zsnes (SNES emulator) ZSNES is a Super Nintendo emulator programmed by zsKnight and _Demo_. On April 2, 2001 the ZSNES project was GPL'ed and its source released to the public. It currently runs on Windows, Linux, FreeBSD, and DOS. The original zsnes developers' last release was 1.51, in 2007. This build is for xyproto's fork, which is still maintained as of 2026, and now supports CPUs other than 32-bit x86. Build options (environment variables): - AO=no - disable libao for audio output. Removes all audio output drivers except SDL. Probably not useful. - DEBUGGER=no - disable the built-in debugger. May give a slight speed boost on old/slow systems.
