Super Mario 64

This repo contains a full decompilation of Super Mario 64 (J) and (U). The source and data have been decompiled but complete naming and documentation all of the code and data is still a work in progress. Decompiling the (E) ROM is also an ongoing effort.

It builds the following ROMs:

  • sha1: 8a20a5c83d6ceb0f0506cfc9fa20d8f438cafe51
  • sha1: 9bef1128717f958171a4afac3ed78ee2bb4e86ce

This repo does not include all assets necessary for compiling the ROMs. A prior copy of the game is required to extract the required assets.



1. Copy baserom(s) for asset extraction

For each version (jp/us/eu) that you want to build a ROM for, put an existing ROM at ./baserom.<version>.z64 for asset extraction.

2. Install build dependencies

The build system has the following package requirements:

  • binutils-mips >= 2.27
  • python3 >= 3.6
  • libaudiofile
  • qemu-irix

Debian / Ubuntu

sudo apt install build-essential pkg-config git binutils-mips-linux-gnu python3 zlib1g-dev libaudiofile-dev

Download latest package from qemu-irix Releases

sudo dpkg -i qemu-irix-2.11.0-2169-g32ab296eef_amd64.deb

(Optional) Clone and follow the install instructions in the README.

Arch Linux

sudo pacman -S base-devel python audiofile

Install the following AUR packages:

3. Build ROM

Run make to build the ROM (defaults to VERSION=us). Make sure your path to the repo is not too long or else this process will error, as the emulated IDO compiler cannot handle paths longer than 255 characters. Examples:

make VERSION=jp -j4       # build (J) version instead with 4 jobs
make VERSION=eu COMPARE=0 # non-matching EU version still WIP


For Windows, install WSL and a distro of your choice following Windows Subsystem for Linux Installation Guide for Windows 10 We recommend either Debian or Ubuntu 18.04 Linux distributions under WSL.

Then follow the directions in the Linux installation section above.


macOS is currently unsupported as qemu-irix is unable to be built for macOS host. The recommended path is installing a Linux distribution under a VM.
