Hacking Question about region free gateway

[Herobroski]

If I download x, y, or any other online 3ds rom, could I still play wifi battles with my friends?
When I download ANY 3ds rom that is not in my select country (example: Im from U.S. but choose EU), does the rom prevent me from using online features in my country? Like If I got Pokémon X as a EU 3ds rom, would Gateway allow online features? I know it will at least let me play the game due to region free but will it interfere online features?

Im basically curious if the region of a 3ds rom that I download IN ANY WAY might interfere with my game, Nintendo events, or online capabilities, etc.

No flashcart has online multiplayer enabled. Only local wireless play is available. Games that have DLC but no other online capabilities; like Fire Emblem, Professor Layton, and Conception II; will be able to access the eshop to buy their DLC, provided that you're using the most recent system update via emuNAND. Games with DLC and online capabilities (Bravely Default) will not be able to access their eShop at all.

If got an EU 3ds pokemon x rom, could I still play locally with my friends while I live in the US?

I think you can. It doesn't matter whether two consoles connecting locally are from the same region.

It appears to be dependant on the game, and for pokemon (Japan/US at least) it does work.
