I have a question. When my Japanese Platinum comes. Will I be able to trade with my Europe Pokemon Diamond and Pearl games?
Not immidietly but you should be as long as you have two DSes. If DS to DS doesnt work, try exchangin FCes and then logging both on to wifi. Idk when you can start trading, youll probably be able to when you get badge #1. I am waiting for my copy to come in aswell.
