Super Mario 64 is a classic 3D platformer that came out on Nintendo 64. This Mario game was locked at 30fps and while some emulator could run the game with 60fps, they had incorrect/bugged physics. Thankfully, Kaze Emanuar released a new romhack/mod for Super Mario 64 that allows gamers to finally experience it with 60fps and proper physics.
