No gameshark for the PC, but why would you need one? All games on the PC are easy to cheat on. Go to www.gamefaqs.com and look up whatever game you need. And if you are thinking of cheating in onlne games, that's the easiest way to get banned when they catch you. (For example on counterstrike, if you were caught cheating on UKnet they would ban your IP and share banned IP's which would basically rule out 95% of joinable games.)
