I just installed the cfw 3.55 kmeaw with a 500gb samsung drive and installed the five games that i have to internal. The games are god of war collection, god of war iii, metal gear solid 4, street fighter iv and uncharted. None of the games will launch. All I get is a black screen after i launch the games. I left the disk in the drive and nothing. What am i doing wrong? I read with an external drive you just press selct + X and it launches the game, but don't have an external at the moment.
