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!

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 unsused 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?

    yall im torn... ive been hacking away at tales of phantasia GBA (the USA version) and have so many documents of reverse engineering i've done
  • TwoSpikedHands @ TwoSpikedHands:
    I just found out that the EU version is better in literally every way, better sound quality, better lighting, and there's even a patch someone made to make the text look nicer
  • TwoSpikedHands @ TwoSpikedHands:
    Do I restart now using what i've learned on the EU version since it's a better overall experience? or do I continue with the US version since that is what ive been using, and if someone decides to play my hack, it would most likely be that version?
  • Sicklyboy @ Sicklyboy:
    @TwoSpikedHands, I'll preface this with the fact that I know nothing about the game, but, I think it depends on what your goals are. Are you trying to make a definitive version of the game? You may want to refocus your efforts on the EU version then. Or, are you trying to make a better US version? In which case, the only way to make a better US version is to keep on plugging away at that one ;)
  • Sicklyboy @ Sicklyboy:
    I'm not familiar with the technicalities of the differences between the two versions, but I'm wondering if at least some of those differences are things that you could port over to the US version in your patch without having to include copyrighted assets from the EU version
  • TwoSpikedHands @ TwoSpikedHands:
    @Sicklyboy I am wanting to fully change the game and bend it to my will lol. I would like to eventually have the ability to add more characters, enemies, even have a completely different story if i wanted. I already have the ability to change the tilemaps in the US version, so I can basically make my own map and warp to it in game - so I'm pretty far into it!
  • TwoSpikedHands @ TwoSpikedHands:
    I really would like to make a hack that I would enjoy playing, and maybe other people would too. swapping to the EU version would also mean my US friends could not legally play it
  • TwoSpikedHands @ TwoSpikedHands:
    I am definitely considering porting over some of the EU features without using the actual ROM itself, tbh that would probably be the best way to go about it... but i'm sad that the voice acting is so.... not good on the US version. May not be a way around that though
  • TwoSpikedHands @ TwoSpikedHands:
    I appreciate the insight!
  • The Real Jdbye @ The Real Jdbye:
    @TwoSpikedHands just switch, all the knowledge you learned still applies and most of the code and assets should be the same anyway
  • The Real Jdbye @ The Real Jdbye:
    and realistically they wouldn't

    be able to play it legally anyway since they need a ROM and they probably don't have the means to dump it themselves
  • The Real Jdbye @ The Real Jdbye:
    why the shit does the shitbox randomly insert newlines in my messages
  • Veho @ Veho:
    It does that when I edit a post.
  • Veho @ Veho:
    It inserts a newline in a random spot.

    never had that i don't think

    do y'all think having an sd card that has a write speed of 700kb/s is a bad idea?
    trying to restore emunand rn but it's taking ages... (also when I finished the first time hekate decided to delete all my fucking files :wacko:)
  • The Real Jdbye @ The Real Jdbye:
    @Karma177 that sd card is 100% faulty so yes, its a bad idea
  • The Real Jdbye @ The Real Jdbye:
    even the slowest non-sdhc sd cards are a few MB/s
  • Karma177 @ Karma177:
    @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really think it's faulty (pasted 40/50gb+ folders and no write errors)
    Karma177 @ Karma177: @The Real Jdbye it hasn't given me any error trying to write things on it so I don't really...
