yes, but i bricked my emunand, i simply reversed the change and unbricked it, but if i was accidentally writing to sysnand when i thought i was writing to emunand, it would have been 'game over' for me :D

Dang haha. I assume you've got a dump of your clean 4.5 sysnand, just so that a hard mod is available in worst case scenario?

Standing to what they said on 3dsdev months ago, it is possible but Nintendo has a database of console-specific information (serials, or something else, I don't remember well) that gets checked server-side for being the correct region when you go online, if it doesn't match the correct region you can't use Nintendo online services at all. They also said that spoofing random serials is a no-go. So you need a console from the other region to copy the stuff from, and it makes the region-changing kind of unuseful.

So if we had, say, a NA 3DS and a JAP or EUR N3DS we could spoof that serial information and do it that way?

If they already store information on all serials and what region 3DS belongs to me, it wouldn't surprise me if they also stored whether said 3DS was a N3DS or not. That's just a random guess though, someone else will have to confirm that.

Considering that two consoles connecting with the same information will very likely lead to the banhammer...

true, it's probably a risk (which i didn't think of, so thanks for bringing it to my attention!) - but from how they usually are, nintendo doesn't seem so strict. we will see anyway :)
i won't be complaining, the amount i have pirated i probably deserve to be banned lol (if nintendo are reading this, i have never pirated in my life, that was a joke)

Let me get this straight. I can have European firmware on my Japanese 3ds? Update the emu nand with further European firmware if update is available and update European game updates through eshop on the Japanese 3ds?
well hopefully in the future, in reality no i have not gotten that far yet, and i might not be able to get further, at least with the resources i have (i'm not going to buy more/'fresh' 3ds consoles to test etc) you can have eur firmware yes, we could even write it to sysnand i'm sure, and make it only play eur games instead of jpn. --- but at the moment i personally have not got eshop to work yet.

some people might think this is worthless without eshop support, and well, it's not worthless since i haven't even released anything - but the guys at duowan said it would be very useful for some of them, some chinese games do not play well on japanese fw (or something like that, some combination etc) - the font is all wrong etc.
maybe it might be fixable by installing the needed font system titles, maybe it is not that easy.
at a worst case scenario, this would fix it :)

Ah I see.
Well I guess I will stick to CIA updates for different region for now.

You see I have a Japanese 3ds with capture card and a European 3ds.
I play European games on both, but when updates come out I have to install update CIA on the Japanese version -.-
The whole python thing is a hassle man.

Could you re - edit your tutorial on how to dump eshop stuff?

nice! So this means that these games that need the console in same region to work 100% (like, I heard that we can't play taiko no tatsujin multiplayer/online just with regionfree) would work?
and it's possible to enter their eshop, buy/get stuff and back with then there when chaging region? o3o

What happens with the profile? I mean you see my FC there, but I change my name to japanese caracters and back to US emunand?

yes, when i changed to eur, my profile name was still my name with japanese characters. although if you wanted to just change the name you could probably use one of the sdk tools maybe? or i'm sure someone could make a launcher.dat to edit the file in nand where the profile name is (i saw the file somewhere...) :)

python is tricky for you? how so? i have no experience with it on windows. on mac it is a BREEZE!

I heard that the Aikatsu! games are unplayable if you don't have a JP console (something to do with the keyboard), so that'd be awesome! Do you by chance know of any other games that are still region locked?
sorry for going kinda off topic

maybe diagasso band bros p i heard? maybe

I have a feeling that tutorial is only useful on the blue card right? New GW users I don't think can backup eShop CIAs...
