    NEW -

    A nice video showing off a JPN console region changed to all regions! (I had to get some help to build a launcher.dat for iQue)
    The method is by me but I gave it to tanglangxia at duowan and he tested it lots, and had some fun! (He made the video, it's his)

    --------

    Ok, so whilst everyone had a ticket for the hype train... here is a video that is showing my JPN 3DS loading JPN emunand on one sd card, then changing the sd card and loading up a different sd card to an EUR emunand.
    It wasn't so super simple to achieve, and the result is not 100% perfect, but it is good progress!
    I won't share the program I made to do this just yet, because it is not ready for 'public release'. But, it is nice to share progress and things :)

    (I had this yesterday, but I took the video today - it has nothing to do with GW's new launcher, I just updated to it before I took the video, all that is really required is 4.5 and a ds mode flashcart)

    (sorry about the youku link, it's the best i can do with my internet at the moment)

    thanks to enler for sharing some filesystem code with me, without it i would not have been able to have done this!

    --if someone wants to make a mirror of the video on youtube, i would appreciate it!

    Nice work. Should be possible to do with N3DS when we get GW+emunand support too!

    Can you access eShop with EUR emunand and download game updates for EUR roms?

    This is interesting.

    How does the 3DS determine which server to get updates from? Could it be possible to install multiple copies of the eShop, all from different regions, and have access to updates from those regions simultaneously?

    there is one specific value that is used to determine what updates to install. (they are probably on the same 'server', just different files) :)

    A value on the system/eShop? Might see some homebrew that allows that to be switched similar to the Wii one day :P

    this is great do you think it will one day be able to permanently change the sysnand?
    say if i had the eevee 3ds xl could it be turned into a USA unit and play US games and use the eshop just like a retail U console?
    i know its not ready yet and you used emunand not sysnand, but in the future maybe?
    i'm not interested in emunand or piracy just playing american retail games on japanese consoles.
    sorry for the stupid question and the long post.

    i heard on wii this was easy to do (not much protection), but it is not the case for 3ds!
    yes, that is what i have kind of created, although it is a lot more involved that wii.

    yes, this would work on sysnand, just the same as emunand :)

    If it's possible on emunand it should also be possible on sysnand. You're just taking a risk.

    cearp I'm guessing this is similar to the method that allows old DS flashcarts to work on newer firmwares, just .cia replacement? What problems and bugs are there at the moment?

    not at all, it's a lot more involved than that! as i said in my updatecdn thread when i made the tool that first let people download system titles and create cias - i installed 5.0 KOR over my 4.5 JAP, but the system was still japanese... so changing the region is not as simple as we would like

    Different Region, different TitleID's. Installing different Region Files would leave the unused untouched and might block further installs > easy brick.

    that isn't a problem at all actually (with regards to blocking updates/bricking etc) :) but yes, the old region files are left behind, i could pinpoint each one down easily enough frmo the title list for each fw vesion, and delete them theoretically, but i'm not sure it will make any difference so i will not worry about that just yet :)
    but yes i tested the whole thing without a nandmod, very risky :) i could have easily have bricked my 3ds if i commented out one line of code, scary stuff :D

    Surely it's safe on emunand?
