Ok so I've got a few questions not related to bricking!!! So I own an australian 3ds which is part of the European region. So far I have only Used European 3ds roms. I know it is possible to use the gateway to play US region roms. But if I do will download play work with my brothers 3ds which is also australian? And what about local play requiring 2 cards? Say my brother gets a gateway and we both play the US rom on out australian 3ds's will it work?? Or should I just continue using European roms?? Help anyone and thanks in advance!
