Dealing with NAND/ EMUNAND safely
YOU HAVE BEEN WARNED
This tutorial will give you useful information on how to deal with NAND/ EMUNAND safely. 99% be safe to follow this tutorial but bear in mind that there is always at least a risk to brick your Switch.
> Make a backup/ copy of NAND and/or EMUNAND before doing anything.
YOU'RE AT YOUR OWN RISK
I TAKE NO RESPONSIBILITY FOR ANY DAMAGES
First thing first, SX's emunand is extremely safe to be bricked by purpose. It creates a full nand backup of the Switch including boot0/1 and all partitions. If you have a working emunand, there is probably no need to backup sysnand as it will be the same. In the event of accidentally bricking sysnand/ emunand, importing all partitions from emunand to sysnand will definitely work and vise versa.
SX 2.3 supports separated Nintendo folder as Emutendo for emunand. Linked the two nands on the same possible firmware is recommended.

HACDISKMOUNT SYSNAND
HACDISKMOUNT EMUNAND
THINGS CAN DEAL WITH
Mount SYSTEM using HacDiskMount
MANUALLY BACKUP SAVEGAME DATA FROM USER
Mount USER using HacDiskMount
This tutorial is for you guys to take a note in case you will need to deal with in the future. I will keep updating this topic when I knew something else.
Enjoy while it lasts.

- PRODINFO and PRODINFOF are identical compare to the ones of your Switch on every firmware versions.
- All BCPKG2 partitions are the same from other devices on the same firmware versions.
- Game savedata is stored in USER partition under /save/*.*

THINGS CAN DEAL WITH
Mount SYSTEM using HacDiskMount
MANUALLY BACKUP SAVEGAME DATA FROM USER
Mount USER using HacDiskMount
On emunand, files are splitted into full.0x.bin
> User command line to merge them in
> copy /b full.00.bin+full.01.bin+full.02.bin+.... full.0x.bin full.nand.bin
Open the nand file using HacDiskMount and mount USER following with Biskey3
> access save folder
> Backup all files to a folder
> Run extract_nand_gamesave run.bat with all your savedata backup to /save/
> User command line to merge them in
> copy /b full.00.bin+full.01.bin+full.02.bin+.... full.0x.bin full.nand.bin
Open the nand file using HacDiskMount and mount USER following with Biskey3
