I've been having problems with my Wii regarding disc-reading. It seems to have completely stopped reading most of my game discs. My gamecube discs work fine, but they give me disc-read errors. As for Wii games, only a small amount of them work, and some of them, even though they're recognized by the Wii, refuse to load. I'm not sure it's the drive itself, because when I insert my WiiKey update disc, it reads it instantly. I'm on 4.2U and I have bootmii installed. I have no clue which revision of cIOS I have installed.
