and where do I find my number code (Nintendo should really stop using number codes. I prefer Medal of Honor's way of adding friends. All you do is write their name and send a friend invite. If you have it I'm Doctor Doom there too.)
"A Lucario", hang on while i get FC
K, go to Wi-Fi main menu (find game, private match, etc) go to private match and select it. Next, go to friends. Choose add friend and enter "338365360282". If you need name, do A Lucario
