I had a soft modded 4.0u Wii. I used Nintendo to update to 4.2 via the system menu. (Yes, i'm new to this). Everything went fine (I didn't mind losing my homebrew and backup loader options) but now out of all of my games, only Mario Kart Wii will not load up. It hangs on a black screen. I was told that I needed to reinstall IOS36 (?) I tried going through the steps of "bannerbombing" my Wii from a different site and after I said yes to booting the boot.dol my Wii hung on a black screen and won't do anything. I would greatly appreciate any help! I also tried the update on this site with the same result.
