I have recently purchased a Mad Catz Game Shark SP I would like to know..

First connect to your ruby
Then turn on game shark and you choose add code
*note* must have game shark codes to put in the code bank.
You can find those here on supercheats.

Then when codes are entered choose the part that says play game with codes.
Note* gamesharks can mess up your game big time!!!!!!!!!!!!!!!!!!!!!!

You can either connect to the internet to the official gameshark website through a USB cable or put in each cheat manually( when you look at gameshark codes there will be a series of numbers next to it and type those numbers in your game shark). If you don't already have the name of the game you want cheats for inside your gameshark, then on the gameshark choose add new game and put in the title of the game. If you want to put a new code in the choose add new code , pick the game you want to add the game to and then input the code numbers.

Try lookng it up on the internet,to see what you can learn about it.

You can connect it to your computer using the proper cords. Then on the computer add codes to the Game Shark to make them use able on the game.
