I use Kmeaw's 3.55 CFW to backup my games on the internal HDD and I use the original Uncharted 2 Blu-ray to run them. However, just recently I tried to play Uncharted 2 off the disc, but it seems there's a problem. The game will either load forever or it'll give a black screen. I ejected the disc several times, but it didn't work. I also tried to boot the game from Multiman Manager with no results. All the backuped games however run fine with no problem. Does anyone know what happened?
