ROM Hack HacDiskMount - How to? (Need Help)

[toxn]

I have HacDiskMount, I have dumped my biskeys. I have used hekate to make a nand backup.

My nand backup came in pieces. Is there a way to batch these together so HDM can read the full nand? also, when I remove the .00 so I can load my first nand.bin file, My biskeys aren't working for the upper and lower. What should I be using here?

I am trying to copy a save from my emunand into my sysnand backup in order to restore and have my emunand save on my sysnand.

I cannot find a good guide for how to do this and am hoping someone here can help.

Thank you!

I'm still having trouble understanding exactly how to do this however.

HDM is saying this:
[19:39:45:827047] [info] Trying to read partition table from C:/Users/admin/Desktop/switch backup/sysnand 11-15/rawnand.bin

[19:39:45:833387] [info] Loaded primary GPT, checking secondary from offset 31268535808

[19:39:45:833767]

Not enough bytes reading secondary GPT header from offset 31268535808

[19:39:45:833966] [info] Using primary GPT as backup is bad

Also: My biskeys are now working for everything but USER. Does anyone know if I should edit the saves in system or in user?
When trying to access user with the proper biskey HDM says: Error during test, reached the end of file.
