I can atleast confirm that it doesn't work on other systems than JP, but if you boot your game on a JP device via regionfree from hbmenu, then it does allow you to get the pokemon.
even if it uses nintendo zone... doesn't that just give you a code?
then you can use it on a EU cart as long as the 3ds is JPN
(boot with regionfree... HANS on a eu/us 3ds doesn't work since it doesn't detect any updates to the software so you can't even get to input the codes cause it'll give you an error saying you need to update)
