Well, basically all you need to do is get an NES emulator that can make WAV dumps or maybe Setup your mic to record the audio on your computer (WAV dumps are easier), then open any ROM, turn off all but one of the audio channels (Pulse 1, Triangle, etc.), record only a few seconds of anything and then import the WAV into Fuity Loops as a Sliced Beat. Restart Fruity Loops, then go into the Sliced Beats folder in the Browser and pick one of the parts to put in a channel, which basically turns that small clip into a whole insturment for you. That's about all you need to know, really. Just talk to me on AIM or something if you're still confused. By the ways, you're songs kick ass ;)
