I suck at making homebrews (in computer programming in general), but I was hoping someone would hear me out and develop some kind of program that allows you to see all you friend codes without having to select each game one by one. In fact, it doesn't even have to be on the DS, maybe you can use it on the computer when you have all the game files you need accessible. I don't know where Friend Codes are stored so this might not work, but I'm pretty sure it's accessible through .SAV file. To me it sounds easy enough to make, but who am I to judge. Anyone think it'd be a good idea?
