So, I got a new(actually used, but it's new to me) DS phat from one of my mom's friends so I can transfer Pokemon from Heart-Gold to White. Seeings as I want to trade Pokemon through wi-fi with a different DS other than my DSi I wanted to transfer the friend code data. I heard that you can transfer your data(friend code) from DS to DS, but I'm not really sure how to. Help?
