WARNING: VERY BAD GAMEPLAY
So, I decided to try out SM64 Co-op Deluxe, and of course I had to start with the mod that perked my interest in this game to begin with.
The MMX mod for Coop DX adds in X, Zero, Vile, and in a future version, Axl. They're all pretty fun to play with, but Zero has to be my favorite so far. No wonders there, it's Zero after all, he's always fun to play.
I decided to record me getting all the stars in LLL in a single run, since DX lets you continue a stage after getting a star. (almost all the stars * I accidentally picked up the 2nd star in the volcano, and the game auto saves even if I pick "No")
