Hi! About your request, Nintendo disabled most of the Wifi services for DS games, that means there is no way to trade pokemons online for the following games: Pokemon Diamond/Pearl/Platinum/Heart-Gold/Soul-Silver/Black1-2/White1-2, using the conventional trading system, only trading pokemons into .pkm files or .sav files. If you trade using .sav files you will need to have 2 DS systems, a flashcard and a cartridge; if you trade using .pkm files, I have no clue how can you send the pokemon to your cartridge.
