Basically, it's like this cheat system developed by Codejunkies, the premier provider of cheat devices. If you have, say San Andreas, there are cheats like, infinite health, armor, money and loads of other cool cheats. You don't even need to press any buttons, just tick the cheats that you like and start up the game. I have two, one for PSP and the other for my PS2. I want to get one for my PS3 soon, but I dunno.
