Yes. There's no other way to play it. You have to take the original Super Mario 64 game, modify it, and run the modded rom in an emulator.
I also have another game to share. It's not out yet, but it will be by the end of the week.

This is a great crossover involving just the normal characters and levels, but the twist this time is that Mario's got himself a Portal Gun! It comes out in just over 4 days! I can't wait.
