Well, it's acually just called an AR. The AR stands for Action Replay. Im not sure why it's called that but it's a device that hacks games up. there is an AR for the GameBoy Advance, GameBoy Advance SP, and the Nintendo DS. Most people although use it on Pokemon Emerald. What you do is put the AR in the slot where you put your game. The AR has it's own slot which now you put the game in. After that, search a code on the internet. Once you've got one you like, type it in your AR. When your finished putting all the codes, turn off you console and take out the AR. Then put your game in the slot like you normally would and turn it on again. Your game should work fine but with the hacks in them. For Example: If you put a code for a Pokemon in Pokemon emerald, when you play it, it will have that Pokemon in it.
