Hi I have checked the back of my PS2 and it says my serial code matches with that of version 4. Anyways I CANNOT find a Gameshark2 version 2 in ANY stores. I can find the Action Replay MAX with 8MB memory card. I am not allowed to order online, so I can't get SWAP Magic I heard about problems with Gameshark2v3 and how about AR MAX? Please I need information on this, none of the stores have used GS2v2's either.
