Load GS2, Once it completely loads press eject and swap with a original dvd game.(i use DMC demo). Wait about 30 sec and select gameshark codes, choose any game and turn on or off any code. Then press start, select with codes and press x to load game, you will see a black screen that says updating codes please wait. Immediately do the r-mod swap by pressing and holding eject until the tray ejects, swap the original dvd game with the dvd-r backup, the tray will close after 5 sec and the backup will load.
Maybe this will help you guys out....
