Query: Gameshark PS2

I did not like the gameshark for PS2. It was ruining my system. It always jammed my games, and even caused my system to overheat! I found something much better. It is the Codebreaker for PS2. It doesn't use the same method as the Gameshark. It stores the codes on your memory card that you can save games to, so you can use it on saved games. It also does not take up much room to save new codes on your PS2 memory card. I have entered over 150+ codes and it takes up 150kb's which everyone knows thats not much. So if you are looking for a cheat device, buy the Codebreaker.
