Anyway to battle against ppl using pokemon diamond rom?

Is there anyway to battle people with using diamond rom O.o or is that not possible.

if you're using a flashcart then yes, just do it as normal.

yep, nothing diferent at all, in the other hand I think you can´t play via nintendo wi-fi connection, you know, on internet

ive used my pokemon roms via nintendo wifi. put them on GTS.have not tried to put them on ranch yet

so,it is possible, mmm... how did you did it?

you can't play wifi using an emulator, however you can play people online using a flashcart because it uses the DS's wifi settings.
