Port of the popular multi-OS N64 emulator, Mupen64, to the Nintendo Wii and Gamecube through the libOGC library. The emulator uses dynamic recompilation of the N64 machine code to PowerPC machine code and full hardware accelerated graphics to achieve (mostly) full speed emulation. Currently the emulator is in beta stage and can run many N64 ROMs at full speed in most cases.


Not64 is an "experimental modification" of Wii64, forked from the "Beta 1.1 'Honey'" version to include several fixes and additions.[1]

Not64 is available to download from the thread at GC Forever.

Further Information

The emulator can be controlled with any combination of GC controllers, Classic Controllers, Wiimotes with Nunchuks and even just Wiimotes. 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).


We don't want to discourage other people forking and working on the emulator; however, any unofficial builds must not be called "Wii64" or "Cube64" nor use the Wii64 or Cube64 logo in order to avoid confusion. For now, we're just releasing a snapshot of the source used to build Beta 1.1, but we're planning on updating the public repository with each commit we've made to our private repository so that everyone can see the progression of the code. This process will begin soon.

Quick Usage

Load the executable from the HBC or in the loader of your choice

Once loaded, select 'Load ROM'

Choose the source (SD/USB/DVD)

Select the ROM to load (Note: to go up a directory select '..', B will exit the file browser)

Select 'Play Game' to play

Wiimote 1 Button + Wiimote 2 Button Gamecube X Button + Gamecube Y Button Classic x Button + Classic y Button Wii RESET Button

(Note: this must be done to save your game; it will not be done automatically)



  • Native Saves Device: Choose where to load and save native game saves
