README.md

Super Mario 64 Port

  • This repo contains a full decompilation of Super Mario 64 (J), (U), and (E) with minor exceptions in the audio subsystem.
  • Naming and documentation of the source code and data structures are in progress.
  • Efforts to decompile the Shindou ROM steadily advance toward a matching build.
  • Beyond Nintendo 64, it can also target Linux and Windows natively.

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

Building native executables

Linux

  1. Install prerequisites (Ubuntu): sudo apt install -y git build-essential pkg-config libusb-1.0-0-dev libsdl2-dev.
  2. Clone the repo: git clone https://github.com/sm64-port/sm64-port.git, which will create a directory sm64-port and then enter it cd sm64-port.
  3. Place a Super Mario 64 ROM called baserom.<VERSION>.z64 into the repository's root directory for asset extraction, where VERSION can be us, jp, or eu.
  4. Run make to build. Qualify the version through make VERSION=<VERSION>. Add -j4 to improve build speed (hardware dependent based on the amount of CPU cores available).
  5. The executable binary will be located at build/<VERSION>_pc/sm64.<VERSION>.f3dex2e.

Windows

  1. Install and update MSYS2, following all the directions listed on https://www.msys2.org/.
  2. From the start menu, launch MSYS2 MinGW and install required packages depending on your machine (do NOT launch "MSYS2 MSYS"):
  • 64-bit: Launch "MSYS2 MinGW 64-bit" and install: pacman -S git make python3 mingw-w64-x86_64-gcc
  • 32-bit (will also work on 64-bit machines): Launch "MSYS2 MinGW 32-bit" and install: pacman -S git make python3 mingw-w64-i686-gcc
  • Do NOT by mistake install the package called simply gcc.
  1. The MSYS2 terminal has a current working directory that initially is C:\msys64\home\<username> (home directory). At the prompt, you will see the current working directory in yellow. ~ is an alias for the home directory. You can change the current working directory to My Documents by entering cd /c/Users/<username>/Documents.
  2. Clone the repo: git clone https://github.com/sm64-port/sm64-port.git, which will create a directory sm64-port and then enter it cd sm64-port.
  3. Place a Super Mario 64 ROM called baserom.<VERSION>.z64 into the repository's root directory for asset extraction, where VERSION can be us, jp, or eu.
  4. Run make to build. Qualify the version through make VERSION=<VERSION>. Add -j4 to improve build speed (hardware dependent based on the amount of CPU cores available).
  5. The executable binary will be located at build/<VERSION>_pc/sm64.<VERSION>.f3dex2e.exe inside the repository.

Troubleshooting

  1. If you get make: gcc: command not found or make: gcc: No such file or directory although the packages did successfully install, you probably launched the wrong MSYS2. Read the instructions again. The terminal prompt should contain "MINGW32" or "MINGW64" in purple text, and NOT "MSYS".
  2. If you get Failed to open baserom.us.z64! you failed to place the baserom in the repository. You can write ls to list the files in the current working directory. If you are in the sm64-port directory, make sure you see it here.
  3. If you get make: *** No targets specified and no makefile found. Stop., you are not in the correct directory. Make sure the yellow text in the terminal ends with sm64-port. Use cd <dir> to enter the correct directory. If you write ls you should see all the project files, including Makefile if everything is correct.
  4. If you get any error, be sure MSYS2 packages are up to date by executing pacman -Syu and pacman -Su. If the MSYS2 window closes immediately after opening it, restart your computer.
  5. When you execute gcc -v, be sure you see Target: i686-w64-mingw32 or Target: x86_64-w64-mingw32. If you see Target: x86_64-pc-msys, you either opened the wrong MSYS start menu entry or installed the incorrect gcc package.
  6. When switching between building for other platforms, run make -C tools clean first to allow for the tools to recompile on the new platform. This also helps when switching between shells like WSL and MSYS2.

Debugging

The code can be debugged using gdb. On Linux install the gdb package and execute gdb <executable>. On MSYS2 install by executing pacman -S winpty gdb and execute winpty gdb <executable>. The winpty program makes sure the keyboard works correctly in the terminal. Also consider changing the -mwindows compile flag to -mconsole to be able to see stdout/stderr as well as be able to press Ctrl+C to interrupt the program. In the Makefile, make sure you compile the sources using -g rather than -O2 to include debugging symbols. See any online tutorial for how to use gdb.

ROM building

It is possible to build N64 ROMs as well with this repository. See https://github.com/n64decomp/sm64 for instructions.
