Mario Kart 64 Multiplayer
MP is currently not functional. PR's accepted. Please open an issue if a bug is found. Functionally equivallent code is accepted. All code must be inspired from legitimate sources and analysis of the game.
Requires: https://github.com/Henrik0x7F/lan64/tree/master/n64 in src/network/
Current progress:
- Supports up to eight human or computer players in single player GP mode.
- Game logic allows all eight players to cross finish line without failing.
- Eighth player is forced to complete the race by turning into a CPU.
Todo:
- Skip certain menu elements
- Pause at end of races until everyone is ready to continue
- Possibly edit ending sequence but it should be okay.
- Make race end regardless of where the eighth player is on the map.
- Prevent character scrolling banner from popping up until all players have finished.
Extras:
- Possibly balance kart stats
This repo contains a work-in-progress decompilation of Mario Kart 64 (U). The project pursues historical and educational elements found within the game via taking it apart and putting it back together. Inspiration to do so not only emanates from the game's hardware and technology but also its immensely positive effects on the cultures and families of nearly every nationality. See progress for more information.
It builds the following ROM:
- mk64.us.z64
sha1: 579c48e211ae952530ffc8738709f078d5dd215e
This repository does not contain assets. Compiling requires asset extraction from a prior copy of the game.
Dependencies
The build system has the following package requirements:
binutils-mips >= 2.27
python3 >= 3.6
libaudiofile
qemu-irix
Debian / Ubuntu
sudo apt install build-essential pkg-config git binutils-mips-linux-gnu python3 zlib1g-dev libaudiofile-dev
Building
Place a US version of Mario Kart 64 called baserom.us.z64
into the project folder for asset extraction.
Run the following commands after pulling:
- make -C tools
- make
Progress
The Mario Kart 64 code-base contains thirty-six C files, around twenty-eight files remain for decompilation. This does not account for other kinds of files such as data. The source is in an experimental 'shiftable' state that may allow modding but glitches and crashes are prevalent and the code-base will alter significantly overtime. As such, feedback that raises awareness of new issues are welcome. Please review issue #1 prior to issue submission to avoid duplicates.
