Mupen64GC is a port of Mupen64 for the Gamecube/Wii. Mupen64 is a popular multi-OS N64 emulator.

The emulator is planned to use dynamic recompilation of the N64 machine code to PowerPC (the Gamecube’s ISA) and full hardware accelerated graphics to (hopefully) achieve full-speed emulation.

For now just the source code is available. A binary seems to be available at http://www.dcemu.co.uk/vbulletin/showthread.php?t=75428
