Hello guys. I have a sister who is moving to the USA in 6-12 months from Europe. Me, my brother and our youngest sister want to get her a 3DS so we can play together for the remaining months she's still here... while she can also use the system in the US to play those games. We're considering importing a US system, but chances are the extra costs will end up being insanely high (basically, it could cost us up to 350 Euros, if not more), unless we happen to be very lucky.
So I'm considering to get her a PAL N3DS XL and removing the region lock. It's not like Nintendo will release anymore significant updates for the system anyway, so she wouldn't be missing out on important updates. Anyway, I can't really find a good way to remove the region lock for later firmware... I'm assuming a new system will come with 11.0.0 firmware or at least after 10.0. Cubic Ninja wouldn't work unless I'd downgrade and I imagine the game's very expensive to get. So is there a way to remove the region lock without that game? Ideally, she'd just insert a game card of any region and would then be able to just play it like a regular 3DS game... but if some external homebrew program is required, it's fine as well.
I can manage to install that menuhax thing and possibly that browserhax thing if it's required, but I'm a little lost in what else I'd need to do to remove the region lock.
