ROM Hack Question Extract save from NAND backup

[hippy dave]

if im getting these errors is it because i'm using an old version?

Failed to match key eticket_rsa_kek_source

They're just warnings you don't need to worry about, it happens when the key files has extra keys that hactool doesn't recognise or need. So this doesn't tell you anything about the success of what you're trying to do, if it didn't work then the problem is elsewhere.

I've looked in two different emuNAND's User partition and the save folder is empty in both. only the system partition save folder has any files. Is this because my saves are being saved to the external SD vs the emuNAND? My system won't boot off the emuNAND anymore after trying to manually update the firmware with ChoiDujour, so I was hoping to extract the saves and inject them back into an older different emuNAND that I on another SD card.

I get the following error when extracting with the latest version of hactoolnet
ERROR: ResultFsJournalIntegritySaveDataControlAreaVerificationFailed <2002-4315>: Savedata header is not valid.
hactoolnet.exe crashed
Is there any way to solve this?

Not sure about the error, but maybe NXNandManager will help Get you what you need Out of :USER/saves

I made a tool.

1.mount user data from nand
2.copy all files from save directory to tool/save directory
3.run.bat
4.you can find gamesave in the out directory

Possibly. Take a look here and see if you can find your saves directly where the Switch saves them. If they are not here, no other tool will be able to find them either.
