you can trade with any Pokemon Diamond / Pearl of any region... Mystery Gift with Pokemon Ranger. and you can PalPark only with games of the same region (e.g., JP Pearl w/ JP Ruby or EU Diamond w/ EU FireRed)Read up on it here, MaDDawg: http://forums.nintendo.com/nintendo/board/...essage.id=14254
Sorry for not checking Google before asking, but what games can you trade with? Because the game won't be coming out in Europe for at least 1 month so I was planning to play some of the old ones and catch a lot of Pokémon there
