The Harbour Masters have developed a native PC port of Mario Kart 64 called SpaghettiKart, allowing players to race without an emulator. Users must provide their own legally acquired ROM to comply with copyright laws. The project is still in development, featuring some bugs and crashes. The Harbour Masters are known for successful ports of other classic games, like Starfox 64. Detailed instructions and information about the required ROM can be found on the project's GitHub page.
