but isn't it a DSi enhanced game?
If you're referring to importing Pokemon from your Gen IV games to your Gen V games, any games you use must be the same region as your DSi/3DS if that's what you're using. If you're using a DS, it doesn't matter.so will pokemon BW2 (US) work with my Gen IV and Gen V EUROPEAN GAMES?

hmm
well if i have a pokemon black 2 (US) (flashcart)
and i want to transfer pokemon from pokemon heartgold (EU) (legit)
will it work?
and can i trade and battle with legit BW1 EU?
Yes, as far as I understand it, only the Gen IV game (HeartGold) has to be retail, and HeartGold isn't region-locked.well if i have a pokemon black 2 (US) (flashcart)

will it work?
Trading and battling is completely region-free.and can i trade and battle with legit BW1 EU?
