    Hello,

    I have a 4.5 sysNAND with the NAND HW Mod and I'm doing some tests with the DGPacks, the new exploit and 7.X encryption keys with games.

    So what I did was backup everything (sysNAND 4.5, enuNAND 4.5) and then I updated my sysNAND to 7.2 using a Pokemon OR original cart. After that I recriated my enuNAND based on the 7.2 and updated it online to 9.4. After all my tests are done, one question remained:

    Is it possible to migrate my 4.5 emuNAND "streetpass tags data" and "mii plaza data" to my 7.2 new emuNAND?

    I read somewhere a guy doing a "system transfer" from/to the same console.

    Could I flash my emuNAND v9.4 (based on 4.5) to sysNAND and then do a sys transfer to my SD card emuNAND 9.4 based on 7.2?

    Cheers!

    If you format emunand using GW it should keep your Streetpass (since it recreates your nand), the save data for streetpass (excluding the dlc games) seems to be saved in the NAND so...

    Hey, thx for the reply!
    My question is about something else.

    I've been using my emuNAND 9.4 (based on my sysNAND 4.5) for quite some time, therefore I have lots of streetpass data, mii plaza and other stuff in it.
    This emuNAND was based on sysNAND 4.5, so it does not "decrypt" 7.x new encryption based saves. So what I did was take my 4.5, update it to 7.2 and created A NEW emuNAND based on this 7.2 sysNAND. Of course it does not have all of my data because they are in another emuNAND (not sysNAND).

    So my question is: is it possible to migrate my data from my previous emuNAND 9.4 (based on sysNAND 4.5) to my emuNAND 9.4 (based on sysNAND 7.2) using the same console?

    Thanks!

    Your new emunand should have the same link with your other 9.4 emunand, if you can find the place where is stored the streetpass data, you just have to place it in your new emunand.

    If can be done, it should be done with emunandtool, dunno how but.

    Well, I don't think emunand tool will help here.
    It will have to be done either by sys transfer (somehow) or via hex editing... I don't know

    Any other clues?

    If not, I'll have to return to my old 9.4 emuNAND (based on 4.5)... I'm not losing all of my streetpass tags and mii plaza data. :)

    As far as I know, Your old Emunand should be able to decrypt >6.X saves as long as your actual sysNand is >6.0, even if the Emunand was made while Sysnand was 4.5.

    Anyways, try using SaveDataFiler and extract the HMEE file (which is the ExtData of Streetpass Mii plaza, probably that's where the streetpass tags are saved) from your old Emunand and inject it back to your new one (remember to delete the HMEE on the new one before injecting it). Of course, backup everything first before trying that o:

    I tried that to no effect, but others are welcome to try.

    How exactly did you try this? What did you extract?

    I've tried using savedatafiler to extract all of my extdata (210, 217, 218, 219, 21b) from my emuNAND 9.4 based on 4.5 and importing them into my 9.4 emuNAND based on 7.2 but yet the streetpass does not work.

    I'm considering a "more desperate" option :P

    What if about I inject my emunand 9.4 (that contain all of my data) to my sysNAND (yeah, I have NAND hardwaremod) and do a sys transfer to another 3DS, wait 7 days and do another sys transfer to my original console now with a emuNAND 9.4 based on sysNAND 7.2 injected to sysNAND. Yeah. A little complicated, but you got it.

    Bottom line is I will be using a second console to "hold" my data transferred so I can transfer them back to my original console with the correct emuNAND 9.4 base on version 7.2 (with the new 7.x+ keys)

    Could this be achieved? Will it work?

    Cheers!

    I tried something similar. I needed to transfer from a machine with 9.2 Sysnand to a machine with 4.1 Sysnand (both with 9.4 Emunand). I extracted the extdata, copied it onto the other machine, and loaded it. This did nothing whatsoever. There's a 218 under "User" but it is listed as broken and cannot be extracted. Also, http://3dbrew.org/wiki/System_SaveData claims there is a system save file and I can't figure out how to extract that (unless it's the "broken" user file).

    Yeah!
    I guess that's a no go then...

    I still wonder what about my last suggestion? Using a second unit as a temporary transfer.

    if you can read and write to nand then it is easy to extract it from one nand and write it back to another :)
    it is very possible to do this, i have a launcher.dat that would be perfect for it, but i don't want to compile a new version for whatever file someone wants to dump/inject/swap etc.
    so ideally i want to include a keyboard or something in the app so you can type what file you want, but that is tricky :(

    So "easy to extract it" means "write your own launcher.dat which does it? I wouldn't consider that easy. And certainly SaveDataFiler isn't enough to do it.

    I'm not on 4.5 but I imagine this process will still do the trick:

    1. Create emuNAND partition with linked sysNAND
    2. Remove SD card and copy contents to PC
    3. Create emuNAND backup with emuNAND tool
    4. Insert SD Card
    5. Format sysNAND
    6. Format emuNAND
    7. Remove SD Card
    8. Copy backup files back on
    9. Copy emuNAND backup onto SD card
    10. Insert SD Card
    11. Boot to GW Mode
    12. System Update from 4.5 to 9.4 in emuNAND
    13. Enjoy

    All of my previous street tags, miiplaza, etc. still exists. I don't see why it wouldn't be the same here. I am having an issue with my homepass now though which is discouraging.

    Hello! Well, I'm not sure the scenario is the same.
    Let me explain what I have so you tell me if this would work or not

    This console is a Mario Kart 7 bundle I bought in 2013, therefore it came with 4.2 (or 4.3, I don't remember correctly). Back then only 4.1 to 4.5 consoles were exploitable.
    Then came the new 7.X+ encryption keys and saves created later do not work in earlier FWs, so if I have a friend with an original cart (like Pokenon ORAS) trying to play it on my emuNAND 9.4 (based on version 4.5) it only tells me the save is corrupted.

    Now fast forward to Gateway 3.0 ULTRA release. This GW FW enables us to use FW up to 9.2, as we all now. So what i want is to:

    1) Backup my current set up (sysNAND 4.5, SD card emuNAND 9.4 - based on version 4.5 - and SD cart files) and save it somewhere else
    2) Update my sysNAND to 7.2 (using a Pokemon OR cart)
    3) Format emuNAND again in my SD card (this time this NEW emuNAND will be based on 7.2 which can decrypt the new saves and stuff)
    4) Boot into my emuNAND and update it to 9.4 online
    *** Now is the tricky part ***
    5) Somehow export my old emuNAND 9.4 data (based on version 4.5) and inject into the new emuNAND 9.4 (based on version 7.2)

    This is a TOTALLY new emuNAND, therefore it's "blank". It doesn't contain any data, so I have to create another Mii, set up streetpass and everything else. This is exactly what I DO NOT WANT. :)
    I want a way to reuse all of my data in a new emuNAND (still for the same console).

    Got it?

    Thanks for the help though!

    I gotcha now. Yeah that I'm not too sure about. Well with the downgrade option from GW you'll have more than enough options to test, just make sure your backups are in order! I would be curious if you could inject your old emunand backup to your new emunand. I'm not afraid to try that stuff because I know it won't brick the device, just need to overwrite with your backups which can be time consuming. I'd just give it a try and see what happens.

    mvmiranda - why don't you only update sysnand to 7.2, and leave everything else the same?

    Well, honestly I'd like to use the old DS profile exploit... :creep:
    What I really wanted to have is to continue using my 4.5 sysNAND while using a emuNAND 9.4 based on 7.2.

    Now that's something I'm considering downgrading for! I didn't want to because of the save game issue, and being able to play carts on sysNAND without GW mode, but now that you mention it that would be really awesome! No more website hack needed and it can all be local.

    how about performing system transfer from emunand to emunand? would system transfer include the mii plaza streetpass stuff?
