I got one to blow thru Resident Evil 4 on PS2 to play the Ada part that I did not get to play on the gamecube. I usally don't cheat but I had already played thru Leon's part of RE4 about a billion times on the Gamecube and just wanted to play the part they added to RE4 for PS2. Which you can't do til you beat Leons part. So I figured I would get a Gameshark and use the codes and breeze thru it so I could. Well the fucking Gameshark is shit. Says you can use a pen drive well that does not work nor did tech support know how to get it to work. Can't get the thing to connect to the net it will not connect to a network or connect to the site always get bad login. I picked up a codebreaker today and the fucking thing connected to the net and got the codes I want no trouble at all. So I did this to the GameShark and posted it to there site.
I thought Codebreaker and Gameshark were made by the same company. It might be Pro-Action Replay I'm thinking of though. I've never had a problem with mine, but at the same time I work in a gaming center.
