Pokemon Pearl and diamond

Hi
How do you trade between Pokemon Pearl and Pokemon Diamond using the "no$gba" emulator??

You can't at the moment. iDeaS might be able to though.

if i get iDeas then will the save file of my current pokemon pearl and diamond be there?or will i need to start over?

Mostly likely have to start over. That being said, iDeaS can't link or trade at the moment.

i think that if you have a plugin for ideas, you might be able to use wifi and trade, but i'm not sure. cloudboy used to like ideas a lot, ask him about it. if someone knows, it's him.

Easy Way: Search Google or Yahoo about Capturing all Pokemon codes if you can't trade in a computer you know. Also search for event pokemon codes if you can't get the mystery gift.
And the no$gba has an action replay code by pressing F2 or Click Utility. Copy and Paste the code and there.Always remember the slogan: Gonna Catch'em All!!
