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

[ihaveahax]

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

You replied prior to me editing my post.

yes, you need those so the NAND can be de/encrypted.

 

[OrGoN3]

Thank you. I have the OTP but not CID and I doubt the essential files are in my GM9 backup, as it's old. Thanks for your assistance and thanks for this awesome project!

will this fuse kill the Hostage?

But really, This is cool, nice job

 

[ihaveahax]

lots and lots of refactoring and updates recently (most "under the hood"). I made it installable as a module, so it should be much easier for Windows users to use. I also added an ExeFS mount with .code decompression (automatically if you're mounting an NCCH/CCI/CIA file or CDN dir!).

the README has also gotten many changes explaining a bit about how it works, how to set it up, and some command examples.

After about 7 months since the first commit, fuse-3ds has its first beta release!

The most significant addition has been a simple GUI, which should hopefully make it a lot easier to use for those who don't know how to use a command line.

There is also a single-file version which contains everything needed to run (WinFsp must still be installed though).

Please test it and file issues at the issue tracker. You can ask about it on this thread or at Nintendo Homebrew on Discord.

It's up to 1.0b3 now, and I've posted a new tutorial for it. Please check it out.

This program is awesome! I finally found a solution that does not require me to use cmd on wine.

Is it possible to add or replace content for a .3ds/.cia file with this program? It doesn't seem like I am allowed to do that.

these formats are read-only, you need to use proper tools to rebuild them.

I put up v1.0b4 with a context menu entry for Windows for fast access, among other things. Enjoy: https://github.com/ihaveamac/fuse-3ds/releases

 

[ihaveahax]

Since my last post, I released v1.0b5 and v1.0b6. The new additions have been drag & drop support, update checking, 3DSX homebrew mounting (SMDH and RomFS), and many other fixes and changes. https://github.com/ihaveamac/fuse-3ds/releases

 

[ihaveahax]

There is now a v1.0 release. fuse-3ds is out of beta now!

Since v1.0b6 there has been:

• Easier setup for boot9 and SeedDB
• More GUI additions like advanced options
• Nintendo DSi NAND image support
• Many other fixes and internal changes

You can find it at GitHub, or the GBAtemp Download Center.

Updated to v1.1. CID isn't needed for 99% of 3DS NANDs anymore, the Counter will be automatically generated.

@Xyphoseos @OrGoN3 you should find this useful if you still need it.

@Jay1Gamer late response but DSi NAND mounting has been in since v1.0 so you can try that if you still want to.

Wow, my good friend. Thank you very much for the alert. And more importantly, thank you for continuing you work! I shall give this a go! o/

Edit: Success! It displayed the contents of the NAND image almost instantly. I then followed your guide and used OSFMount to grab what I needed from CTR. Thanks again!

@ihaveamac Is there any chance fuse-3ds could include an option to recover any fragments of factory titles that may still be present in a NAND dump, but that may have been marked as 'deleted' by the filesystem? Perhaps a 'Recover file fragments and deleted files" option?

I have been trying to recover the factory CTRAging app using the fff*ck.exe from this thread:-
https://gbatemp.net/threads/request-ctraging-3ds-debug-app-research.411704/
However since my NAND dumps were made with the latest Godmode9 I dont have any xorpads, so I cant get the exe to work

Any help would be much appreciated.

fuse-3ds wouldn't search for it itself (the process is very complicated and doesn't fit in this project), but it can assist. fffuck only needs a xorpad if the NAND is encrypted. What fuse-3ds can do here is provide a decrypted image that you can use it on. So try it on ctrnand_full.img, since it acts as a decrypted CTRNAND.

Thanks, I just tried and unfortunately it just displays:-

Dump contains encrypted FAT16 partition. Please supply xorpad.
Usage: fffuck nand_image [xorpad]
xorpad is only optional if nand_image is already decrypted.
Press any key to continue . . .

I tried renaming ctrnand_full.img to nand.bin and that didnt work. I also tried editing the run.exe to look for ctrnand_full.img instead, but that also failed. Might you have any other suggestions?

Try ctrnand_fat.img since that contains just the FAT16 partition.

 

[Razor83]

Try ctrnand_fat.img since that contains just the FAT16 partition.

Ok, that gives me a different error:-

Error: NAND size is uneven, should be a multiple of 0x2000
Press any key to continue . . .

 

[ihaveahax]

Ok, that gives me a different error:-

It probably expects a full NAND with a decrypted CTRNAND in it. Are you able to mount ctrnand_full.img with osfmount? Maybe fffuck could be edited to not require the full NAND, but I don't know yet.

Yes I can mount ctrnand_full.img with osfmount, although I do have to select the FAT partition.
Unfortunately i'm assuming viewing the NAND with osfmount wont display any deleted/fragmented files?
