[NDS] Wi-Fi & R4iSDHC

Hi,yesterday, I did set up my Wi-Fi for the NDS. All does work great, like browsing, uploading or downloading Highscores for Games (Hoembrew & Ninja Gaiden). Now, I've tried playing online in this Games: Metroid Prime Hunters, COD MW Mobilized, Mario Kart DS, Animal Crossing and none of them seems to work, I can't find anybody?! Is it just there are no People playing at this time? :DThanks, now I'll goto school :-p

Or is it necessary that I have FriendCodes?

Yes indeed if I'm correct you'll find none
without the friendscodes

Replying to #2

Wrong.
There are some games that allow playing on Random.
You do not require Friend Codes for those.
I used to play Metroid Prime : Hunters on random all the time.

okay it is good to learn something like this
I did not know it for surebut then I'll apologize for my wrong conclusion
