So I realized pretty quick after turning it on that he'd done some hacking to the wii (plus some of the games he gave me were clearly copied discs). I restored best I could (Format Wii System Memory) trying to make it as close to new as possible. Everything was fine and dandy until I realized that most of my wii discs would not play! The show up in the disc reader, but when I select them and hit 'Start' the screen goes black, remotes turns off, and I have to reset the wii. I know the disc is fine and I don't get any disc read error, just the black screen. Anyone have any idea what he did and how I can undo it?
