gameshark's a cd, u put it in the console. what happens next, i don't know. i think it detects all the cheats

First of all, buy the Game Shark CD, then comes the time for finding info about it. Basically most gamesharks have a certain number of games and cheats for them that you can enable, with CD's I think that once you choose your cheat, it says "Please insert the game CD" or somehting along those lines and when you do you start up your normal game, however it will have cheats like the kind you cannot unlock on your own.
