I just made a minor checkin to flag N64 as GAME_NOT_WORKING but remove GAME_IMPERFECT_SOUND, as I'm pretty sure the Rampage: World Tour audio issue is located DMADAC-side and not N64-side, and I don't know of any other games with incorrect audio.

I really don't want to add GAME_NOT_WORKING, especially since I can point to Bust-A-Move 2 or Rampage: World Tour as games that work fine, but with the number of weirdo crashes I'm getting even in run-of-the-mill games, I don't feel like lying to anyone about the state of the driver.
