This is for the extensionless sprite files from Dustforce, in the folder content/sprites.

Code:

comtype zlib_noerror
get FSIZE asize

         math OFFSET  = 2

This was tough. Right now all it does is extract the individual image files and gives them the extension .dec. These files are raw 32-bit BGRA, all 102x102 pixels. They're all parts though, so I need to try and figure out how to put them together (the files they're extracted from probably have info). Once I know how I'll probably make a program to extract and convert them into proper images in one go. I thought this script might still be useful though.
