ROM Hack ninfs - FUSE filesystem Python scripts for Nintendo console files

[Xyphoseos]

if you don't have the nand cid, you can't use this unfortunately. do you not have access to the console? is the essentials backup not in the nand?

I dont have the console with me
Thank you ^^

so I did a lot of code refactoring recently. I managed to add recursive mounting; for example, mounting a CIA/CDN dir will also mount NCCH, and RomFS. so you only need to mount a CIA/CDN dir once, and you can browse the NCCH contents, plus the RomFS. I also separated a bunch of code to a separate module, to reduce duplicate code and hopefully make something more reusable.

Cool!

I can make this to work easily on my manjaro linux but not in windows (OSError: Unable to find libfuse). It looks like WinFsp is missing, but I already have the newest version installed.

//Solved it while I wrote this. I actually needed a forked version of fusepy, not the official one.

Nice tool. Can anyone make a windows gui?

it's been suggested to me before, I just didn't get around to doing it yet because gui development is way more difficult than a command-line interface.

Hi, i tried using the program on my linux and windows machine, but all the python scripts give an error. I included a screenshot. thanks for any help anyone may have. i have python3.6, the forked fusepy, and the pycryptodomex.

would this work for dsi nands?

Trying to use this to read my nand backup to get movable.sed, and then extract some saves off an SD backup. A little unsure about the usage of the 'mount_pount' argument. No matter what the mount point is, it always opens up into this. Do I have to do another step to mount the files in this folder, in order to get my essentials.exefs off the nand backup?

Edit: after googling around and finding the reddit announcement page for this tool it looks like "mount_point" is just the location of where the virtual is mounted to. Not really clear wording for that in the documentation.

So how would I go about extracting my essential.exefs from the backup to get the movable.sed?

mountpoint is where the virtual files would appear. on Windows I would suggest a drive letter like F:

mount_nand currently doesn't show the essential.exefs as a separate file. what you could do is mount ctrnand using a tool like OSFMount, which can open FAT filesystem images on Windows, then get movable.sed from \private\movable.sed (if the file here is the same one as essential.exefs). in any case I will try to get essential.exefs to appear in the nand mountpoint.

Thank you very much for this help. I was able to get the movable.sed using OSFMount.

Looking at the original release thread and seeing how far this tool has progressed at this point is a testament to how people like you are keeping the 3DS homebrew scene active with updates and tools that no one has seen before.

late response but, if the crypto of a DSi nand is not too different to DSi partitions on 3DS, it could be done.

the commit history would probably show the progress better, but thanks anyway

So I wound up mounting my sd card of an old device that I had the movable.sed from. I'm trying to salvage some extdata from it. I can mount it, I can go to the directory and copy some save files, 4 files in sequence. These files are different than if i was to backup a save form JKs save manager, so how can I move these over? Any thoughts or a better thread to ask in?

JKSM and related tools dump the contents of extdata/savedata archives. when you copy directly from "/Nintendo 3DS" (and decrypt the files, which fuse-3ds does), you get the raw containers the files are in. if you want the files from inside, use https://github.com/wwylele/3ds-save-tool

Awesome work! Now my question, probably asked a lot and answered 100 times, is there a way we can use this to extract an LFCS from a NAND backup without xorpads?

if you have the OTP + CID, or an essential.exefs (which contains both of these), you can use this.

So I would need the OTP + CID from the console I want to explore the NAND backup of?

 

[ihaveahax]

How?

do you have the OTP as a file, and NAND CID as a hex string or file? or, do you have essential.exefs? or is essential.exefs embedded in the backup (from gm9)?
