[quote name='Yertle']Where do we find our friend code in game, I can't seem to find one. The GTS rocks though, I traded a starly for a Chimchar, good stuff. Though the name is in Japanese, I'll just breed it later whatever[/quote]
When you enter a pokemon center, go down the first stairs to the right to get the wifi link up trading/battling. The woman on the right will give you your friend code.
Local trading can be done at the first pokemon center i think. You go upstairs to the pokemon center union room. Once you enter others can connect to you and they show up in that room. Talk to them for trades options etc.
