1 go to the pokemon center
2 go down stairs
3 talk to the lady to get your friend code online
4 give someone you game name and you friend code and then the other person will give you the name and friend code
3 when you register their friend code and name in the palpad you just talk to teh lady again downstairs and it will take you to wifi and then you start the battle when hes online
I have Pokemon Diamond, but I'm not that far in it so far as I only have two badges! Do you need to have all eight badges and visit Pal Park for an online battle? Not sure how the online battle works???
