A toolkit that can extract and repack BFN font files.
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.
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.
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
Thanks to とりぽっぽ for inspiring me to make this tool.
Thanks to RenolY2 and the Editors of the CloudModding Wiki for their information on the bfn format.
