How do use a dsi action replay on a dsi?

okay so first you must go onto that game when youre on your action replay. then you press add new code. Then simply type in the code letter by letter and if it doesnt all fit the code will not work but copy it one by one and then press okay and name the code for what the cheat does. Then just check it or whatever and start the game up and it works. The code should say you need to press select or something once you are on your game for it to work as well fyi. hope i helped
