PS2 DVD to DVD-R

[Warlock]

) Turned on the PS2 with GS2 Version 2 (holding down the ON/RESET)
2) once GS2 is loaded Press EJECT (while still holding the ON/RESET button) and swap GS2 with original dvd game
4) Press EJECT to close (Wait 15 seconds)
5) Then select Gameshark codes and turn on or off any code on any game, Press start, select with codes, and press x to load game. A black screen will appear saying "updating codes list please wait" Time you see this release the reset button, tray will eject, swap original dvd with backup, tray will close and backup will load.Nightstalker posted this method earlier. it seems if you are using GS2 v2x you must boot dvd-r with this method.
