A in-progress decompilation of Gauntlet Legends

Building (Linux)

Install build dependencies

The build process has the following package requirements:

• git
• build-essential
• binutils-mips-linux-gnu
• python3
• ninja-build

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 ninja-build

Clone the repository

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 https://github.com/Drahsid/gauntlet-legends.git
git submodule init

Install Python3 requirements

Run pip3 install -r tools/splat/requirements.txt

Prepare the tools

Just run ./build.py initial

Prepare the base rom

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

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