Example

Dump mlc from backup

wfs-extract --input mlc.full.img --output dump_dir --type mlc --otp otp.bin

Dump USB device under Windows

(Needed to be run with administrator previliges, so run from privileged command line)

wfs-extract --input \\.\PhysicalDrive3 --output dump_dir --otp otp.bin --seeprom seeprom.bin

You need to replace PhsyicalDrive3 with the correct device, you can figure it out with this PowerShell command

Get-WmiObject Win32_DiskDrive

Inject rom.zip

wfs-file-injector --image usb.img --inject-file rom.zip --inject-path /usr/title/00050000/101c3500/content/0010/rom.zip --otp otp.bin --seeprom seeprom.bin

Mount USB device in Linux

sudo wfs-fuse /dev/sdb /mnt --otp otp.bin --seeprom seeprom.bin -o default_permissions,allow_other

(Note: In MacOS you must provide "-o default_permissions,allow_other" argument for wfs-fuse)

Build

Requirements:

• Visual Studio 2022 17.4+ / GCC 14+ / LLVM 17+
• CMake 3.20+
• Ninja

Additional requirements for wfs-fuse: (Linux/MacOS only)

• libfuse

To build:

git clone https://github.com/koolkdev/wfs-tools.git
cd wfs-tools
git submodule init
git submodule update
cmake --preset default
cmake --build --preset release

Windows:

Visual Studio contains all the requirements for building You can just open the wfs-tools directory with Visual Studio and build the project

Linux

sudo apt-get install git g++ cmake ninja-build libfuse-dev zip

Mac OS X

Currently only building with LLVM is supported
Install Homebrew

brew install cmake ninja pkg-config llvm macfuse

Build using the installled llvm:

export CC="$(brew --prefix llvm)"/bin/clang
export CXX="$(brew --prefix llvm)"/bin/clang++
export LDFLAGS=-L"$(brew --prefix llvm)"/lib/c++
