My Mario Kart Wii loaded perfectly from the disk channel. But since I am going to get a HDD soon I heard that cIOS Rev 14 would be better for it. So I ran the cIOS Rev 14 installer. When I went to the wii menu to play Mario Kart it said can't read disk. So I ran the cIOS Rev 13 ( the one that worked before ) again but didn't do any thing. So is there a way around this?
