I recently installed NeoGamma rev6. I burned a disc with one game, Twilight Princess, NTSC-U. It worked. Today, I burned a disc that has 3 games, each an iso file, each in their own folder directory. It gave me a disc read error. How do I run this disc? Is there a different loader that will do this? I cannot use USB, because of a lack of HDD space. I need it on a disc. Multiple games on each disc.
