About

SpaghettiKart is a PC port of Mario Kart 64 built from the MK64 decompilation on HarbourMasters' libultraship (maintainers MegaMech, Coco and Kirito). It adds widescreen, high frame rates, modern controls and mod/custom-track support.

No game assets are included. smog copies your own US ROM (.z64) into the install folder, and on first launch SpaghettiKart builds its mk64.o2r asset archive from it. The archive, saves and settings are kept in smog's persistent per-entry folder, so they survive updates.
