good luck there. emulating the Nintendo 64 is pretty much pushing the raspberry pi to capacity. I'm not sure if anyone on these forums have gotten it running correctly. The architecture of the N64 makes it hard to emulate correctly. Don't get me wrong, it can be done (to an extent). I would maybe check out this post if you are determined to get it working. http://www.raspberrypi.org/forums/viewtopic.php?t=58395
