MarioKart64JS is a fan rebuild of Mario Kart 64 that runs in a browser tab. AgentiLoop used AI agents to port the decompiled original (the n64decomp/mk64 project) to JavaScript and Three.js, so there is no emulator. All 16 courses, items, drifting with mini-turbo and the original music are in.
Pick 2P, 3P or 4P GAME to race other people online: a room starts when it fills up or 15 seconds after the first player joins, and CPU karts take any empty seats. Press G for sharper resolutions and HD textures, or 3 for Wii-style 3D karts. Keyboard or gamepad.
