Mario in the Multiverse
スーパーマリオ64
A large team-made Super Mario 64 hack in which Mario hops between worlds inspired by other games and franchises, each course built by a different group of hackers but tied into one adventure.
What it is
Mario in the Multiverse is a collaboration led by rovertronic with many well-known Super Mario 64 hackers. Every course takes Mario into a world modelled on a different game or series, often with its own mechanics, enemies and bosses, and they are linked into a single story with a hub and a final boss.
Versions
The first full release came out in December 2024. Version 1.1.0 followed days later with a long list of fixes, and version 1.1.1 (May 2025) polishes course 4 and the crane camera of course 3, makes one item snap to 45-degree angles, and improves the final boss's hitboxes and music sync.
Playing it
Apply the patch to your own copy of Super Mario 64 (USA), following the instructions with the release on the project's GitHub page, which also hosts the source. The team recommends Parallel Launcher; the game shows a warning on Project64 and on real hardware, where it is not optimised. Full credits are in the game.
