Pokemon Battle Revolution was the first game with Wii and DS connectivity. Surprisingly, the G6DS Real was one of the few carts able to access this connection without the need for a patch. It would make sense, logically, that the M3DS Real, which shares the same firmware, and many similar components, would work just as well. Unfortunately, the M3DS Real was unable to connect to the Wii.
