So far I have had the following games that won't play, it just comes up to insert a PS2 format disc. Ghost Recon Advanced Warfighter Fatal Fury Shellshock Nam 67 Battlefront 2 All are originals, I even took Battlefront 2 back the the store and exchanged it twice so I tried 3 different copies and they all wouldn't play. So it seems like some kind of problem reading certain games. Has anyone else had this kind of problem? Any idea why certain games just refuse to play in my PS2? It is a version 7 PS2. I did try cleaning the lens. Thanks.
