We keep my N64 at my grandmas and I really wanna play some N64 so I downloaded an emulator and some games. I have a few problems. The only two emulators for mac are Mupen64 (it runs great but you can't change the controls) and sixtyforce (runs like shit). So now I downloaded Project64 inside my windows xp virtualbox. But that doesn't work because it says there's no drivers. I'm assuming that problems just stems from the fact that I'm running virtualbox and not actual windows? Can anyone help me in any of the following ways?:

1. Is there a way to change the controls in Mupen64?
2. How can I get Project64 to run? Do I just install the windows drivers while in virtualbox?
3. Is there anymore emulators for mac that I don't know of?

Please help!
