
the first entry (track 1) at bytes 04-07:

 FF=11111111, F9=11111001, 17=00010111

In order to make any sense from the binary notation, flip the bits
around.

            111111 11112222
 01234567 89012345 67890123
 --------------------------
 11111111 10011111 11101000
 ^                     ^
 sector 0           sector 20

Since we are on the first track, we have 21 sectors, and only use up to
the bit 20 position. If a bit is on (1), the sector is free. Therefore,
track 1 has sectors 9, 10 and 19 used, all the rest are free. Any
leftover bits that refer to sectors that don't exist, like bits 21-23
in the above example, are set to allocated.

Each filetype has its own unique properties, but most follow one simple
structure. The first file sector is pointed to by the directory and
follows a t/s chain, until the track value reaches $00. When this
happens, the value in the sector link location indicates how much of
the sector is used. For example, the following chain indicates a file 6
sectors long, and ends when we encounter the $00/$34 chain. At this
point the last sector occupies from bytes $02-$34.

1            2            3            4            5            6

(11/00)      (11/0A)      (11/14)      (11/01)      (11/0B)      (0/34)

15.4.3 Variations on the D64 layout
-----------------------------------

These are some variations of the D64 layout:

1. Standard 35 track layout but with 683 error bytes added on to the
end of the file. Each byte of the error info corresponds to a single
sector stored in the D64, indicating if the sector on the original disk
contained an error. The first byte is for track 1/0, and the last byte
is for track 35/16.

2. A 40 track layout, following the same layout as a 35 track disk, but
with 5 extra tracks. These contain 17 sectors each, like tracks 31-35.
Some of the PC utilities do allow you to create and work with these
files. This can also have error bytes attached like variant #1.

3. The Commodore 128 allowed for "auto-boot" disks. With this, t/s 1/0
holds a specific byte sequence which the computer recognizes as boot
code.

Below is a small chart detailing the standard file sizes of D64 images,
35 or 40 tracks, with or without error bytes.

The following table (provided by Wolfgang Moser) outlines the
differences between the standard 1541 DOS and the various "speeder"
DOS's that exist. The 'header 7/8' category is the 'fill bytes' as the
end of the sector header of a real 1541 disk.

*Note: There are also clones of SpeedDOS that exist, such as RoloDOS
and DigiDOS. Both are just a change of the DOS startup string.

The location of the extra BAM information in sector 18/0, for 40 track
images, will be different depending on what standard the disks have
been formatted with. SPEED DOS stores them from $C0 to $D3, DOLPHIN DOS
stores them from $AC to $BF and PrologicDOS stored them right after the
existing BAM entries from $90-A3. PrologicDOS also moves the disk label
and ID forward from the standard location of $90 to $A4. 64COPY and
Star Commander let you select from several different types of extended
disk formats you want to create/work with.

All three of the speeder DOS's mentioned above don't alter the standard
sector interleave of 10 for files and 3 for directories. The reason is
that they use a memory cache installed in the drive which reads the
entire track in one pass. This alleviates the need for custom
interleave values.  They do seem to alter the algorithm that finds the
next available free sector so that the interleave value can deviate
from 10 under certain circumstances, but I don't know why they would
bother.

extra BAM info from $C0-D3.

15.4.4 Error codes
------------------

Here is the meaning of the error bytes added onto the end of any
extended D64. The CODE is the same as that generated by the 1541 drive
controller... it reports these numbers, not the error code we usually
see when an error occurs.

Some of what comes below is taken from Immers/Neufeld book "Inside
Commodore DOS". Note the descriptions are not completely accurate as to
what the drive DOS is actually doing to seek/read/decode/write sectors,
but serve as simple examples only. The "type" field is where the error
usually occurs, whether it's searching for any SYNC mark, any header
ID, any valid header, or reading a sector.

These first errors are "seek" errors, where the disk controller is
simply reading headers and looking at descriptor bytes, checksums,
format ID's and reporting what errors it sees. These errors do *not*
necessarily apply to the exact sector being looked for. This fact makes
duplication of these errors very unreliable.

Code    : $03 Error   : 21 Type    : Seek Message : No SYNC sequence
found.

Each sector data block and header block are preceeded by SYNC marks. If
*no* sync sequence is found within 20 milliseconds (only ~1/10 of a
disk rotation!) then this error is generated. This error used to mean
the entire track is bad, but it does not have to be the case. Only a
small area of the track needs to be without a SYNC mark and this error
will be generated.

Converting this error to a D64 is very problematic because it depends
on where the physical head is on the disk when a read attempt is made.
If it is on valid header/sectors then it won't occur. If it happens over
an area without SYNC marks, it will happen.

Code    : $02 Error   : 20 Type    : Seek Message : Header descriptor
byte not found (HEX $08, GCR $52)

Each sector is preceeded by an 8-byte GCR header block, which starts
with the value $52 (GCR). If this value is not found after 90 attempts,
this error is generated.

Basically, what a track has is SYNC marks, and possibly valid data
blocks, but no valid header descriptors.

Code    : $09 Error   : 27 Type    : Seek Message : Checksum error in
header block

The header block contains a checksum value, calculated by XOR'ing the
TRACK, SECTOR, ID1 and ID2 values. If this checksum is wrong, this
error is generated.

Code    : $0B Error   : 29 Type    : Seek Message : Disk sector ID
mismatch

The ID's from the header block of the currently read sector are
compared against the ones from the low-level header of 18/0. If there
is a mismatch, this error is generated.

Code    : $02 Error   : 20 Type    : Seek Message : Header block not
found

This error can be reported again when searching for the correct header
block. An image of the header is built and searched for, but not found
after 90 read attempts. Note the difference from the first occurance.
The first one only searches for a valid ID, not the whole header.

Note that error 20 occurs twice during this phase. The first time is
when a header ID is being searched for, the second is when the proper
header pattern for the sector being searched for is not found.

From this point on, all the errors apply to the specific sector you are
looking for. If a read passed all the previous checks, then we are at
the sector being searched for.

Note that the entire sector is read before these errors are detected.
Therefore the data, checksum and off bytes are available.

Code    : $04 Error   : 22 Type    : Read Message : Data descriptor
byte not found (HEX $07, GCR $55)

Each sector data block is preceeded by the value $07, the "data block"
descriptor. If this value is not there, this error is generated. Each
encoded sector has actually 260 bytes. First is the descriptor byte,
then follows the 256 bytes of data, a checksum, and two "off" bytes.

Code    : $05 Error   : 23 Type    : Read Message : Checksum error in
data block

The checksum of the data read of the disk is calculated, and compared
against the one stored at the end of the sector. If there's a
discrepancy, this error is generated.

Code    : $0F Error   : 74 Type    : Read Message : Drive Not Ready (no
disk in drive or no device 1)

These errors only apply when writing to a disk. I don't see the
usefulness of having these as they cannot be present when only
*reading* a disk.

Code    : $06 Error   : 24 Type    : Write Message : Write verify (on
format)

Code    : $07 Error   : 25 Type    : Write Message : Write verify error

Once the GCR-encoded sector is written out, the drive waits for the
sector to come around again and verifies the whole 325-byte GCR block.
Any errors encountered will generate this error.

Code    : $08 Error   : 26 Type    : Write Message : Write protect on

Self explanatory. Remove the write-protect tab, and try again.

Code    : $0A Error   : 28 Type    : Write Message : Write error

In actual fact, this error never occurs, but it is included for
completeness.

This is not an error at all, but it gets reported when the read of a
sector is ok.

Code    : $01 Error   : 00 Type    : N/A Message : No error.

Self explanatory. No errors were detected in the reading and decoding
of the sector.

The advantage with using the 35 track D64 format, regardless of error
bytes, is that it can be converted directly back to a 1541 disk by
either using the proper cable and software on the PC, or send it down
to the C64 and writing it back to a 1541. It is the best documented
format since it is also native to the C64, with many books explaining
the disk layout and the internals of the 1541.

15.5 The X64 disk image format
==============================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

This file type, created by Teemu Rantanen, is used on the X64 emulator
(a UNIX-based emulator) which has been superceeded by VICE. Both VICE
and X64 support the X64 file standard, with VICE also supporting the
regular D64 and T64 files.

X64 is not a specific type of file, but rather encompasses *all* known
C64 disk types (hard disk, floppies, etc). An X64 is created by
prepending a 64-byte header to an existing image (1541, 1571, etc) and
setting specific bytes which describe what type of image follows. This
header has undergone some revision, and this description is based on
the 1.02 version, which was the last known at the time of writing.

The most common X64 file you will see is the D64 variety, typically
174912 bytes long (174848 for the D64 and 64 bytes for the header,
assuming no error bytes are appended). The header layout (as used in
64COPY) is as follows:

      00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
      -----------------------------------------------

               disk)
$08            Number of disk sides in image. This value must be $00 for
               all 1541 and 1581 formats. $00=No second side $01=Second

$3F            Always set to $00
$40-           Standard C64 file begins here.

The device types are:

Value          Drive type
$00            1540 See note below...
$01            1541 (Default)
$02            1542
$03            1551
$04            1570
$05            1571
$06            1572
$08            1581
$10            2031 or 4031
$11            2040 or 3040
$12            2041
$18            4040
$20            8050
$21            8060
$22            8061
$30            SFD-1001
$31            8250
$32            8280

The first four bytes used for the device type at position $06 ($00 to
$03) are functionally the same, and are compatible with older version
of X64 files. Some old X64 files might have $00 for the device type
(instead of $01), but it makes no real difference.

As most instances of X64 files will be strictly 1541 images, bytes
$08-$3F are set to zero, and some versions of the X64 emulator don't
use bytes $08-$3F.

15.6 The D71 disk image format
==============================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

Similar to the D64 (1541), the 1571 drive can operate in either
single-sided (1541 compatible) mode or double-sided (1571) mode. In
this section I will be dealing with the double-sided mode only. For the
breakdown of the single-sided mode, see the D64 section.

The D71 has 70 tracks, double that of the 1541, with a DOS file size of
349696 bytes. If the error byte block (1366 bytes) is attached, this
makes the file size 351062 bytes. The track range and offsets into the
D71 files are as follows:

Track                                Sec/trk            # Sectors

The directory structure is the same as a D64/1541. All the same
filetypes apply, the directory still only holds 144 files per disk and
should only exist on track 18.

The first two bytes of the sector ($12/$04 or 18/4) indicate the
location of the next track/sector of the directory. If the track value
is set to $00, then it is the last sector of the directory. It is
possible, however unlikely, that the directory may *not* be competely
on track 18 (some disks do exist like this). Just follow the chain
anyhow.

When the directory is done, the track value will be $00. The sector
link should contain a value of $FF, meaning the whole sector is
allocated, but the actual value doesn't matter. The drive will return
all the available entries anyways. This is a breakdown of a standard
directory sector and entry:

This is a breakdown of a standard directory entry:

Bytes          Description
$00-$01        Track/Sector location of next directory sector ($00/$FF
               if its the last sector)
$02            File type
$03-$04        Track/sector location of first sector of file
$05-$14        16 character filename (in PETASCII, padded with $A0)
$15-$16        Track/Sector location of first side-sector block (REL
               file only)
$17            REL file record length (REL file only, max. value 254)
$18-$1D        Unused (except with GEOS disks)
$1E-$1F        File size in sectors, low/high byte order ($1E+$1F*256).
               The approx. filesize in bytes is <= #sectors * 254

The file type field is used as follows:

Bits           Description
0-3            The actual file type
4              Unused
5              Used only during SAVE-@ replacement
6              Locked flag (Set produces ">" locked files)
7              Closed flag (Not set produces "*", or "splat" files)

The actual file type can be one of the following:

Binary         Decimal        File type
0000           0              DEL
0001           1              SEQ
0010           2              PRG
0011           3              USR
0100           4              REL

Values 5-15 are illegal, but if used will produce very strange results.
The 1571 is inconsistent in how it treats these bits.  Some routines
use all 4 bits, others ignore bit 3, resulting in values from 0-7.

When the 1571 is in is native ("1571") mode, files are stored with a
sector interleave of 6, rather than 10 which the 1541 (and the 1571 in
"1541" mode) uses. The directory still uses an interleave of 3.

15.6.1 Non-Standard & Long Directories
--------------------------------------

Most Commodore floppy disk drives use a single dedicated directory
track where all filenames are stored. This limits the number of files
stored on a disk based on the number of sectors on the directory track.
There are some disk images that contain more files than would normally
be allowed. This requires extending the directory off the default
directory track by changing the last directory sector pointer to a new
track, allocating the new sectors in the BAM, and manually placing (or
moving existing) file entries there. The directory of an extended disk
can be read and the files that reside there can be loaded without
problems on a real drive. However, this is still a very dangerous
practice as writing to the extended portion of the directory will cause
directory corruption in the non- extended part. Many of the floppy
drives core ROM routines ignore the track value that the directory is
on and assume the default directory track for operations.

To explain: assume that the directory has been extended from track 18
to track 19/6 and that the directory is full except for a few slots on
19/6. When saving a new file, the drive DOS will find an empty file
slot at 19/6 offset $40 and correctly write the filename and a few
other things into this slot. When the file is done being saved the
final file information will be written to 18/6 offset $40 instead of
19/6 causing some directory corruption to the entry at 18/6. Also, the
BAM entries for the sectors occupied by the new file will not be saved
and the new file will be left as a SPLAT (*) file.

Attempts to validate the disk will result in those files residing off
the directory track to not be allocated in the BAM, and could also send
the drive into an endless loop. The default directory track is assumed
for all sector reads when validating so if the directory goes to 19/6,
then the validate code will read 18/6 instead. If 18/6 is part of the
normal directory chain then the validate routine will loop endlessly.

15.6.2 Bam layout The BAM is somewhat different as it now has to
----------------------------------------------------------------

take 35 new tracks into account. In order to do this, most of the extra
BAM information is stored on track 53/0, and the remaining sectors on
track 53 are marked in the BAM as allocated. This does mean that except
for one allocated sector on track 53, the rest of the track is unused
and wasted. (Track 53 is the equivalent to track 18, but on the flip
side of the disk). Here is a dump of the first BAM sector...

                                     (1 byte/track).

The "free sector" entries for tracks 36-70 are likely included here in
the first BAM sector due to some memory restrictions in the 1571 drive.
There is only enough memory available for one BAM sector, but in order
to generate the "blocks free" value at the end of a directory listing,
the drive needs to know the extra track "free sector" values. It does
make working with the BAM a little more difficult, though.

These are the values that would normally be with the 4-byte BAM entry,
but the rest of the entry is contained on 53/0.

Note: If the DOS version byte is set to anything other than $41 or $00,
then we have what is called "soft write protection". Any attempt to
write to the disk will return the "DOS Version" error code 73. The 1571
is simply telling you that it thinks the disk format version is
incorrect.

The BAM entries require some explanation. Take the first entry at bytes
$04-$07 ($12 $FF $F9 $17). The first byte ($12) is the number of free
sectors on that track. Since we are looking at the track 1 entry, this
means it has 18 (decimal) free sectors.

The next three bytes represent the bitmap of which sectors are
used/free. Since it is 3 bytes (8 bits/byte) we have 24 bits of
storage. Remember that at most, each track only has 21 sectors, so
there are a few unused bits. These entries must be viewed in binary to
make any sense. We will use the first entry (track 1) at bytes 04-07:

 FF=11111111, F9=11111001, 17=00010111

In order to make any sense from the binary notation, flip the bits
around.

            111111 11112222

Since we are on the first track, we have 21 sectors, and only use up to
the bit 20 position. If a bit is on (1), the sector is free. Therefore,
track 1 has sectors 9,10 and 19 used, all the rest are free.

In order to complete the BAM, we must check 53/0.

Each track from 36-70 has 3 byte entries, starting at address $00.

Byte: $00-$02: $FF $FF $1F - BAM map for track 36
      $03-$05: $FF $FF $1F - BAM map for track 37
      ...
      $33-$35: $00 $00 $00 - BAM map for track 53
      ...
      $66-$68: $FF $FF $01 - BAM map for track 70
      $69-$FF:             - Not used

You can break down the entries for tracks 36-70 the same way as track
1, just combine the free sector bytes from 18/0 and the BAM usage from
53 to get the full 4-byte entry.

Just like a D64, you can attach error bytes to the file, for sector
error information. This block is 1366 bytes long, 1 byte for each of
the 1366 sectors in the image. With the error bytes, the file size is
351062 bytes.

15.7 The D81 disk image format
==============================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

Like D64 and D71, this is a byte for byte copy of a physical 1581 disk.
It consists of 80 tracks, 40 sectors each (0 to 39) for a size of
819200 bytes, or 3200 sectors. If the error byte block is attached,
this makes the file size 822400 bytes.

There are three sectors on the directory track used for disk internals
(header and BAM), leaving 37 sectors for filename entries, thus
allowing for 296 files (37 * 8) to be stored at the root level of the
disk.

The actual physical layout on the disk is quite different from what the
user sees, but this is unimportant to the scope of this section.  One
important difference from the D64 and D71 is all the sector interleaves
are now 1 for both files and directory storage (rather than 3 for
directory and 10 for file on a D64/D71). This is due to the built-in
buffering in the 1581. When reading a sector, the whole track will be
buffered in memory, and any sectors being modified will be done in
memory. Once it has to be written, the whole track will be written out
in one step.

The track range and offsets into the D81 files are as follows:

Track              #Sect              #SectorsIn         D81 Offset

The header sector is stored at 40/0, and contains the disk name, ID and
DOS version bytes, but the BAM is no longer contained here (like the
D64).

based on the D64 layout, and might not prove to be true)

Bytes          Description
$AB-$AC        Border sector (GEOS only, else set to $00)
$AD-$BC        GEOS ID string ("geos FORMAT V1.x" GEOS only, else $00)
$BD-$FF        Unused (usually $00)

Note: If the DOS version byte is changed to anything other than a $44
(or $00), then we have what is called "soft write protection". Any
attempt to write to the disk will return the "DOS Version" error code
73. The drive is simply telling you that it thinks the disk format
version is incompatible.

The directory track should be contained totally on track 40.  Sectors
3-39 contain the entries and sector 1 and 2 contain the BAM (Block
Availability Map). Sector 0 holds the disk name and ID. The first
directory sector is always 40/3, even though the t/s pointer at 40/0
(first two bytes) might point somewhere else. It goes linearly up the
sector count, 3-4-5-6-etc. Each sector holds up to eight entries.

The first two bytes of the sector ($28/$04) indicate the location of
the next track/sector of the directory (40/4). If the track is set to
$00, then it is the last sector of the directory. It is possible,
however unlikely, that the directory may *not* be competely on track
40. Just follow the chain anyhow.

When the directory is done (track=$00), the sector should contain an
$FF, meaning the whole sector is allocated. Theactual value doesn't
matter as all the entries will be returned anyways. Each directory
sector has the following layout:

This is a breakdown of a standard directory entry:

$00-$01        Track/Sector location of next directory sector
$02            File type
$03-$04        Track/sector location of first sector of file or partition
$05-$14        16 character filename (in PETASCII, padded with $A0)
$15-$16        Track/Sector location of first SUPER SIDE SECTOR block
               (REL file only)
$17            REL file record length (REL file only)
$18-$1B        Unused (except with GEOS disks)
$1C-$1D        (Used during an SAVE or OPEN, holds the new t/s link)
$1E-$1F        File or partition size in sectors, low/high byte order
               ($1E+$1F*256). The approx. file size in bytes is <=
               #sectors * 254

The file type field is used as follows:

Bits           Description
0-3            The actual file type
4              Unused
5              Used only during SAVE-@ replacement
6              Locked flag (Set produces ">" locked files)
7              Closed flag (Not set produces "*", or "splat" files)

The actual file type can be one of the following:

Binary         Decimal        File type
0000           0              DEL
0001           1              SEQ
0010           2              PRG
0011           3              USR
0100           4              REL
0101           5              CBM (partition or sub-directory)

Values 6-15 are illegal, but if used will produce very strange results.

15.7.1 Non-Standard & Long Directories
--------------------------------------

Most Commdore floppy disk drives use a single dedicated directory track
where all filenames are stored. This limits the number of files stored
on a disk based on the number of sectors on the directory track. There
are some disk images that contain more files than would normally be
allowed. This requires extending the directory off the default
directory track by changing the last directory sector pointer to a new
track, allocating the new sectors in the BAM, and manually placing (or
moving existing) file entries there. The directory of an extended disk
can be read and the files that reside there can be loaded without
problems on a real drive. However, this is still a very dangerous
practice as writing to the extended portion of the directory will cause
directory corruption in the non-extended part. Many of the floppy
drives core ROM routines ignore the track value that the directory is
on and assume the default directory track for operations.

15.7.2 BAM layout
-----------------

The BAM is located on 40/1 (for side 0, tracks 1-40) and 40/2 (for side
1, tracks 41-80). Each entry takes up six bytes, one for the "free
sector" count and five for the allocation bitmap.

$10-$15: BAM entry for track 1 (track 41, side 1)
$16-$1B: BAM entry for track 2 (track 42, side 1)
         ...

         ...
$82-$87: BAM entry for track 20 (track 60, side 1)
         ...
$BE-$C3: BAM entry for track 30 (track 70, side 1)
         ...
$FA-$FF: BAM entry for track 40 (track 80, side 1)

The BAM entries require some explanation, so lets look at the track 40
entry at bytes $FA-FF ($24 $F0 $FF $2D $FF $FE). The first byte ($24,
or 36 decimal) is the number of free sectors on that track. The next
five bytes represent the bitmap of which sectors are used/free. Since
it is five bytes (8 bits/byte) we have 40 bits of storage. Since this
format has 40 sectors/track, the whole five bytes are used.

 F0: .. .. .. .. .. .. .. .. .. .. 24 F0 FF 2D FF FE

The last five bytes of any BAM entry must be viewed in binary to make
any sense. We will once again use track 40 as our reference:

 F0=11110000, FF=11111111, 2D=00101101, FF=11111111, FE=11111110

In order to make any sense from the binary notation, flip the bits
around.

                   111111 11112222 22222233 33333333
 Sector 01234567 89012345 67890123 45678901 23456789
        -------------------------- -------- --------
        00001111 11111111 10110100 11111111 01111111

Note that if a bit is on (1), the sector is free. Therefore, track 40
has sectors 0-3, 17, 20, 22, 23 and 32 used, all the rest are free.

The second BAM (for side 1) contains the entries for tracks 41-80.

It is laid out exactly as the side 0 BAM except for one difference. The
track/sector reference for the next sector should be set to $00/$FF,
indicating there is no next sector.

15.7.3 REL files The REL filetype requires some extra explaining.
-----------------------------------------------------------------

It was designed to make access to data *anywhere* on the disk very
fast. Take a look at this directory entry...

 00: 00 FF 84 27 00 41 44 44 49 54 49 4F 4E 41 4C 20
 10: 49 4E 46 4F A0 27 02 FE 00 00 00 00 00 00 D2 0B

The third byte ($84) indicates this entry is a REL file and that the
three normally empty entries at offset $15, $16 and $17 are now used as
they are explained above. It's the track/sector chain that this entry
points to, called the SUPER SIDE SECTOR, which is of interest here (in
this case, 39/2).  The SUPER SIDE SECTOR is very different from the D64
format. If you check the D64 entry for a REL file and do the
calculations, you will find that the maximum file size of the REL file
is 720 data sectors. With the new SUPER SIDE SECTOR, you can now have
126 groups of these SIDE SECTORS chains, allowing for file sizes up to
(theoretically) 90720 sectors, or about 22.15 Megabytes.

Here is a dump of the beginning of the SUPER SIDE SECTOR...

 00: 27 01 FE 27 01 15 09 03 0F 38 16 4A 1C 00 00 00
 10: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
 20: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Bytes:
$00-$01: Track/sector of first side sector in group 0
    $02: Always $FE
$03-$04: Track/sector of first side sector in group 0 (again)
         ...
$FD-$FE: Track/sector of first side sector in group 125
    $FF: Unused (likely $00)

The side sector layout is the same as the D64/1571.

    $01: Sector location of next side-sector
    $02: Side-sector block number (first sector is $00, the next is
         $01, then $02, etc)
    $03: REL file RECORD size (from directory entry)
$04-$0F: Track/sector locations of the six other side-sectors. Note
         the first entry is this very sector we have listed here.
         The next is the next t/s listed at the beginning of the
         sector. All of this information must be correct. If one of
         these chains is $00/$00, then we have no more side sectors.
         Also, all of these (up to six) side sectors must have the
         same values in this range.
$10-$FF: T/S chains of *each* sector of the data portion. When we
         get a $00/$00, we are at the end of the file.

15.7.4 1581 Partitions and Sub-directories
------------------------------------------

At the beginning of this section it was stated that the 1581 can hold
296 entries "at the root level". The 1581 also has the ability to
partition areas of the disk. Under the right conditions these can
become sub-directories, acting as a small diskette, complete with its
own directory and BAM. When you are inside of a sub-directory, no other
files except those in that directory are visible, or can be affected.

To the 1581, this file will show up as a "CBM" filetype in a directory.
All this does is tell the disk that a file, starting at X/Y
track/sector and Z sectors large exists. Doing a validate will not harm
these files as they have a directory entry, and are fully allocated in
the BAM.

There are two main uses for partitions. One is to simply allocate a
section of the disk to be used for direct-access reads/writes, and lock
it away from being overwritten after a VALIDATE. The second is as a
sub-directory, basically a small "disk within a disk".

In order to use a partition as a sub-directory, it must adhere to the
following four rules:

 1. If must start on sector 0
 2. It's size must be in multiples of 40 sectors
 3. It must be a minimum of 120 sectors long (3 tracks)
 4. If must not start on or cross track 40, which limits the
    biggest directory to 1600 sectors (tracks 1-39).

This is a dump of a sub-directory entry:

 00: 00 FF 85 29 00 50 41 52 54 49 54 49 4F 4E 20 31
 10: A0 A0 A0 A0 A0 00 00 00 00 00 00 00 00 00 40 06

It is a partition starting on track 41/0, extends for 1600 sectors, and
has been formatted as a sub-directory. Note that when a partition is
created, the area being allocated is not touched in any way. If you
want it set up as a sub-directory, you must issue the FORMAT command to
the 1581 to create the central directory and BAM. Also note that from
the directory entry you can't tell whether it is a sub-directory or
not, just that it fits the sub-directory parameters.

The BAM track for the sub-directory exists on the first track of the
partition, and has the same layout as the disk BAM on track 40. The
biggest difference is the "disk name" is what what given when the
partition was formatted rather than what the actual disk name is. Also,
except for the free sectors in the partition area, all other sectors in
the BAM will be allocated.

If the partition size doesn't match the above rules for a
sub-directory, it will simply exist as a "protected" area of the disk,
and can't be used as a sub-directory. Either way, it still shows up as
a "CBM" type in a directory listing. Below is a dump of a 10-sector
partition starting on track 5/1, which does not qualify as a
sub-directory...

 00: 00 00 85 05 01 53 4D 41 4C 4C 50 41 52 54 20 32
 10: A0 A0 A0 A0 A0 00 00 00 00 00 00 00 00 00 0A 00

The master BAM shows the entry for this partition on track 5...

 00: 28 02 44 BB 43 44 C0 00 00 00 00 00 00 00 00 00
 10: 23 C1 FF FF FF FF 28 FF FF FF FF FF 28 FF FF FF
 20: FF FF 28 FF FF FF FF FF 1E 01 F8 FF FF FF 28 FF
                             ^^^^^^^^^^^^^^^^^

The breakdown of the BAM shows the allocation for this track, with
sectors 1-10 allocated, as it should be.

 10000000 00011111 11111111 11111111 11111111
 ^          ^          ^         ^          ^
 0          10         20        30         39

Partitions and sub-directories share one very important trait.  When
created, the sub-directory entry simply has the starting track/sector
and the size of the partition in sectors.  Partitions are created
linearly, meaning if one starts on 30/1 and is of size 15 sectors, then
the sector range from 1 through 15 on track 30 will be allocated. If a
partition size crosses a track boundary, the allocation will continue
on the next track starting on sector 0, and going up.

The section allocated will *not* have a track/sector chain like a file
would, but rather is dependant on the directory entry to keep it from
being overwritten. You can store whatever you want to in the allocated
area.

15.7.5 AUTO-BOOT LOADER
-----------------------

If byte $07 in the BAM is set, then when the drive is reset (and other
circumstances) it will look for a USR file called "COPYRIGHT CBM 86".
This file will then be loaded into the drive RAM and executed.

The format for this auto-loader file is fairly basic. It starts with a
two-byte load address, a size byte, program data, and a checksum at the
end.

Bytes:
       $00-$01: Load address, low/high format
           $02: Size of program (SZ) (smaller than 256 bytes)
$03-($03+SZ-1): Program data
        $03+SZ: Checksum byte

==============================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

This is a sector-for-sector copy of an 8050 floppy disk. The file size
for an 8050 image is 533248 bytes. It is comprised of 256-byte sectors
arranged across 77 tracks, with a varying number of sectors per track
for a total of 2083 sectors. Track counting starts at 1 (not 0) and
sector counting starts at 0 (not 1), therefore a track with 29 sectors
will go from 0 to 28.

The original media (a 5.25" disk) has the tracks laid out in circles,
with track 1 on the very outside of the disk (closest to the sides) to
track 77 being on the inside of the disk (closest to the inner hub
ring). Commodore, in their infinite wisdom, varied the number of
sectors per track and data densities across the disk to optimize
available storage, resulting in the chart below. It shows the
sectors/track for a D80. Since the outside diameter of a circle is the
largest (versus closer to the center), the outside tracks have the
largest amount of storage.

The BAM (Block Availability Map) is on track 38. The D80 is only 77
tracks and so the BAM is contained on 38/0 and 38/3. The BAM interleave
is 3.

The directory is on track 39, with 39/0 contains the header (DOS type,
disk name, disk ID's) and sectors 1-28 contain the directory entries.
Both files and the directory use an interleave of 1. Since the
directory is only 28 sectors large (29 less one for the header), and
each sector can contain only 8 entries (32 bytes per entry), the
maximum number of directory entries is 28 * 8 = 224. The first
directory sector is always 39/1. It then follows a chain structure
using a sector interleave of 1 making the links go 39/1, 39/2, 39/3 etc.

When reading a disk, you start with 39/0 (disk label/ID) which points
to 38/0 (BAM0), 38/3 (BAM1), and finally to 39/1 (first dir entry
sector). When writing a file to a blank disk, it will start at 38/1
because 38/0 is already allocated.

Below is a dump of the header sector 39/0:

The first two bytes of the directory sector ($27/$02) indicate the
location of the next track/sector of the directory (39/2).  If the
track is set to $00, then it is the last sector of the directory.

When the directory is done, the track value will be $00. The sector
link should contain a value of $FF, meaning the whole sector is
allocated, but the actual value doesn't matter. The drive will return
all the available entries anyways. This is a breakdown of a standard
directory sector:

Bytes          Description
$00-$1F        First directory entry
$20-$3F        Second dir entry
$40-$5F        Third dir entry
$60-$7F        Fourth dir entry
$80-$9F        Fifth dir entry
$A0-$BF        Sixth dir entry
$C0-$DF        Seventh dir entry
$E0-$FF        Eighth dir entry

This is a breakdown of a standard directory entry:

Bytes          Description
$00-$01        Track/Sector location of next directory sector ($00 $00
               if not the first entry in the sector)
$02            File type
$03-$04        Track/sector location of first sector of file
$05-$14        16 character filename (in PETASCII, padded with $A0)
$15-$16        Track/Sector location of first side-sector block (REL
               file only)
$17            REL file record length (REL file only, max. value 254)
$18-$1D        Unused
$1E-$1F        File size in sectors, low/high byte order ($1E+$1F*256).
               The approx. filesize in bytes is <= #sectors * 254

The file type field is used as follows:

Bits           Description
0-3            The actual file type
4              Unused
5              Used only during SAVE-@ replacement
6              Locked flag (Set produces ">" locked files)
7              Closed flag (Not set produces "*", or "splat" files)

The actual file type can be one of the following:

Binary         Decimal        File type
0000           0              DEL
0001           1              SEQ
0010           2              PRG
0011           3              USR
0100           4              REL

Values 5-15 are illegal, but if used will produce very strange results.

15.8.1 Non-Standard & Long Directories
--------------------------------------

Most Commdore floppy disk drives use a single dedicated directory track
where all filenames are stored. This limits the number of files stored
on a disk based on the number of sectors on the directory track. There
are some disk images that contain more files than would normally be
allowed. This requires extending the directory off the default
directory track by changing the last directory sector pointer to a new
track, allocating the new sectors in the BAM, and manually placing (or
moving existing) file entries there. The directory of an extended disk
can be read and the files that reside there can be loaded without
problems on a real drive. However, this is still a very dangerous
practice as writing to the extended portion of the directory will cause
directory corruption in the non-extended part. Many of the floppy
drives core ROM routines ignore the track value that the directory is
on and assume the default directory track for operations.

15.8.2 BAM layout
-----------------

The BAM only occupies up to four sectors on track 38, so the rest of
the track is empty and is available for file storage.  Below is a dump
of the first BAM block, 38/0. A D80 will only contain two BAM sectors,
38/0 and 38/3. Each entry takes 5 bytes, 1 for the free count on that
track, and 4 for the BAM bits.

                       free" for this track, the remaining 4 show the
                       BAM for the track.

...                    ...
$FB-$FF                BAM for track 50

Being bit-based, the BAM entries need some explanation. The first track
entry in the above BAM sector is at offset 06, "1D FF FF FF 1F". The
first number is how many blocks are free on this track ($1D=29) and the
remainder is the bit representation of the usage map for the track.
These entries must be viewed in binary to make any sense. First convert
the values to binary:

 FF=11111111, FF=11111111, FF=11111111, 1F=00011111

In order to make any sense from the binary notation, flip the bits
around.

            111111 11112222 222222
 01234567 89012345 67890123 456789...
 -------------------------- ---------
 11111111 11111111 11111111 11111000
 ^                              ^
 sector 0                   sector 28

Since we are on the first track, we have 29 sectors, and only use up to
the bit 28 position. If a bit is on (1), the sector is free. Therefore,
track 1 is clean, all sectors are free.  Any leftover bits that refer
to sectors that don't exist, like bits 29-31 in the above example, are
set to allocated.

Second BAM block 38/3.

15.9 The D82 disk image format
==============================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

This is a sector-for-sector copy of an 8250 floppy disk. The file size
for an 8250 image is 1066496 bytes. It is comprised of 256-byte sectors
arranged across 154 tracks, with a varying number of sectors per track
for a total of 4166 sectors. Track counting starts at 1 (not 0) and
sector counting starts at 0 (not 1), therefore a track with 29 sectors
will go from 0 to 28.

The original media (a 5.25" disk) has the tracks laid out in circles,
with track 1 on the very outside of the disk (closest to the sides) to
track 77 being on the inside of the disk (closest to the inner hub
ring). Commodore, in their infinite wisdom, varied the number of
sectors per track and data densities across the disk to optimize
available storage, resulting in the chart below. It shows the
sectors/track for a D82. Since the outside diameter of a circle is the
largest (versus closer to the center), the outside tracks have the
largest amount of storage.

Track Range              Sectors/track            # Sectors

The BAM (Block Availability Map) is on track 38. The D82 is 154 tracks
and so the BAM is contained on 38/0, 38/3, 38/6 and 38/9.  The BAM
interleave is 3.

The directory is on track 39, with 39/0 contains the header (DOS type,
disk name, disk ID's) and sectors 1-28 contain the directory entries.
Both files and the directory use an interleave of 1. Since the
directory is only 28 sectors large (29 less one for the header), and
each sector can contain only 8 entries (32 bytes per entry), the
maximum number of directory entries is 28 * 8 = 224. The first
directory sector is always 39/1. It then follows a chain structure
using a sector interleave of 1 making the links go 39/1, 39/2, 39/3 etc.

When reading a disk, you start with 39/0 (disk label/ID) which points
to 38/0 (BAM0), 38/3 (BAM1), 38/6 (BAM2), 38/9 (BAM3, and finally to
39/1 (first dir entry sector). When writing a file to a blank disk, it
will start at 38/1 because 38/0 is already allocated.

Below is a dump of the header sector 39/0:

The first two bytes of the directory sector ($27/$02) indicate the
location of the next track/sector of the directory (39/2).  If the
track is set to $00, then it is the last sector of the directory.

When the directory is done, the track value will be $00. The sector
link should contain a value of $FF, meaning the whole sector is
allocated, but the actual value doesn't matter. The drive will return
all the available entries anyways. This is a breakdown of a standard
directory sector:

Bytes          Description
$00-$1F        First directory entry
$20-$3F        Second dir entry
$40-$5F        Third dir entry
$60-$7F        Fourth dir entry
$80-$9F        Fifth dir entry
$A0-$BF        Sixth dir entry
$C0-$DF        Seventh dir entry
$E0-$FF        Eighth dir entry

This is a breakdown of a standard directory entry:

Bytes          Description
$00-$01        Track/Sector location of next directory sector ($00 $00
               if not the first entry in the sector)
$02            File type
$03-$04        Track/sector location of first sector of file
$05-$14        16 character filename (in PETASCII, padded with $A0)
$15-$16        Track/Sector location of first side-sector block (REL
               file only)
$17            REL file record length (REL file only, max. value 254)
$18-$1D        Unused
$1E-$1F        File size in sectors, low/high byte order ($1E+$1F*256).
               The approx. filesize in bytes is <= #sectors * 254

The file type field is used as follows:

Bits           Description
0-3            The actual file type
4              Unused
5              Used only during SAVE-@ replacement
6              Locked flag (Set produces ">" locked files)
7              Closed flag (Not set produces "*", or "splat" files)

The actual file type can be one of the following:

Binary         Decimal        File type
0000           0              DEL
0001           1              SEQ
0010           2              PRG
0011           3              USR
0100           4              REL

Values 5-15 are illegal, but if used will produce very strange results.

15.9.1 Non-Standard & Long Directories
--------------------------------------

Most Commdore floppy disk drives use a single dedicated directory track
where all filenames are stored. This limits the number of files stored
on a disk based on the number of sectors on the directory track. There
are some disk images that contain more files than would normally be
allowed. This requires extending the directory off the default
directory track by changing the last directory sector pointer to a new
track, allocating the new sectors in the BAM, and manually placing (or
moving existing) file entries there. The directory of an extended disk
can be read and the files that reside there can be loaded without
problems on a real drive. However, this is still a very dangerous
practice as writing to the extended portion of the directory will cause
directory corruption in the non-extended part. Many of the floppy
drives core ROM routines ignore the track value that the directory is
on and assume the default directory track for operations.

15.9.2 BAM layout
-----------------

The BAM only occupies up to four sectors on track 38, so the rest of
the track is empty and is available for file storage.  Below is a dump
of the first BAM block, 38/0. A D82 will contain four BAM sectors,
38/0, 38/3, 38/6 and 38/9. Each entry takes 5 bytes, 1 for the free
count on that track, and 4 for the BAM bits.

$06-$0A                BAM for track 1. The first byte shows the "blocks
                       free" for this track, the remaining 4 show the
                       BAM for the track.

...                    ...
$FB-$FF                BAM for track 50

Being bit-based, the BAM entries need some explanation. The first track
entry in the above BAM sector is at offset 06, "1D FF FF FF 1F". The
first number is how many blocks are free on this track ($1D=29) and the
remainder is the bit representation of the usage map for the track.
These entries must be viewed in binary to make any sense. First convert
the values to binary:

 FF=11111111, FF=11111111, FF=11111111, 1F=00011111

In order to make any sense from the binary notation, flip the bits
around.

            111111 11112222 222222
 01234567 89012345 67890123 456789...
 -------------------------- ---------
 11111111 11111111 11111111 11111000
 ^                              ^
 sector 0                  sector 28

Since we are on the first track, we have 29 sectors, and only use up to
the bit 28 position. If a bit is on (1), the sector is free. Therefore,
track 1 is clean, all sectors are free. Any leftover bits that refer to
sectors that don't exist, like bits 29-31 in the above example, are set
to allocated.

15.10 The P00 image format
==========================

(This section was contributed by Peter Schepers and slightly edited by
Marco van den Heuvel.)

These files were created for use in the PC64 emulator, written by
Wolfgang Lorenz. Each one has the same layout with the filetype being
stored in the DOS extension (i.e. Pxx is a PRG, Sxx is a SEQ, Uxx is a
USR and Rxx is a RELative file), and the header is only 26 bytes long.

This is a dump of a Pxx file (PRG)...

0010: 4F 55 4E 54 41 49 4E 00 00 00

Bytes                  Description
$00-$06                ASCII string "C64File"
$07                    Always $00
$08-$17                Filename in PETASCII, padded with $00 (not $A0,
                       like a D64)
$18                    Always $00
$19                    REL file record size ($00 if not a REL file)
$1A-??                 Program data

The 'xx' in the extension of the file is usually 00, except when we
have two DOS filenames which would be the same, but the C64 filenames
are different! If we have two C64 filenames which are the same, they
*cannot* co-exist in the same directory. If we have two files which do
convert down to be the same DOS filename, the extension is incremented
until an unused one is found (x01, x02, x03, up to x99). We can have up
to 99 different C64 files with the same corresponding DOS names as
that's all the extension will hold (from P00 to P99).

Each PC64 file only has one entry, there are no multi-file containers
allowed. This could result in a large number of these files in a
directory, even for only a few programs, as each C64 file will result
in a PC64 file entry. The best use for a PC64 file is a single-file
program, one which does not load anything else.

15.11 The CRT cartridge image format
====================================

This chapter is based on CRT.txt (rev1.14) compiled by Peter Schepers,
with additional contributions from Per Hakan Sundell, Markus Brenner,
Marco Van Den Heuvel, Groepaz.

Cartridge files were introduced in the CCS64  emulator,  written  by
Per Hakan Sundell, and use the ".CRT" file extension. This format  was
created to handle the various ROM cartridges that exist, such as Action
Replay, the Power cartridge, and the Final Cartridge.

Normal game cartridges can load  into  several  different  memory
ranges ($8000-9FFF,  $A000-BFFF  or  $E000-FFFF).  Newer   utility
and   freezer cartridges were less intrusive, hiding themselves until
called  upon,  and still others used bank-switching techniques to allow
much larger ROM's than normal. Because of these "stealthing" and
bank-switching methods, a special cartridge format  was  necessary,  to
let  the  emulator  know  where  the cartridge should reside, the
control line  states  to  enable  it  and  any special hardware
features it uses.

The following is the contents of the CHIP packet, from position $0040
on in the CRT file. Note I have re-adjusted the starting address to be
$0000, since we are now looking at a file contained in the .CRT file,
and all size references are from where it starts.

From the above chart, the following table can be built. It shows
standard cartridges, either 8K or 16K in size, and the memory ranges
they load into.

Type     Size   Game   EXRom  Low Bank  High Bank
         in K   Line   Line    (ROML)    (ROMH)
-------------------------------------------------
Normal    8k     hi     lo     $8000      ----
Normal    16k    lo     lo     $8000     $A000
Ultimax   8k     lo     hi     $E000      ----

The ROMH and ROML lines are CPU-controlled status  lines,  used  to
bank in/out RAM, ROM or I/O, depending on what is needed at the time.

Ultimax cartridges typically are situated  in  the  $E000-FFFF  (8K)
ROM address range. There are some cartridges  which  only  use  4K  of
the  8K allocation. If the cartridge is 16K in size, then it will
reside  in  both $8000-9FFF and $E000-FFFF.

This cart has 32Kb of ROM, and 8Kb of RAM. The bank switching  is  done
   by writing to the I/O-1 range as follows:

    bit  meaning
    ---  -------
    7    extra ROM bank selector (A15) (unused)
    6    1 = resets FREEZE-mode (turns back to normal mode)
    5    1 = enable RAM at ROML ($8000-$9FFF) &
             I/O-2 ($DF00-$DFFF = $9F00-$9FFF)
    4    ROM bank selector high (A14)
    3    ROM bank selector low  (A13)
    2    1 = disable cartridge (turn off $DE00)

A total of 64 kB of ROM memory  is  organized  into  four  $4000  banks
   located at $8000-$BFFF.

The banks are arranged in the following way:

    Bank 0:  BASIC, Monitor, Disk-Turbo
    Bank 1:  Notepad, BASIC (Menu Bar)
    Bank 2:  Desktop, Freezer/Print
    Bank 3:  Freezer, Compression

The cartridges uses the entire I/O-1 and I/O-2 range. Bank switching is
   done by writing the bank number plus $40 into  memory  location
$DFFF.      For instance, to select bank 2, $DFFF is set to $42.

The CRT file contains four CHIP blocks, each block with a start address
   of $8000, length $4000 and the bank number in the bank  field.  In
the     cartridge header, both EXROM ($18) and GAME  ($19)  are  set
to  1  to     enable the 16 kB ROM configuration.

The registers are arranged in the following way:

One register at $DFFF:

    bit  meaning
    ---  -------
    7      Hide this register (1 = hidden)
    6      NMI line  (0 = low = active) *1)
    5      GAME line  (0 = low = active) *2)
    4      EXROM line (0 = low = active)
    2-3    unassigned (usually set to 0)
    0-1    number of bank to show at $8000

1) if either the freezer button is pressed, or bit 6 is 0, then an  NMI

2) if the freezer button is pressed, GAME is also forced low

The rest of I/O-1/I/O-2 contain a mirror of the last  2  pages  of  the
   currently selected ROM bank (also at $dfff, contrary to what some
other     documents say)

Simons' BASIC permanently uses 16 kB ($4000) bytes of cartridge  memory
   from $8000-$BFFF. However, through some custom bank-switching logic
the     upper area ($A000-$BFFF) may be disabled so Simons' BASIC may
use it as     additional RAM. Writing a value of $01 to address
location $DE00  banks     in ROM, $00 disables ROM and enables RAM.

The CRT file contains two CHIP blocks of length $2000 each,  the  first
   block having a start address of $8000, the second block $A000.  In
the     cartridge header, EXROM ($18) is set to 0, GAME ($19) is set
to  1  to     indicate the RESET/power-up configuration of 8 kB ROM.

The FUN PLAY Cartridge uses $DE00 for  bank  selection,  and  uses  8Kb
   banks ($2000) at $8000-$9FFF. There are 16 banks of ROM memory and
are     referenced by the following values:

    $00 -> Bank 0
    $08 -> Bank 1
    $10 -> Bank 2
    $18 -> Bank 3
    $20 -> Bank 4
    $28 -> Bank 5
    $30 -> Bank 6
    $38 -> Bank 7
    $01 -> Bank 8
    $09 -> Bank 9
    $11 -> Bank 10
    $19 -> Bank 11
    $21 -> Bank 12
    $29 -> Bank 13
    $31 -> Bank 14
    $39 -> Bank 15

The bank field in the chip  headers  is  set  according  to  the  value
   written to $DE00. The following bits are  used  for  bank  decoding
in     $DE00 (0 being the LSB, 3 being the MSB).

        Bit# 76543210
             xx210xx3

After copying memory from the ROM banks, the selection  program  writes
   a value of $86 to $DE00. This seems either  to  reset  or  disable
the     cartridge ROM.

The Super Games cartridge  uses  4  16Kb  banks  ($8000-$BFFF)  of  ROM
   memory. Bank selecting is done by writing to $DF00.

$DF00 register is as follows:

    bit  meaning
    ---  -------
    0    bank bit 0
    1    bank bit 1
    2    inverted GAME line
    3    inverted EXROM line

This cart has 32Kb of ROM and 8Kb of RAM

Writing to I/O-1 will do the following:

    bit  meaning
    ---  -------
    7    extra ROM bank selector (A15) (unused)
    6    1 = resets FREEZE-mode (turns back to normal mode)
    5    1 = enable RAM at ROML ($8000-$9FFF) &
             I/O-2 ($DF00-$DFFF = $9F00-$9FFF)
    4    ROM bank selector high (A14)
    3    ROM bank selector low  (A13)
    2    1 = disable cartridge (turn off $DE00)
    1    1 = /EXROM high
    0    1 = /GAME low

If bit 5 (RAM enable) is 1, bit 0,1 (exrom/game) is ==  2  (cart  off),
   bit 2,6,7 (cart disable, freeze clear) are 0, then cart ROM (Bank
0..3)     is mapped at 8000-9FFF, and cart RAM (Bank 0) is  mapped  at
A000-BFFF     and cart RAM (Bank 0) is is enabled in the I/O-2 area
using  16Kb  game     config.

The cart RAM or ROM is available through a window in the I/O-2 range.

The Epyx FastLoad cart uses a simple capacitor to toggle the ROM on
and off:

the capacitor is discharged, and 8k game config enabled, by either
reading ROML or reading I/O-1. If none of those accesses happen the
capacitor will charge, and if it is charged (after 512 cycles) then
the ROM will get disabled.

Here is a list of the known cartridges:

    C64GS 4-in-1      (Commodore)  (512 kB)
    Last Ninja Remix  (System 3)   (512 kB)
    Myth              (System 3)   (512 kB)

ROM memory is organized in 8Kb ($2000) banks  located  at  $8000-$9FFF.
   Bank switching is done by writing to address $DE00+X, where  X  is
the     bank number (STA $DE00,X). For instance, to read from bank  3,
address     $DE03 is written to. Reading from anywhere  in  the  I/O-1
range  will     disable the cart.

The CRT file contains a string of CHIP blocks, each block with a  start
   address of $8000, length $2000 and the bank number in the  bank
field.      In the cartridge header, EXROM ($18) is set to 0, GAME
($19) is set  to     1 to enable the 8 kB ROM configuration.

After  RESET  or  POWER  ON,  16kB  of  cartridge  ROM  is  visible  at
   $8000-$BFFF. Additionally,  ROM  normally  located  at  $9E00-$9FFF
is     mirrored into I/O-1 and I/O-2 at $DE00-$DFFF.  ROM  at
$8000-$BFFF  is     disabled by writing into the I/O-2 area (typically
$DF00)  and  may  be     re-enabled by writing into  I/O-1  ($DE00).
However,  the  $DE00-$DFFF     (I/O-1/I/O-2) area itself always remains
mapped to cartridge ROM.

Here is a list of the known DINAMIC cartridges:

    Narco Police  (128 kB)
    Satan         (128 kB)

ROM memory is organized in 8Kb ($2000) banks  located  at  $8000-$9FFF.
   Bank switching is done by reading from address $DE00+X, where X is
the     bank number (LDA $DE00,X). For instance, to read from bank  3,
address     $DE03 is accessed.

The CRT file contains a string of CHIP blocks, each block with a  start
   address of $8000, length $2000 and the bank number in the  bank
field.      In the cartridge header, EXROM ($18) is set to 0, GAME
($19) is set  to     1 to enable the 8 kB ROM configuration.

The (Super) Zaxxon carts use a 4Kb ($1000) ROM at $8000-$8FFF (mirrored
   in $9000-$9FFF) along with two 8Kb ($2000) cartridge banks  located
at     $A000-$BFFF. One of the two banks is selected by doing a read
access to     either the $8000-$8FFF area (bank 0 is selected) or to
$9000-$9FFF area     (bank 1 is selected). EXROM ($18 = $00) and GAME
($19 = $00) lines  are     always pulled to GND to select the 16 kB ROM
configuration.

The CRT file includes three CHIP blocks:
    a) bank = 0, load address = $8000, size = $1000
    b) bank = 0, load address = $A000, size = $2000
    c) bank = 1, load address = $A000, size = $2000

This cartridge type is very similar to the OCEAN cart type: ROM  memory
   is  organized  in  8Kb  ($2000)  banks  located  at  $8000-$9FFF.
Bank     switching is done by writing the bank number to $DE00. Deviant
from the     Ocean type, bit 8 is cleared for selecting one of the ROM
banks. If bit     8 is set ($DE00 = $80), the GAME/EXROM lines are
disabled,  turning  on     RAM at $8000-$9FFF instead of ROM.

In the cartridge header, EXROM ($18) is set to 0, GAME ($19) is set  to
   1 to indicate the RESET/power-up configuration of 8 kB ROM.

Here is a list of the known cartridges:

    Ghosbusters        (HES Australia)   (32 kB)
    Magic Desk         (Commodore)       (32 kB)
    Badlands           (Domark)          (64 kB)
    Vindicators        (Domark)          (64 kB)
    Wonderboy          (HES Australia)   (64 kB)
    Cyberball          (Domark)         (128 kB)

This is an eprom cartridge. It has 1 2764 (8Kb) which  holds  the  base
   eprom with the base menu, and 2 27256 eproms of  which  8Kb  parts
are     banked into the $8000-9FFF area.

The bank selecting is done by writing to $DE00. The following bits  are
   used for bank decoding in $DE00 (0 being the LSB, 3 being the MSB).

         Bit# 76543210
              xx10xx32

Any bank value below 4 or above 11 switches in the base bank (bank 0).

The bit values for each eprom bank are :

    eprom bank 1 : xx00xx01
    eprom bank 2 : xx01xx01
    eprom bank 3 : xx10xx01
    eprom bank 4 : xx11xx01
    eprom bank 5 : xx00xx10
    eprom bank 6 : xx01xx10
    eprom bank 7 : xx10xx10
    eprom bank 8 : xx11xx10

Setting bit 7 high will switch off EXROM.

This is an eprom cartridge. It has 9 eprom sockets, of which the  first
   holds the base eprom with the base menu which  is  an  8Kb  eprom,
the     other eprom sockets can handle 8Kb, 16Kb or 32Kb eproms, of
which  8kb     can be banked into the $8000-9FFF area.

The bank selecting is done by  writing  to  $DFA0.  Bits  2,  1  and  0
   determine which socket is used and bits 5 and 4 are used to  select
an     8Kb piece of the eprom.

The possible values for bits 5 and 4 for the (extra) eprom banks are:

     8Kb        : 3, 2, 1, 0

    16Kb bank 0 : 2, 0
    16Kb bank 1 : 3, 1

    32Kb bank 0 : 0
    32Kb bank 1 : 1
    32Kb bank 2 : 2
    32Kb bank 3 : 3

Reading from $DFC0 switches off the EXROM.      Reading from $DFE0
switches on the EXROM.

This cart has 32Kb of ROM, bank 0 is in the cart image but is  unused.
   The first 8Kb of the cart image is unused, the second 8Kb of the
cart     image is mapped to $E000-$FFFF, the third 8Kb of  the  cart
image  is     mapped to $8000-$9FFF and the fourth 8Kb of the cart
image  is  mapped     to $A000-$BFFF. An NMI can be triggered by the
cart, if address  $0001     is written to and the cartridge is enabled.
The cart can  be  disabled     by software, by clearing bit 4 when
writing to $DF00-$DFFF.  Cart  ROM     at $E000-$FFFF can be disabled
by setting bit 5 to 0 when  writing  to     $DF00-$DFFF. Cart ROM at
$8000-$BFFF can be disabled by setting bit  6     to 1 when  writing
to  $DF00-$DFFF.  Bit  7  of  a  byte  written  to     $DF00-$DFFF can
be read back from the cartridge  if  enabled  (like  a     memory cell).

This cart has 16Kb of ROM, of which the first  8Kb  is  mapped  in  at
  $8000-$9FFF and the second 8Kb is used as a  kernel  replacement.  The
   kernel replacement is achieved by a clip that needs  to  be
installed     inside the C64.

Reading from I/O-1 causes a capacitor to get charged with every  read,
  once the capacitor is charged enough it switches the cart on.

Reading from I/O-2 causes a different capacitor to  get  charged  with
  every read, once the capacitor is charged enough it switched the  cart
   off.

EasyFlash is a 1 MByte Flash EPROM card with  multiple  configurations
  and banks possible, it also has 256 bytes of RAM which is mapped  into
   the I/O-2 range.

There are two control registers, one at $DE00 and one at $DE02.

The register at $DE00 does the following:

    bit  meaning
    ---  -------
    7    LED control
    6-3  Unused
    2    Mode (0/1)
    1    Exrom line control
    0    Game line control

The register at $DE02 controls which bank  is  mapped  into  ROMH  and
  ROML.

This cart has 8Kb of ROM which is mapped to  $E000,  and  8Kb  of  RAM
  which is mapped to $6000. The cartridge is disabled after a reset.

When the freeze button is pressed the following happens:

   * an NMI is generated

   * as soon as the current adress is in bank 0xfe the cart  switches
     to       ultimax  mode.  The  cart  ROM  then  contains  one  page
     full   of       "jmp $eaea", which ultimately calls the freezer
     code.

   * the $FFF7/$FFF8 "register" logic is enabled and any access (read
     or       write) to $FFF7 will turn the cart_enabled off (leave
     ultimax mode),       and an access to $FFF8 will turn the cart
     back  on  (enter  ultimax       mode). the "register logic" that
     causes this can  only  be  disabled       again by a hardware
     reset.

The Retro Replay has three registers: Two write-only ($DE00  &  $DE01)
  and one read-only register ($DE00 & $DE01 giving the same results).

The register at $DE00 is reset to $00 on a hard reset if not in  flash
  mode. If in flash mode, it is set to  $02  in  order  to  prevent  the
   computer from starting the normal cartridge. Flash  mode  is
selected     with a jumper.

Register at $DE00:

    bit  meaning
    ---  -------
    0    Controls the GAME line: A 1 asserts the line, a 0  will  deassert
         it.
    1    Controls the EXROM line: A 0 will assert it, a  1  will  deassert
         it.
    2    Writing a 1 will disable further write accesses to all  registers
         of the Retro Replay, and  set  the  memory  map  of  the  C64  to
         standard, as if there is no cartridge installed at all.
    3    Controls bank-address 13 for ROM and RAM banking.
    4    Controls bank-address 14 for ROM and RAM banking.
    5    Switches between ROM and RAM: 0=ROM, 1=RAM
    6    Must be written once to "1" after a successful freeze in order to
         set the correct memory map and  enable  bits  0  and  1  of  this
         register. Otherwise no effect.
    7    Controls bank-address 15 for ROM banking.

The register at $DE01 is the extended  control  register.  If  not  in
  Flash mode, bits 1, 2 and 6 can only be  written  once.  If  in  Flash
   mode, the REUcomp bit cannot be set, but  the  register  will  not
be     disabled by the first write. Bit 5 is always set to 0 if not in
Flash     mode.

Register at $DE01:

    bit  meaning
    ---  -------
    0    Enable clockport connector.
    1    AllowBank (1 allows banking of RAM in $DF00/$DE02 area)
    2    NoFreeze (1 disables Freeze function)
    3    Bank-address 13 for RAM and ROM (mirror of $DE00)
    4    Bank-address 14 for RAM and ROM (mirror of $DE00)
    5    Bank-address 16 for ROM (only in flash mode)
    6    REU compatibility bit. 0=standard memory map, 1 = REU  compatible
         memory map
    7    Bank-address 15 for ROM (mirror of $DE00)

Reading from the registers at either $DE00 or $DE01  will  return  the
  content of the status register.

Status register:

    bit  meaning
    ---  -------
    0    1=Flashmode active (jumper set)
    1    feedback of AllowBank bit
    2    1=Freeze button pressed
    3    feedback of banking bit 13
    4    feedback of banking bit 14
    5    feedback of banking bit 16
    6    1=REU compatible memory map active
    7    feedback of banking bit 15

The following memory maps are available:

   * standard -     $DE00 and $DE01 registers are active,  $DF00-$DFFF
     contain  the  last     page of the selected 8Kb bank  of  either
     ROM  or  RAM,  whatever  is     selected. RAM can only be accessed
     in $8000-$9FFF. ROM can  be  mapped     to $8000, $A000 or $E000
     with the corresponding  status  on  GAME  and     EXROM.

     Note: If the AllowBank bit is  not  set,  the  $DF00-$DFFF  area
     will     always access bank 0 of the RAM, so the older  cartridge
     images  will     work. The AllowBank bit does not have any effect
     on the ROM mirror  in     that area.

   * Freeze -     ROM is mapped to $E000-$FFFF, bank 0 is active
     directly after  Freeze.      Writing to bits 0 and 1 of the $DE00
     register will have no  effect  on     GAME and EXROM. RAM can be
     selected  and  used  in  $DF00  or  $DE02,     respectively, but
     not in $8000. Banking bits work, so  you  have  full     read
     access to the ROM, and access to up to four RAM  pages  with  the
       AllowBank bit set (minus 2 bytes if REU compatible bit  is
     set).  You     should leave this memory map ASAP by setting bit 6
     of  $DE00,  because     C64 RAM in the $E000 area is not
     available, and you don't have control     of the GAME and EXROM
     lines.

   * REU compatible -     $DE00 and $DE01 registers are active,
     $DE02-$DEFF contain a mirror  of     $9E02-$9EFF of the selected
     8K-bank of either ROM or RAM, whatever  is     selected. RAM can
     only be accessed in $8000-$9FFF. ROM can  be  mapped     to $8000,
     $A000 or $E000 with the corresponding  status  on  GAME  and
     EXROM. The $DF00 stays free for use with the 1764 Ram  Expansion
     Unit     (REU).

     Note: If the AllowBank bit is  not  set,  the  $DE02-$DEFF  area
     will     always access bank 0 of the RAM, so the older  cartridge
     images  will     work. The AllowBank bit does not have any effect
     on the ROM mirror  in     that area.

This cart has 32Kb of ROM and 8Kb of RAM, it uses I/O-1 as a mirror of
  the last page of cart RAM. It has the following registers in the I/O-2
   range:

ROM config register at $DF00 (can only be written to):

    bit  meaning

    0    ?
    1    ? (write 1 to release freeze mode)
    2    ROM bank select
    3    write 1 to disable cartridge
    4-6  unused
    7    ?

Note: if bit0, bit1, bit7 are all 0, then ultimax mapping is  selected
  and RAM is enabled at ROML, otherwise if bit 0 is 0, then 16Kb mapping
   is enabled, or if bit 0 is 1, then 8Kb mapping is enabled.

RAM config register at $DF01 (read/write):

If written value == last value - 1, then ultimax mapping  is  selected
  and RAM is enabled at ROML, if written value == last value +  1,  then
   ROM is enabled at ROML and exrom is deasserted (switch to either 8k
or     16k mapping)

$DF02-$DFFF holds the last page of the first 8kb of the current bank.

When the cartridge is active, ultimax  is  enabled  when  the  address
  being accessed is is the $E000-$FFFF range, so the ROM is  visible  at
   $E000, below is normal C64 RAM. The cart can be disabled by writing
to     either I/O-1 or I/O-2 range. When the freezer button is
pressed,  the     cartridge will be enabled and an NMI will be
triggered.

Accessing I/O-1 (the software  uses  $DE00  only  it  seems)  disables
  cartridge ROM. A reset enables 8K game mode and the ROM bank is mapped
   to $8000. A freeze causes ROM to be mapped to $8000.

This cart has 64Kb ROM (2 32Kb Eproms, mapped to $8000  and  $A000  in
  16Kb Game Mode), and 32Kb RAM (mapped to $8000 and $A000 in  16K  Game
   Mode). The cart has 1 (write-only)  bank  control  register  which
is     located at $DE80 and mirrored throughout the $DE80-$DEFF range:

    Bit 0: unused/don't care
    Bit 1: Bank select: 0=upper, 1=lower (not correct ?!)
    Bit 2: chip select 0
    Bit 3: chip select 1
    Bit 4: cartridge enable/disable: 0=enable, 1=disable
    Bits 5-7: unused/don't care

Chip select combinations of 0/1 are:
    00: Eprom "79"
    01: Eprom "ZS3"
    10: Ram
    11: empty space (reading returns VIC-II data)

note: on the original hardware "disabling" the  cartridge  by  setting
        bit 4 of the control register does NOT prevent write accesses to
         the cartridge RAM!. So  to  actually  disable  the  RAM,  it
is           suggested to write $FF to the register.

18.1 VICE home page
===================

You can find the latest news about VICE at the official VICE home page:

http://vice-emu.sourceforge.net/

VICE has moved its source repository to public services provided by
SourceForge. You can find it at
http://sf.net/projects/vice-emu.

We would like to thank the SourceForge staff for that help.

If you are going to report a bug, please check those pages _first_; it
is possible that the problem you encountered has already been fixed
with a newer version.

Please, also have a look at the VICE knowledge base at

http://vicekb.trikaliotis.net/

18.2 How to send feedback
=========================

Before contacting us, have a look at the VICE knowledge base at
http://vicekb.trikaliotis.net/ if your question is answered there. Keep
in mind that we work on VICE in our spare-time, so the more time we
don't need to answer the same questions over and over again, the more
time we have to improve the emulation itself. On the other hand, that
does not mean that you should not contact us, especially if you find
bugs or have suggestions which might improve the emulation.

Bug reports, suggestions, support requests should be directed to the
SourceForge trackers at

   * http://sourceforge.net/tracker/?group_id=223021.

This way, you, the users, and we, the developers, can track what has
been reported and what has been already fixed. Ideally, also sent the
report to the mailing address of the Vice team at

   * VICE Mailing List (<vice-emu-mail@lists.sourceforge.net>) for all
     general questions, bug reports, suggestions.


You can also contact (some of) us on IRC, at #vice-dev on freenode.

It's always nice to receive feedback and/or bugreports about VICE, but
please read these few notes before sending mail to anybody in the team.

   * Please put the word `VICE' _in all capitals_ in your subject line
     (e.g., `VICE fails to run game XXX').  This helps mail splitting
     and reduces chances that your message is unintentionally deleted,
     forgotten or lost.

   * Please don't send any HTML mail (we really hate that!).  If you use
     M$ Outlook or Netscape Communicator, make sure you turn off the
     "rich text" (HTML) feature.

   * Please don't send _any_ binaries without asking first.

   * Please read the following documents carefully before reporting a
     bug or a problem you cannot solve:

        * the VICE documentation (you are reading it!);

        * the VICE FAQ (it is available on the Internet, and reachable
          from the VICE home page: http://vice-emu.sourceforge.net/);

        * The VICE knowledge base (it is available on the Internet at
          http://vicekb.trikaliotis.net/);

        * the `comp.emulators.cbm' and `comp.sys.cbm' FAQs (*note FAQs
          you should read::).

   * When you report a bug, please try to be as accurate as possible and
     describe how it can be reproduced to the very detail.  You should
     also tell us what machine you are running on, what operating
     system you are using as well as the version of it.

   * Please don't ask us how to transfer original C64 disk or tapes to
     your PC; this has been asked a gazillion times through email.  To
     transfer disks, you can use the Star Commander
     (http://sta.c64.org/sc.html) on DOS, and OpenCBM
     (http://www.trikaliotis.net/opencbm) on Windows and Linux.  And
     no, you cannot read C64 disks with your old 5"1/4 PC drive.

   * Please don't ask us where to find games for the emulator on the
     Internet.

   * Please don't ask us when the next version will be out, because we
     really don't know.

   * Please write in English.


In any case, we would be _really_ glad to receive your comments about
VICE.  We cannot always answer all the email, but we surely read all of
it.

Thanks!

18.3 How to contribute
======================

If you want to make a major contribution, please _ask_ first.  It has
already happened a couple of times that somebody started working at
something that had already been done but not released to the public yet,
and we really do _not_ want anybody to waste time.

If you are going to make a patch, please make sure the patch is relative
to the very latest version, and provide us with the following:

   * Make sure you are giving us a diff against the latest Subversion
     trunk version of VICE. For instructions on accessing the Subversion
     repository, first read http://sourceforge.net/svn/?group_id=223021
     and get it with the command:
     `svn co https://vice-emu.svn.sourceforge.net/svnroot/vice-emu/trunk vice-src'

   * send a unified diff file against the trunk version of VICE (see
     above bullet point) by using the command: `svn diff' inside of the
     SVN workspace you checked out before.

   * If you cannot use SVN for one or the other reason, send a unified
     diff file containing all the changes you have made `diff -u';
     please don't use plain `diff'), as it adds much work for us to get
     it working;

   * GNU-style `ChangeLog' entries with a description of the changes you
     have made (look at the `ChangeLog's provided with the original VICE
     sources for an example).

This is very important, and makes adding patches much smoother and
safer.

People willing to port VICE to other platforms are always welcome.  But
notice from experience it will take at least a full year of continuous
work to write a well working and stable port.

18.4 Interesting newsgroups
===========================

There are some Usenet newsgroups you might be interested in:

   * `comp.emulators.cbm', discussing about emulators of Commodore 8-bit
     machines (definitely not Amiga emulators).

   * `comp.sys.cbm', discussing various topics regarding real Commodore
     8-bit machines.  This newsgroup is mainly for people who actually
     use original Commodore equipment (so please don't talk about
     emulation here).

   * `comp.emulators.misc', discussing emulators in general.



File: vice.info,  Node: FAQs you should read,  Prev: Newsgroups,  Up: Contacts

18.5 FAQs you should read
=========================

We recommend reading the `comp.emulators.cbm' and `comp.sys.cbm' FAQs,
which are posted regularly on the corresponding newsgroups and are also
available via FTP from ftp://rtfm.mit.edu.
