Game Shark!!?
 

I went to ChipZone ti try to get a mod chip for my PS2. On all of the chip descriptions it says that you also need to buy a gameshark to play PS2 backup games? Whats up with that? Do i need to get gameshark for every mod chip out there for PS2? Please e-mail me at [email protected] if you know all of these things. I would greatly appreciate that. Thanks.
