Long story short, the character files in the "chr" folder are in a .aar format, and are very compressed.
Interestingly, the files seem to contain a filename before the palette data (example being the file i'm showing as an example, "ace_bc.aar", which has the string "ace_b.dig" inside it) , and after the palette is some sort of data table??? I can't really tell, I'm not a programmer.
The actual graphics, however, are lz10 compressed, I'll show an example I did with manual extraction, via Hex Editor:
So It's doable to extract everything, just really painful and unreliable and I ever get some offsets messed up so they don't decompress right >_>
If anything can help me out here, much thanks!
