Query: Way Cool, But be careful what codes you use.

I have a few things to say about Gameshark Pro. Number 1, it can make the game you are using much more fun. 2, It DOES NOT have to take all the fun out of the game, you CAN choose the codes you use. (I myself think codes like invincibility are cheap, but Gameshark has other codes.) 3, Use codes ONLY from Gameshark's official site. 4, If a code sounds suspicious, DON'T USE IT! Only the suspicious codes can destroy your game. 5, the code creator only works sometimes. Also, the codes made by the code creator can mess up your game. Overall, Gameshark is a good buy, but remember my advice!
