SNES9x GX is a Super Nintendo emulator for Wii and GameCube based on the PC emulator SNES9x 1.51. SoftDev is responsible for the original SNES9x 1.51 GameCube port, whose work was continued by crunchy2. Wii support was added by michniewski, and SNES9x 1.51 was ported by Tantric. The project is currently being maintained by michniewski and Tantric. The GUI is powered by libwiigui.
