SM64: The Parallel Universes is a ROM hack of Super Mario 64 for the Nintendo 64, which likely introduces multiple parallel universes or alternate realities. Super Mario 64 was known for its distinct levels and worlds. This ROM hack takes that concept further by introducing multiple parallel universes with their own unique designs and challenges. Expect a lot of new level design and altered game environments.  The gameplay would still center around collecting stars and exploring 3D environments but would introduce new level layouts and visual design in these new parallel universes. This is a fan-made game modification adding a new dimension to the original game.
