    What? Do you want to dump a save file (you can use SVDT),
    or decrypt a 3ds game on the PC (you can't do this, but you can download an already decrypted game on the Internet)
    ?

    I have a .sav file on my PC from a .cia game. It is encrypted.

    I want to decrypt it and send it to my new emunand using SVDT

    but

    The emunand is broken, I can access that save file on a 3ds anymore. I only have it on my PC.

    I have to .sav -> decrypt on PC -> sd card -> SVDT -> resotre to working emunanz
    My only option man

    U know what I'm mean?

    Just try to preform a movable.sed transfer, then use the same Nintendo 3DS folder. Someone else can give you details, since I'm at school.

    I think it's just: dump the movable.sed of the emunand using decrypt9 (Emunand option -> System file dump -> movable.sed).
    Then, inject a backup of the sysnand into the emunand (but... do a backup of the bricked emunand before with decrypt9 just in case XD ),
    and inject on the emunand the movable.sed file.
    And.... That's all! But yeah, if you're not sure of what you do, just wait for a better tutorial from @LinkSoraZelda (I'm counting on you, i'm too lazy :P)

    edit: err..... I don't know if it's necessary, but maybe you have to dump and inject the following files: ticket.db, title.db, nnidsave.bin (if bricked emunand linked with a NNID), and configsave.bin...

    edit n°2: yeah, wait for a better tutorial....

    Hey, I'm back.

    Before you start anything, if you bricked your emuNAND by installing a botched system title, like a bad HOME Menu, you can replace it with your working NAND and you should be up and running with the emuNAND. For a bad home menu, you can find and replace this on American consoles by going to CTRNAND > title > 00040030 > 00008f02. If you need another region, just say.

    By the way, this is a transfer, so it'll overwrite your current NAND data.
    --------
    To do a movable.sed transfer, just make a backup of your current used NAND.

    Mount your emuNAND on your PC. Navigate to the dbs folder and everything inside it. Make a /dbs folder on your SD Card and put all the files on it.

    Then, navigate to the private folder. Copy movable.sed to a /private folder on your SD Card.

    After this, launch GodMode9. Go to your SD Card and highlight the dbs and private folders with the L button (they both should be in yellow) then press Y to copy.

    If you're using emuNAND currently, go to emuNAND CTRNAND.
    If sysNAND, go to sysNAND CTRNAND.

    Do not go into any folders. Press Y to paste, and unlock NAND writing. It should ask to overwrite folders, press Yes.

    Then reboot. Take your SD out and put the old Nintendo 3DS folder with your saves on it. When you insert the SD into your 3DS, everything should be back.
