Building

Place your copy of the original rom in the root folder of this repository and name it baserom.z64

Create a python virtual environment with python3 -m venv .venv. Then, activate it with source .venv/bin/activate and install the required packages with python3 -m pip install requirements.txt

With the python virtual environment active, run make all to configure and build the tools (only the first time), run splat and generate a new ROM in build/ridgeracer64.z64.

To run splat without building a new ROM, run make split
