Hi, I have an orginal GOW2 disc and my PS2 has mod chip that reads backup D9. I have tried to backup the disc but failed, after that, I read several threads about how to backup. Here is my brief idea, please correct me if I am wrong, thanks!! 1) Make the ISO using DVD Decrepter 2) Burn the .MDS using Nero/Alchol 120%, by changing the book type into DVD-ROM, select the lowest speed, of course write into a blank D9 3) Try to run the disc in my PS2 Please comment, thanks!!!
