I have a PS2 with a modchip installed (unknown to me) and I must perform the Gameshark disk swap (boot up Gameshark, take GS disk out of tray, insert back-up PS2 DVD game, hit "play without codes" , and go... Yet the other day I did an image copy of GTA: Vice City (A game I own, just backing up!) and when I tried this with my PS2 nothing happens..the disk spins but nothing loads up. I used Primo Prassi, a Sony DVD-RW, and a Panisonic DVD burner (DVDR 104). Question: What am I supposed to do to solve my problem? New disk (non dvd-rW maybe)? , different game? Can I just try to copy another game on the disk cause its DVD-RW or wont it work (like CDRW's). thanks!
