I have been adding mods to smash bros like brawlEX, project M, and and brawl minus. Today I wanted to play vanilla brawl. I went on "my music" in the options and when I tried to go on battle field's songs, the game froze. So I tried playing a match on battle field, it works, but sometimes there wont be any music playing. All the other stages on "my music" work fine. I don't know why its doing this. It is a legit copy of brawl, I even took out the sd card and the problem is still there. Could I have corrupted a file on the disc? Has anyone else have this issue? Could this effect other stuff on the game as well? Any help would be appreciated. Thanks
