The reports I have seen are the first batch of EU N3DS are 9.0 so yes Gateway shoukd work with them if and when gateway releases support for them. No guarantees. Who knows when higher firmwares will start appearing.Welp, my friend has 9.4 too, dang. And since your saying
no nand sharing, no gateway on 3ds for us then...
But, another question (I hope I'm not bothering you)... My friend has told me
that the new eur 3ds comes with firmware 9.0 (from his sources, if it's not fake),
so, as you said, the gateway should work, right?
EDIT: Just a stupid question: It is possible to transfer data between 3ds-3ds/N3ds without
having to update it or what?
I beleive there are ways of transfering data without updating, but I can't help you with that. Not something I follow closely. There are lots of threads on the subject so you will have to start doing your research.
Sky3DS is an option for you as well.
