Today I put in an original Gamecube retail disc into my Wii and to my surprise it didn't work. So I tried a few more games, but with the same result. The games are recognized in the Wii menu, but when I start them it's just a black screen. Wii games still work. And Gamecube games used to work just fine. The only thing I did lately was installing DiosMios. Could this have something to do with it?
