MASHUP: MARIO GETS THE PORTAL GUN IN SUPER MARIO 64, AND YOU CAN BEAT THE WHOLE GAME WITH IT
Portal Gun for Super Mario 64 Co-op DX: Mario gets Aperture's portal gun and keeps his full moveset

Zombie1234's Portal Gun mod for sm64coopdx (the Super Mario 64 co-op project, which runs from your own ROM) drops Portal's signature tool into Mario 64: shoot blue and orange portals, fizzle them, and use them to get around while Mario keeps his normal movement. The creator says you can beat the full game with it. It went up on GameBanana on 1 November with a PC download and a separate mobile build. It's brand new and small so far, but it's a real playable crossover rather than a skin. Like the SkyCraft-style guest mods on our wire, it reuses an existing host (sm64coopdx) rather than a new engine.
You need: sm64coopdx set up with your own Super Mario 64 ROM. No game files are included in the mod.
How to play
- Set up sm64coopdx with your own Super Mario 64 ROM.
- Download the Portal Gun zip from the creator's GameBanana page and extract it into sm64coopdx's mods folder.
- Enable the mod when hosting a game, then shoot portals.
