How to Enter and Use Cheat Codes on an Action Replay Device
You do not "register" codes like an account. Instead, you **input** them directly into the Action Replay hardware/software interface. Here is the standard workflow:
Step-by-Step Guide
Obtain the Correct Codes: Find codes specific to your Game Title, Region (USA/EUR/JPN), and Game Version/Revision (often printed on the cartridge label). Reliable sources: GameFAQs, CodeJunkies, MaxCheats.
Insert Hardware: Place the Action Replay cartridge/disc into your console (DS, GameCube, PS2, etc.) and boot it up.
Access Code Manager: Navigate to the "Add New Code" or "Cheat Editor" menu on the Action Replay main screen.
Create a New Cheat: Enter a Name (e.g., "Infinite Health") and the Code String (usually multiple lines of hexadecimal, e.g., 1206F5E0 000003E7).
Enable Master Code (Critical): Many games require a "Master Code" or "(M) Code" to be added and turned **ON** first. Without this, other codes will not work.
Activate & Start Game: Check the box next to your desired cheats, select "Start Game" (or "Launch Game" / "Play with Cheats"), and swap the disc/cartridge if prompted (disc-based systems).
Important Precautions
Save Before Cheating: Codes can freeze the game or corrupt save files. Save your progress before activating risky codes.
One at a Time: Enable codes one by one to identify which causes instability.
Hardware Limits: Older Action Replay devices have a limit on how many lines of code they can hold simultaneously.
