bfntoolkit
A toolkit that can extract and repack BFN font files.
Building
bfntoolkit requires a D compiler(DMD is recommended), downloads can be found at https://dlang.org/.
Once installed, run dub build in your CLI/Terminal in the
root directory of the repository to compile the project.
Usage
Run the executable in CLI/Terminal. There are two ways you can use bfntoolkit:
bfntoolkit [filename.bfn/foldername]
bfntoolkit can run with only your file/folder name as the argument.
bfntoolkit [extract/repack] [filename.bfn/foldername]
bfntoolkit can also run with an explicit command to either extract or repack, extract is used with .bfn files while repack is used with folders.
Editing the BFN File
At this time, bfntoolkit cannot accurately reconvert the png images into the bti format specified by the bfn, you will have to use a separate tool to convert png to bti.
Wiimms Szs Tools(https://szs.wiimm.de/download.html) is recommended because wimgt can be used to quickly convert all images in a folder with the use of the
batch command provided in the repository
The rest of the bfn data is stored inside data.json in the folder, information on the elements and sections can be found at https://wiki.cloudmodding.com/tww/BFN
