R4i v. 1.4.1 and trading/battling over WiFi or DS-to-DS communication?

[pokefreak1991_22]

Hey guys, this is my first post and this question is important to me as I am a potential buyer of the R4i v 1.4.1 DS flash cart. If you have a save of Platinum on the R4i, can you run the save file from the R4i and trade/battle using that save file, or would you need a real Platinum DS card? Thanks in advance for your help guys!
