Hi....my son's PS2 (v9) was chipped at the weekend (Duo 2 chip). I've used my Sony DRU-500A CD-RW to burn a couple of back up discs using DVD Decrypter - ISO Read, then ISO Write, burned at 1x. The discs used for both games (Formula one 2001 and Timestoppers 2) were Ritek GO4s and didn't work. I also tried a Bulkpaq (Princo) to burn Formula one 2001. In all cases the PS2 came up with a Disc Read Error message. The PS2 works fine with original media. This is my first attempt to backup PS2 games and I'm wondering where to go from here.....back to the chipper? Any advice gratefully received. Thanks in advance.
