Any import game would need it\'s own "enable" code to load BEFORE the game itself would load, and Interact (the makers of Gameshark) is in NO WAY going to list those codes.
The GS2 for the PS2 is NOT user "hackable" like the GSPro for the PSX, so the only codes you will get will be from Interact, unless, and until, someone breaks the "encryption" code that the GS2 uses for it\'s hex based codes.
Pelican is going to be releasing their "Code Breaker" that supposedly allows users to "Make their own" codes. It\'s slated for a March 16th release, but Pelicans site is devoid of any real info. I think it\'s just vaporware at this point, but we\'ll see.
