Why can I rotate the camera left in Mario and other games, and why doesn the left d-pad button work correctly??
The key for left camera (left-c) is incorrectly mapped to the “F” key. The control setup screen shows that it should be mapped to the “J” key, but it is not. Unfortunately, the “F” key is also used for left on the d-pad (digital pad). This makes Pushing left on the D-pad impossible with the default keys. In games where you have the choice of using the d-pad or the analog pad, always use the analog, as it is correctly mapped to the arrow keys. You can use “F” for left-c, but another (better) solution is to use a nice little utility made by Furon called HLEconfig. This utility allows you to remap most of the buttons of the N64 controller to different keys than the emulator defaults to. Using this program, you can get the left-c button correctly mapped to “J”, or whatever else you might want.
