Hacking [RELEASE] wfs-fuse - Mount Wii U USB drives on Linux (and MLC dumps)

[EyeKey]

In continue to my last tool, wfsdump, I wrapped wfslib with fuse. Now you can mount WFS USB and MLC dumps on linux, (currently in read only mode)

Source code

Build:
Install the requirements

sudo apt-get install git g++ make libfuse-dev libboost-dev libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libcrypto++-dev

Clone the repository:

git clone https://github.com/koolkdev/wfslib.git

Enter the directory and run the Makefile:

cd wfslib
make

Usage:

usage: wfs-fuse <device_file> <mountpoint> --otp OTP_PATH [--seeprom SEEPROM_PATH] [--usb] [--mlc]

options:
   --help|-h             print this help message
   --otp|-o PATH         otp file
   --seeprom|-s PATHH    seeprom file (required if usb)
   --usb|-u              device is usb (default)
   --mlc|-m              device is mlc
   -d   -o debug         enable debug output (implies -f)
   -f                    foreground operation
   -s                    disable multi-threaded operation

Example:

sudo wfs-fuse /dev/sdb /mnt --otp otp.bin --seeprom seeprom.bin

When writting into an archive will be implemented, it would be good to possibly convert to FAT32.... But useless for now since mocha doesn't handle well FAT32 (HUUU in fact it's nintendo FAT32 driver who is shitty )

Great job anyway

@EyeKey you're a rockstar!

IIRC, a effective WiiU-FS access (with read) mean a Browser-less haxchi No ?

Well U either need a dump of your wiiu and/or a hardmode to access the files of your wiiu

 

[lexarvn]

Wow! This is kinda amazing! Since the wii u formatted hard drives can be read now, any possibility of being able to partition a hard drive for wii u/vwii simultaneous use? Don't know the details of why it was said that it couldn't be done beyond not knowing how to even read wii u formatted hard drives.

I guess the other question would be if write access is achieved, might it be possible to put other files on it and have homebrew apps in vwii read the wii u formatted hard drive?

With a USB drive with a DS gaùe on it, nope, u can put haxchi.

DS what? Never heard about that.

BTW I think USB to write into the wiiu will break it (full dump). So only hadmode

sry didnt paid attention, DS Game,
And im talking aobut writing into the USB formated WiiU drive, put your legit DS game on it, edit it with haxchi on PC with a WiiU-FS, you're done.

Anyway it's impossible you still need an entrypoint to dump your seeprom and otp.

Yeah but maybe in a near future, we can figure out a way to get rid of that barrier , would be cool for 5.5.2s without haxchi installed before, not my case but it would be neat ! ^^

Maybe we do some comparisons for testing? Read the DS game with HaxChi installed from a system with HaxChi working and compare it with the same DS game on a 5.5.2. I don't know if this would work since there are signatures and whatnot but wouldn't hurt to try

This is would be literally the perfect setup. Make a Wii U Partition alongside an NTFS for Wii and a FAT32 for Nintendont. I'll keep my fingers crossed. Eye have faith in you @EyeKey .

I'm surprised that nobody tried this with Mocha's FAT32 feature, since the only way to move WFS formated drive titles to a FAT32 drive was with ftpiiu everywhere.

Hi

Could I recover my save files with this tool?

Thanks

Then I execute sudo wfs-fuse and it says command not found...

I really need to use this software to recover the save files from my wii u usb stick. I need to mount it in my computer and copy the save files of some games at least. The console tells me there is a problem with the usb device and forces me to restart the system. Can anyone give me a hand please?

The makefile doesn't install the binaries, so you probably need to run sudo ./wfs-fuse/wfs-fuse [arguments..].

Hello, i just finished the makefile procedure and was trying to load my usb pendrive to recover some data that i needed before i formatted it to a filessystem that i could use with my pc to store files. i'm using the example string in the main post but when i try to run this the program gives me the error "Failed to open OTP: KeyFile: Failed to open file". how can i solve this? I'm using ubuntu 18.04 with kde plasma on a vm with 2GB ram and a 10GB virtual hard disk with plans to add another for the transport of the data that i have on that pendrive.

Hi and apologies for gravedigging yet another thread, but in this case I do think it is better to continue the original thread than start a new one.

I have only now had enough time to familiarize myself with the Wii U scene, and I hope not every developer has abandoned it yet. I for one consider Wii U a great console, a step forward from Wii which was my previous favourite console (and I still have a big backlog there).

I managed to compile and run wfs-fuse on my first try on Linux Mint 19. Congratulations to EyeKey! I still wish we could have best of both worlds, all Wii U and vWii software on one HDD, readable (and hopefully directly installable) by PC.

My concerns of the current situation are that I lost one HDD on Wii U and a BOTW save with it. I also have some problems with the new HDD that is not powered, maybe there is a problem with the Y-cable but sometimes the drive works and sometimes not. Today it didn't work, so I installed wfs-fuse to check if the drive was still readable (and it is!).

I haven't tried yet, but I think that at least with wfs-fuse we should be able to backup (and restore) the saves more easily, am I correct? Even if reinstalling the games on a new drive is a chore, at least it is lesser evil than losing a save. But with wfs-fuse, I could also back up my installs so that after formatting a new drive on Wii U, I could just copy the backup to it, correct? Has somebody already done this?

Is there a Windows port of this? Maybe something wrapping the lib with https://winfsp.dev/ ?
