Need help with PS1 cheats on PS2 7000 series
  • What Gameshark or Codebreaker version for PS1 games can be used on the PS2 7000 series?
  • To my knowledge any version should work for use with PSOne games on the PS2.
  • According to the descriptions of some of the Gamesharks for the PS1 on Ebay, not all of them will work on all models of the PS2. I had an issue where I bought a PS1 memory card (third party manufacturer) online and it would not work on my PS2. Found out I was better off buying the PS1 memory cards made by Sony. I didn't want to buy a PS1 Gameshark to use on my PS2 only to find out that it isn't compatible.
