You'll need a game-shark or other cheat code device. The game itself does not have cheat codes. A game-shark (or game-genie, or whatever) replaces the games original programming with the cheat code data. when the game-shark is inserted into the console, the console will jump to the code screen before actually starting the game.
you will need action replay, game shark, and some other hack thingy.
you put it in the game section
you have to download cheats

An AR won't work on GBA, just on Nintendo ds or PSP, depending on which type you get. If you want to put in codes for Sapphire, get a game shark.
you put the game in the game shark and if you have a DS, click on Start GBA Game. If you have a gamboy and/or sp, pop it in and it will take you there.
