The other day, my brother installed some cIOS in our wii. It was working just fine, but since then, several games stoped working properlly. For example, some tracks of Mario Kart brings up the black screen...
I´ve been thinking, could he have installed bad CIOS where he shouldnt? Anyway, is it possible for someone to post a good dop mii syschek in order to me compare with mine? I could download / upgrade whatever is missing.
