Starfox 64 (US) REV 1.1
This is a WIP matching decompilation of Starfox 64. The purpose of the project is to recreate a source code base for the game from scratch, using information found inside the game along with static and/or dynamic analysis.
It currently builds the following ROM:
- starfox64.us.z64
MD5: 741a94eee093c4c8684e66b89f8685e8
This repo does not include any assets or assembly code necessary for compiling the ROM. A prior copy of the game is required to extract the required assets.
Installation
1. Install build dependencies
Windows
For Windows 10, install WSL and a distribution by following this Windows Subsystem for Linux Installation Guide. We recommend using Debian or Ubuntu 22.04 Linux distributions.
Linux (Native or under WSL / VM)
The build process has the following package requirements:
- make
- git
- build-essential
- binutils-mips-linux-gnu
- python3
- pip3
- libpng-dev
Under Debian / Ubuntu (which we recommend using), you can install them with the following commands:
sudo apt update
sudo apt install make git build-essential binutils-mips-linux-gnu python3 python3-pip clang-format-14 clang-tidy
MacOS
Install Homebrew and the following dependencies:
brew update
brew install coreutils make pkg-config tehzz/n64-dev/mips64-elf-binutils
2. Clone the repository
Create your own fork of the repository at https://github.com/sonicdcer/sf64. Then clone your fork where you wish to have the project, with the command:
git clone https://github.com/<YOUR_USERNAME>/sf64.git
This will copy the GitHub repository contents into a new folder in the current directory called sf64. Change into this directory before doing anything else:
cd sf64
3. Install python dependencies
The build process has a few python packages required that are located in /tools/requirements-python.txt.
To install them simply run in a terminal:
python3 -m pip install -r ./tools/requirements-python.txt --break-system-packages
4. Update submodules & build toolchain
git submodule update --init --recursive
make toolchain
5. Prepare a base ROM
Copy your ROM to the root of this new project directory, and rename the file of the baserom to reflect the version of ROM you are using. ex: baserom.us.z64
6. Make and Build the ROM
To start the extraction/build process, run the following command:
make init
This will create the build folders, a new folder with the assembly as well as containing the disassembly of nearly all the files containing code.
this make target will also build the ROM. If all goes well, a new ROM called "starfox64.us.z64" should be built and the following text should be printed:
741a94eee093c4c8684e66b89f8685e8 build/starfox64.us.z64
./build/starfox64.us.z64: OK
If you instead see the following:
./build/starfox64.us.z64: FAILED
md5sum: WARNING: 1 computed checksum did NOT match
This means that something is wrong with the ROM's contents. Either the base files are incorrect due to a bad ROM, or some of the code is not matching.
From now on you should be able to build the rom by running make.
