Rom Top | Super Mario 64 Coop Dx

When one player hits a block or collects a Power Star, the state of the world updates for everyone in real-time.

Large groups can join a single session, turning the game into a chaotic, fun multiplayer experience.

Super Mario 64 Coop DX (sm64coopdx) is a source-available mod for the fan-made Super Mario 64 PC port. This project restructures the original game to support online cooperative gameplay for up to 16 players, who can play through the entire campaign together, unlike older projects which were more unstable or less feature-rich.
