You can find the keyboard controls on the drop-down instructions card right here. For instance, the A button has been mapped to X and the B button is the C button on the keyboard. However, it is worth mentioning that the keyboard controls are a bit different than the old Nintendo 64 buttons. The game, in my experience, ran perfectly fine with smooth animations, and fun gameplay. Now, as I do not have a compatible controller at the moment, I tried the Super Mario 64 on my MacBook Air. So, if you start a game on your iPhone, you can pair an Xbox, Playstation, or an MFi controller to your iOS device. However, it is important to note that you will need to connect a compatible controller to play the game on your devices.
