NxNandManager VS NSC_BUILDER

I believe https://github.com/eliboa/NxNandManager might work. But if your nand is corrupted, there might not be a way to get those files.

You could try to extract the saves from the emunand (if its not corrupted yet). You can use nxnandmanager tool (read their github on how to) OR follow this guide

Hmmmm. Take a look at this. It might be more useful than me.

From there download NxNandManager here https://github.com/eliboa/NxNandManager

Not automatically, no. You'd have to use something like JKSV on sysNAND CFW to export the saves and import them into emuNAND. Alternatively you can use NxNandManager, which is more complicated.

You should be able to, yes. The NxNandManager tool by eliboa has a feature where you can resize the USER partition of the input NAND. You'll need to dump your keyset using Lockpick_RCM so that NxNandManager can interact with the backup.

NxNandManager (https://github.com/eliboa/NxNandManager) and your switch's keys to decrypt save from user partition.

I just use torrents, then verify the files with NSC_Builder. It'll cross check files with official store releases and tell you if it's safe / anything has been modified.

You can use this tool https://github.com/julesontheroad/NSC_BUILDER to merge base game roms with their updates and DLC. It's what I did and works perfectly.

Shouldn’t be a problem. I would use NSC Builder, which you can find Here. Just run either the bat or exe and follow the instructions and you should be good to go. You’re gonna wanna choose the multi pack mode since you’ve got multiple files. You can find the combined file in the Output folder of the NSC directory after you extract it. Lemme know if you run into any issues

How can i do this? Since i tried using NSBC here https://github.com/julesontheroad/NSC_BUILDER

Similarly, I use NSCB to merge DLC and updates into the base game. It's saved me a bit of space too.

Dump it to XCI, pass the XCI file to your PC and use this to convert it to NSP file.
