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 dramatically since its last version (1.51 released on 24 January 2007). The emulator became free software under the GPL-2.0-or-later license on 2 April 2001. Since then, official ports have been made for Windows and Linux. Development of ZSNES began on 3 July 1997 and the first version was released on 14 October 1997, for DOS.
