How to Manually Add Codes Into Action Replay for the Nintendo DS

By Ashley Poland

The Action Replay for the DS is a hardware cartridge that allows you to download and use cheats for your Nintendo DS games. While the Action Replay comes preloaded with hundreds of cheat codes for most DS games, sometimes you'll need to add codes manually. Codes are available online from many sources, including the website for Codejunkies -- the manufacturer of the Action Replay. You can add codes directly on the DS.

Step 1

Make sure that your Action Replay is upgraded to the most recent firmware; to do so, connect the Action Replay to your computer using the USB cable that came with the device. After upgrading the Code Manager software, click the DS cartridge icon a second time to update the firmware. When completed, disconnect the Action Replay from the computer.

Step 2

Insert the Action Replay into your Nintendo DS and turn on the console. Click the star button icon in the bottom-left corner of the screen.

Step 3

Select your game from the Action Replay game list. If the title you wish to add codes for doesn't appear in the list, select "Add New Game." You will need the Game ID to add the game to the list.

Step 4

Click the pencil icon. Skip past the edit screens for the name and ID of the game if they're already entered, select "Add New Code" and click the pencil icon again. You will be prompted to enter a name for the code. Name it whatever you like and click "Next" when you've entered a name.

Enter the desired codes. You do not need to add spaces or line breaks -- the Action Replay will do this automatically. Click "Next" once you've entered the entire code.
