So, I wanted to start from scratch on this Wii I just bought from a friend and the first thing I did was updated it to 4.2U after I installed bootmii, then I made a backup and opened it with showmiiwads and said "huh ??" I don't know what this guy did or the guy before him, they're both crackheads. I need help identifying this Japan stuff and a way to delete it. any suggestions ?
