    Hey...

    So, and sorry if it's an stupid question, could we resize our emunand partition?

    I'm missing with the ending sector and size of partition but as they are fixed values in the first 1024 I'd wish to resize my emunand to 15Gb...

    Code:
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01
    01 00 07 FE 7F 9E 02 20 A4 03 FE DF 2B 1A 00 00
    Here's my hex data (256Gb exfat)

    I don't know how sx os recognizes the emunand "partition" but I think that it always looks for the same sectors, so I assume we cannot resize the microsd emunand yet.
    If you want to try, you should first make a backup of all your data and then resize the fat32 (or exfat) partition with GParted or similar software, but I think it wouldn't work

    It is absurdly simpler and easier to use the same method that was used in the early days of emunand in 3ds, use the HDD RAW Copy Tool to create an SD image and then inject into the other (or copy entirely from one to the other directly), after that use the Minitool Partition Wizard (or any other similar program) to resize the partition (if it is in fat32 you should give it to resize directly, if it is exfat you need to copy the visible files from the SD to PC, then "delete" the visible partition and recreate, taking care to create the partition just after where the emunand is) It sounds complicated, but it's quiet, there's a video (it's not mine, I found it on youtube):

    Hey, so I tried doing this on Windows. But after creating the combined emunand.bin file I tried to copy it back, but it always gives me access denied. What can I do about this?

    Hi I successfully migrated from system partition emunand to sd files and then, following this tutorial, to hidden partition emunand and switched to atmosphere. The problem is that the emunand on system partition was of 20GB instead of 32 and now I have a 32GB hidden partition but a 20GB emummc. To not waste space is there something I can do for resizing the emummc? Thank you

    EDIT: in case someone has this problem too I found a little python script (there's also a windows app) which resize the user partition from emunand.bin.

    Code:
     https://gist.github.com/ckurtz22/5748f3f761e0a546675f2720a1e5e486 
    The default user partition size is 0x680000000 bytes and the tool accepts the size in decimal GiB so 26 GiB should be the correct default size. I still haven't tried this but I plan to do it later this day and report.

    EDIT2: I successfully resized the emunand with the python script above. The emunand input file it takes is a concat of boot0, boot1 and all full.xx.bin so without first1024.bin. After resizing is done you can concat first1024.bin with resized emunand and burn to SD as OP.
    Beware that while you will retain your profiles and play statistics all other things will be lost, including saves so make sure you have a verified backup of them first. After booting the new emunand you will notice that your saves seems to be there but you will receive an error trying to start your games. You'll have to remove the saves for the game manually from system settings and, if needed, restore them from a backup and your game will load fine.
