Master Code

The Master Code (m) is required in order for any other codes to work. Each game has it's own Master Code, including different versions and regions.

For each new game title you add to your Action Replay game list, you have to input a Master Code. After adding a new game title, it will bring up a code name input field as if adding a new code. Type (m) as the name, and continue to input the code as you would any other.

Once complete, the code will appear in green on the code list, and will always be activated. If you fail to input the Master Code at that time, then it wont appear in green and you'll have to check it like a normal code to use it. If this does occur, then you should delete the game title from the game list, and try again.
