SNES9X is a very popular open source emulator mainly for the PC platform, but
|
||||
has seen many ports to other consoles such as the Nintendo DS, Microsoft XBOX
|
||||
and now thanks to SoftDev the Nintendo GameCube! This is a straight port and
|
||||
is not based on any previous SNES emulators that have existed for the

GameCube. You can get more information on SNES9X here from the URL below:
