multiplayer

can we play muptiplayer games with pirate roms on nintendo wi fi ? ???

Yes. If your flashcart supports wifi correctly. WiFi will not work on Emulators, none of the DS emulators support online multiplay.Some carts require arm7 patching to play, and that messes up the WiFi capabilities of the game most of the time. If that happens, then it will not be able to play online correctly.

so it means that they can not block my dstti that way ?

Nope. It can only be blocked by downloading new DSi firmware for now. Correct me if I'm wrong.

I'm not sure what would happen if you tried to play Nintendo WiFi games online before their release date. I know Microsoft can ban Xbox 360s from Xbox Live if they catch you doing that... but I'm not sure what nintendo can do to you about it.But they won't be able to block your flashcart on your system, but maybe your system or IP address from their servers?Maybe someone else knows more.
