The emulator is planned to use dynamic recompilation of the N64 machine code to PowerPC machine code and full hardware accelerated graphics to achieve full-speed emulation. Currently the emulator is in beta stage and can run many N64 ROMs at near full speed.

The emulator can be controlled with any combination of GC controllers, Classic Controllers, and Wiimotes with Nunchuks (sorry, Wiimotes must have nunchuks). See the included readme for details on the controls. You can load ROMs and saves from a FAT formatted SD or USB (details on the folders required are in the readme).
