ZSNES is a free software Super Nintendo Entertainment System emulator written mostly in x86 assembly with official ports for Linux, DOS, Mac OS X, Windows, and an unofficial port for Xbox.
Development of ZSNES began on 3 July 1997 and the first version was released on 14 October 1997, for DOS. Since then, official ports have been made for Windows and Linux. The emulator became free software under the GPL license on 2 April 2001. Despite an announcement by adventure_of_link stating that "ZSNES is NOT dead, it's still in development" made on the ZSNES board after the departure of its original developers zsKnight and _Demo_, development has slowed down dramatically since its last version (1.51 released on 24 January 2007). Much of the development efforts concentrated on increasing the emulator's portability, by rewriting assembly code in C and C++, including a new GUI using Qt.
ZSNES is notable in that it was among the first to emulate most SNES enhancement chips at some level. Until version 1.50, ZSNES featured netplay via TCP/IP or . The way sound is emulated in ZSNES is different compared to other Super NES emulators (e.g. Snes9x), or an actual Super NES hardware.
Due to being written in low-level assembly language for x86 processors, it is not possible to port ZSNES to devices using RISC processors. Other than the original Xbox, no mainstream gaming console has ever used an x86 processor prior to the eighth generation, with the 2013 releases of the Xbox One and PlayStation 4.
