I backed up Syphon Filter: Omega Strain using dvd-decrypter and i use a flip top with Swap magic dvd 2.0 It does boot up ok but when sometimes it just hangs every now and then on some loading screens or when i start a mission...... and it skips like crazy on the intro movie. I have a version 1 ps2 (yeah its so old its ancient) and i haven't had any other problems with other backed up games. is anyone having the same problem ???
