So I'm new to this, please bear with me. I've used WiiBackupManager to put some ISOs (now in wbfs format) onto a USB drive. When I open up the drive in Wiiflow, it recognizes the games perfectly fine. But when I try to play them, it freezes with a black screen and spits out whatever disc is in the disc drive. Or if there isn't a disc, it makes the sound like its trying to load one. What can I do to fix this? Thanks in advance for the help!
