Hi, I'm in France and I have an american 3DS, so I buy only american games. I want to buy an american Mario Kart 7, but I want to know if local wifi multiplayer (with each gamers having one cart) will work between the PAL game and the USA game ? (in order to play with friends here in France) Until now, there seems to be no specific rules... Streetpass, Pokedex 3D, Street fighter 4 are working great. But Starfox 64 3D, Dead or alive dimensions, Zelda four sword 25th anniversary are not working (we can't find each other when trying to play together). So if anyone has tried this configuration, please tell me if this works or not ? Thanks !
