i used modmii to update my ios's on my 4.3u. i done a system check then run it in modmii and it told me what ios's i needed to update. after i updated the wii ios's some of my backup games on dvd-r stopped loading. mostly music games (rockband 3 all guitar hero's) , all instruments and a few others (call of duty's). somehow my backup wad file got deleted. so i dont know what ios's i had that worked. can anybody help? thanks .
