A in-progress decompilation of Gauntlet Legends

The build process has the following package requirements:

• git
• build-essential
• binutils-mips-linux-gnu
• python3
• python3-pip
• python3-venv
• ninja-build
• cargo
• wget

Under a Debian based distribution, you can install these with the following commands:

sudo apt update
sudo apt install git build-essential binutils-mips-linux-gnu python3 python3-pip python3-venv ninja-build cargo wget

Clone https://github.com/Drahsid/gauntlet-legends.git in whatever directory you wish. Make sure to initialize the submodules!

git clone https://github.com/Drahsid/gauntlet-legends.git --recursive
cd gauntlet-legends
git submodule update --init --recursive

Create and activate a virtual environment before installing the Python requirements:

python3 -m venv .venv
. .venv/bin/activate
python -m pip install --upgrade pip
python -m pip install -r requirements.txt

Keep the virtual environment active when running build.py or run build commands through .venv/bin/python, for example .venv/bin/python build.py initial.

Run python3 ./build.py initial. This builds n64crc, downloads the KMC GCC package used by the build, and installs the slinky-cli executable if it is not already on your PATH.

Copy over your copy of Gauntlet Legends US into the root folder of this repository. Rename the rom to baserom.z64.

Next, run python3 ./build.py setup to extract the assets of the rom.

Run python3 ./build.py to build the rom. If the build succeeds, a folder will be produced with the name build, inside this will be the output rom gauntlet.z64.

Addtionally, if the rom matches, you should see this output:

BootChip: CIC-NUS-6102
CRC 1: 0x729B5E32  Calculated: 0x729B5E32 (Good)
CRC 2: 0xB728D980  Calculated: 0xB728D980 (Good)
boot: OK!
Tower: OK!
Transitions: OK!
Boss: OK!
game: OK!
