An action replay has to be in the DS, gameboy, whatever before it is turned on. Once the device is turned on the action replay "game" will start up. At this point it wil tell you to take the action replay out and replace it with the game. From there you can select the cheats you want to use in the game and start the game with the active cheats. Some cheats like walk through walls may require you to hold a button such as R whilst walking into a wall.
When you use an action replay 99% of the time your save file will be corrupted and you will have to start the game over.
If it doesn't have a slot on the top of it then you probably bought Action Replay DS, not Action Replay DSi. To use Action Replay DS you type in the code you want, check-mark the codes you want to use, then pop out your Action Replay DS ( while the DS in on!) and pop in the game you have the codes on for, then press start game. If you have Action Replay DS then when you pop out your Action Replay it won't freeze, so you can still start up your game with the codes.
if you mean how to use it you put the game in it and then you start playing
Don't use two action replays on one game it will freeze it or if pass it all and then start using it the game will be unfamiliar with the action replay so it will erase the game, or if you cheat to much then it will freeze and there will be a possibility that you my never use you action replay on your game EVER AGAIN.
Just put Action replay into your DS's Game slot and turn it on then when the Action replay screen comes up then take out Action replay and replace it with your game card then press the star ,select the codes you want and press start

Put the game cartridge in the action replay.
