This tutorial will guide you step-by-step on how to put Action Replay Codes onto your DS by using your computer. It is a fairly simple process. You will just need the help of a program called the Action Replay Code Manager. This program will help you manage, delete, add, transfer, and do basically whatever you would like with your codes.

Action Replay Code Manager

You can get this program either 2 ways: the disc that came with your Action Replay DS or a safe download from Codejunkies (the official AR Site).

Here are the links to download from the Official Codejunkies Site. These files are 100% safe. They are the same files that you get off your disc when you first purchase the Action Replay DS. If you are still unsure about downloading, then it will not be possible to add codes:

American Version: http://us.codejunkies.com/nds_actionreplay/SetupUS1_05.exe
European Version: http://us.codejunkies.com/nds_actionreplay/SetupEU1_05.exe

Now install the program and we'll be on your way. When you open the program, you should get a "Waiting for DS" screen. Now connect your DS with your Action Replay in Update Mode. If nothing appears, then view this tutorial:

Next hit the "Software Upgrade" button in the top right corner. This will insure that you have the latest version of the software, which carries the capibilities needed for this feature.

Under the "Nintendo DS" category, browse to the game you would like to add codes for. Now simple right click on the game and hit "Add code". From there it will prompt you with a title and code text field. Fill them out and hit "Ok". You're good to go!
