I got my r4 a couple days ago, and downloaded the newest firmware, but now I have a big problem. You see, I bought the r4 mainly to have multiple Mario Kart DS saves handy at one (Hardcore Time-trialer here...) But you see, I need some special Action Replay codes to slow the game down to 100cc so that I can play at wifi speed to refine my skill there. I thought that you could add the code to the action replay database easily, but it turns out I was wrong. I also need a couple other codes. Finding the codes isn't a problem, but how do I actually put the codes IN THE ACTION REPLAY code database so that I can turn them on or off whenever I want, and make sure that all of the Mario Kart save files have this option? I checked the sticky, but I don't understand if that's the answer I'm looking for or not.
