Action Replay is, in fact, a game cartridge that $24.99. To use it, as I assume you're asking, you must complete the following steps....
1. Insert the Action Replay cartridge and boot up your DS.
2. Wait five or so seconds, and take out your Action Replay game WITHOUT turning off your DS.
3. Insert your DS game (in this case, Pokemon Diamond) and start the game. There will be a star; click on it and put in one of the billions of codes you can find online.
That's it!
All versions of Pokemon Diamond work with Action replay codes. However, your Action Replay may have the incorrect ID for the game (if you imported either the action replay or the game), and you must therefore set the correct ID, and get the correct AR codes.
