@tyalie Ah it's not standard byte-aligned CPU/microcontroller machine code?
Do you have any clue to tell whether this may be using a LZ derivate if it is bit-encoded?
For machine code binwalk -A allows to guess architecture through searching for common opcodes and binwalk -E allows to display an entropy graph so that you can check easily for encryption or hard compression

@lineplus hmmh. Maybe the entropy graph could be interesting again. But I once looked at them before. Specifically it's about this one: The Brother label printers have an update format that is easily breakable and so far I found their background images and such, but I'm sure that there must be some way to update fonts. They did that before. So I kinda assume that I just haven't found the location yet where they are put into. But each mono codepoint is only ~12x12px… https://github.com/tyalie/brother-pd3-modifier
