    Hey guys,

    I was looking for a tutorial to transfer a working emuNAND to a new SD card, and only found fragmented tutorials which required following other tutorials to work, or one which used a partition transfer tool rather than EmuNAND tools. So I decided to write up a quick tutorial to detail how I transferred my N3DS 10.4 emuNAND to a new SD card.

    There are two methods for doing this: using EmuNAND tool on a PC to backup/restore the EmuNAND, or using EmuNAND9 on the 3DS to do it. The EmuNAND9 method is more convenient but requires you to have enough space on your SD card for the EmuNAND dump. I have therefore included both methods in this guide. You need to follow part 1 to prepare the new SD card, then either part 2a or part 2b depending on how much space you have on your SD card.

    Precautions
    • Make sysnand and emunand backups before starting
    • Make sure you know how to check whether you are on sysnand or emunand
    • Make sure you think about what you're doing instead of blindly following this guide. If things go wrong, you need to know what you're doing so you don't cause problems

    You will need:
    • 3DS with access to Homebrew and emuNAND already set up
    • Minipasta installed to your old SD card
    • EmuNAND9 installed to your old SD card
    • If your original SD card has less than 2GB of available space, you will also need EmuNAND Tool on your PC

    Part 1: Prepare the new SD card for emuNAND

    Part 1: Prepare the new SD card for emuNAND

    Part 2a: If your old SD card has at least 2GB of available space

    Part 2a: If your old SD card has at least 2GB of available space

    Part 2b: If your old SD card has less than 2GB of available space

    Part 2b: If your old SD card has less than 2GB of available space

    Whichever method you used, after powering your 3DS back on you should be able to boot back into your EmuNAND on the new SD card.

    Comments, questions and corrections are welcome :)

    I was watching for something like that. I'll try as soon as I receive my 2 microSD. (One for the n3DS, the other for the Sky)

    Thank you ;)

    A couple of days ago I did that to tmigrate to a brand new 64GB SDXC. For people getting errors like "Invalid Emunand size" or "Cannot format SD" on emunandtool, you have to Backup the emunand on the old SD and the format it using in both cases the GW launcher. Also the 64GB SDXC needs to be FAT32, primary partition with a 32kb cluster.

    Why I need to open minipasta before going to EmuNAND9? Can I use rxTools instead? Thanks! :)

    Well I have a problem trying to start HBL from RxTools or Mini Pasta, then I've started EmuNAND9 without a CFW. It worked as well! :D

    And while EmuNAND9 was open I've selected the option "Dismount SD Card" to switch cards before trying to format!

    Thanks for the tutorial bro!

    Oh, so you don't need CFW to run EmuNAND9? I assumed you would need it! If that's the case I'll try to edit the tutorial.

    Well, I think it does that for you when you choose the option to format the SD card so it shouldn't be necessary to unmount it before selecting the format option.

    You're welcome :)

    personally, i started with dumping the old emunand using emunand9
    while formatting new sd to fat32 format on pc.
    then switched sd cards
    then, while copying all old sd card files to pc, i created emunand partition on the new sd using emunand9
    then copied everything from pc to new sd card (including emunand9's emunand backup file)
    and finally injected the emunand dump.

    you never leave emunand9 on 3ds and its the most time effective way.

    what exactly do you need minipasta for?

    Well yes of course you can do some of the tasks in parallel, but for inexperienced users this can lead to mistakes. The purpose of the tutorial is to put everything step by step in sequence. If some more experienced users want to carry out more than one step at a time to save time then that's up to them.

    I that EmuNAND9 needed CFW.

    Yes! This will result in a complete clone of the SD card data and the emunand.

    You can also use my program to backup the EmuNAND from the old SD card (using the "EmuNAND SD card" drop-down list + the "Extract EmuNAND" button) and then format the EmuNAND on the new SD card with that backup (using the "Format EmuNAND" drop-down list + the "Start format" button).

    This option has been available since v1.0.
