I recently downloaded a Punch Out (Wii) ISO, and burned it. I tried to play it through the disc channel (with cMIOS installed), but it gived me the "Unable to read the disc." prompt. All of my other discs work except for this and NSMBWii, but NSMB is what I am not focusing on right now. I want to also be able to play on a regular backup launcher, but NONE of the backup launchers work for me. GCN backup launchers, do work however.
