Matching decomp of Dr. Mario 64

Dependencies

All the instructions assume the user is using a Debian/Ubuntu based Linux distro. If you are a Windows user then it is recommended to use WSL2 with Ubuntu.

System packages

The build process has the following package requirements:

• make
• git
• build-essential
• wget
• clang
• binutils-mips-linux-gnu
• gcc-mips-linux-gnu
• uv

Under Debian / Ubuntu (which we recommend using), you can install most of them with the following commands:

sudo apt update
sudo apt install make git build-essential wget clang binutils-mips-linux-gnu gcc-mips-linux-gnu

uv

We use uv to manage Python and its dependencies.

See the official uv docs to install it: https://docs.astral.sh/uv/getting-started/installation/

Then run uv sync to install and update Python and any dependency needed.

If you need to run any Python script directly you can use either uv run ./script.py or enable the venv in your shell.

Building

Copy your big-endian Dr Mario 64 ROM into the repository's config/us directory and rename it to baserom.us.z64. Then run the following commands to download the appropriate compiler versions, extract ROM data using splat, and build the files back into a rom.

You can pass -j N, where N is the number of cores your processor has (you can know this value by using nproc), to speedup the build by parallelizing.

make setup
make extract
make

If successful, the last line of output should say:

build/us/drmario64.us.z64: OK

Other versions

This repository has support for the iQue and the Gateway versions of this game.

To build any of those versions place the corresponding ROM in the config/cn/ or config/gw directories of the repo and rename the rom to either baserom.cn.z64 or baserom.gw.z64, cn corresponding to the iQue version, while gw corresponds to the Gateway one. Run the above make commands but pass either VERSION=cn or VERSION=gw to build each version respectively.

Contributing

TODO: write some contributing guidelines.

Smaller efforts are appreciated. Just open a PR and try to address any review comments left by other contributors c:

This repository takes some heavy inspiration from the DWARF debug information dumped from the Gamecube release. You can access the DWARF dump in this repository: https://github.com/AngheloAlf/puzzle_collection_dwarf

Important note

This matching decomp effort is being done leak-free. If you have looked/worked with leaked materials (i.e. gigaleak) then it's a shame but you can't contribute to this project.

License

This repository is licensed under the MIT license, except for

• files which declare a different license, and
• folders that have their own LICENSE file.

In such cases that license takes precedence.

In particular, the src/ folder is licensed under the CC0 license.

N.B.

The intention of this project is to understand the inner workings of this game better, and to make it easier to modify its behaviour.

As such, over and above the actual licensing of the repo, the decomp team requests that this codebase not be used to build binaries targeting non-MIPS machines ("porting").
