Not necessarily. Only if you want to battle people online.
You go to the bottom floor of the Pokemon centre, HOWEVER you need to have friend codes to actually battle
Via Nintendo Wifi.
wifi/ internet connection
yes you can my friend
Using WiFi you can trade w/ others online.
You can trade, battle, and have voice chats with your friends over Wifi in Pokemon Diamond/Pearl, but to do so you need to know your friends' Friend Codes, and your friends need to know your Friend Code.
yes
You need a wifi router or a Nintendo wifi usb
if you have Pokemon pearl or diamond you can connect 'em up and send legendarys from your ds to Pokemon battle revolution. :)
My code is 4082 5919 5699
First you have to have wifi. If you do than you have to beat the game and go to the fight area. then go to the right for a while than go to the battle tower and chose battle using wifi.
because you need better wifi
No, you need their friend code. UNLESS, you are in the Battle Tower doing a Wifi tournament. That's the only way without friend codes.
Believe in your pokemon... and take the wifi battle tower challenge!
i think it could be any level, because on a ds link battle it doesn't ask so it has to be whatever, 9i've never played on wifi before, so...
Use the wifi connectivity from your ds to your wii and you can battle with the Pokemon from Pokemon pearl, diamond, platinum, heartgold, and soulsilver versions
Yup.
