I remember this old rigger was for just fooling around back when NES was about. Then they made one for Playstation and what not (They stopped producing them after they saw what people were doing).
If no one knows what Gameshark is. It is an old thing you could buy in stores (Think you still can somewhere)put it on your PS2 or whatever and it would do cheats, coding, etc, (whatever you want to call it) for you. They even had one for PS2. So, could anyone clarify that Gameshark is literally that compatible with Battlefield 2 and/or Socom and all that?
