Wii64 is a port of the popular multi-OS N64 emulator, Mupen64, to the Nintendo Gamecube and Wii through the libOGC library. The emulator is planned to use dynamic recompilation of the N64 machine code to PowerPC (the Gamecube/Wii's ISA) and full hardware accelerated graphics to (hopefully) achieve full-speed emulation.
