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

Ok, whenever I try to start the gui on linux, it says i don't have appJar (/ the gui) installed which i do have installed. I can mess with the command line, but I would like to know how to fix this problem.

Install appJar manually or install with gui support. This will ensure it installs the dependencies properly.

python3 -m pip install --upgrade --user https://github.com/ihaveamac/fuse-3ds/releases/download/v1.2b2/fuse-3ds-1.2b2-src.zip#egg=fuse-3ds[gui]

Make sure you also have Tk installed (on Ubuntu: python3-tk; look for your distro's equivalent)

installing python3-tk fixed it, thnx you should say to install that in the readme

I have a specific situation here, and I wonder if 3ds-fuse could help me.

1 - I formatted and installed Bs9 in a 3ds running Rxtools. I did not backup the SD saves, believing I could just copy and paste the Nintendo 3ds folder, that everything would be okay. It was a stupid thing. The saves and data were not recognized by 3ds.

2- Basically what I have is an old SD with the files of my 3ds that ran RXtools, including a backup of Nand pre installation RXTOOLS, and the backups done automatically by GM9 when I installed the latest version of BS9.

The question is:

How could I make the saves of my games in RX tools, run in 3ds Bs9 Installed? Is it possible to do this with Fuse? How would it be?

If you have boot9 and your OTP (GM9 lets you dump this if you have b9s), you can decrypt NANDs. Inside you can find /private/movable.sed which includes the SD encryption key. You can use this to decrypt saves if you have the right key for the data you want.

If you have a backup of when those games worked (or possibly even before), you should be able to do this.

Thanks for the answer. My console was at 9.2 and I used the "push button R" method to enter Rxtools. So, as soon as I cleaned the SD with the RXtools files, I used the soundhax and installed the BS9.

I believe the Nand version and essential.exefs are from the backup made immediately after the BS9 installation. Do they serve me? If so, how can I decrypt them? From what I studied about fuse-3ds, it uses the OTP and CID I have no idea how to get them.

essential.exefs contains the otp and cid, which are unique to every console and never change. fuse-3ds only needs the otp for 99% of cases. You can also get otp.mem in GM9 from [M:] MEMORY VIRTUAL.

Try v1.2b3

 

[ihaveahax]

I just put out v1.2 which includes support for Nintendo DS ROM images (.nds and such), plus a bunch of other fixes and changes.

https://github.com/ihaveamac/fuse-3ds/releases/tag/v1.2
https://gbatemp.net/download/fuse-3ds.34706/

I added some responses to the survey here: https://www.reddit.com/r/3dshacks/comments/9ghgoh/

 

[ihaveahax]

It's up to v1.3.1 now, with a new icon, and a standalone macOS application.

v1.3 also added features to skip online updates.

sorry noob qxn, must the boot9.bin and the nand file to be opened belong to the same console? Can't i use any boot9.bin ?

the boot9.bin is the same for all 3ds console revisions. any boot9.bin from any 3ds console will work.

Version 1.4 is out with a new name, ninfs. It now supports Nintendo Switch NAND backups. There aren't many 3DS related changes this time, but there should be in the future.

https://github.com/ihaveamac/ninfs/releases/tag/v1.4

 

[ihaveahax]

I put out some new releases since the last post. Notably, 1.5 can read split Nintendo Switch NAND backups, and 1.6 fixes a write corruption bug in the SD mount.

https://github.com/ihaveamac/ninfs/releases/tag/v1.6

Changes since v1.4

• Support split Nintendo Switch NAND backup files
  • Each part is expected to end in two digits (e.g. rawnand.bin.00, rawnand.bin.01, ...). Any part can be selected, the program will search for all parts starting with 00.
  • The command line argument -S or --split-files is used for a split backup.
  • The GUI will attempt to automatically detect this based on the filename.
• GUI: Automatically detect Nintendo DSi NAND backups
• GUI: Fix oversight breaking automatic detection of Nintendo 3DS NAND backups
• ExeFS: Always show code-decompressed.bin, even if .code is not compressed

Changes since v1.5

• CDN: Support using a tmd file to mount - #36
  • The GUI now expects a tmd file by default instead of a directory.
• SD: Support manual SD key input
  • --sd-key reads the key as a hexstring. It cannot be used at the same time as --movable.
  • The GUI currently does not accept the key as a hexstring, only a movable.sed file.
• CMDLINE: Support --boot9 for loading the ARM9 bootROM from any path
• SD: Workaround write corruption bug
• NANDHAC: Performance improvements to AES-XTSN crypto operations by @luigoalma
• CCI: Remove useless SeedDB option
• Stability or something, I guess.

I'd like to know why does ninfs not need a dsi cid for nand decryption? (is there something to generate it or stuff that needs it only use the consoleid to derive them?)

If no CID is provided, it will attempt to generate the Counter, using a block of known plaintext in the header. In practice, this header never changes, so it's a good target. A similar process is used for 3DS NANDs.

I heard this can be used in place of Nightmare. How would it work as a replacement?

I've never heard of "Nightmare", what does it do?

I could never get it working, but it's a tool that's been recreated for a bunch of different Fire Emblem games. Look up FEFEditor for the Fates version.
