I just got a Action Replay (AR) 3.0 and it works for the games that were on it to begin with, but i need help putting codes in. I've noticed that the preloaded games have a (m) code, which i assume stands for master code. I tried putting master codes i found on the internet for Pokemon Emerald, and none seem to work. It won't even let me check the boxes for it. Please help me if you can and if you can give a link to a place with lots of Action Replay codes that would work, Please do.. That's about it. Thanks
