I got the construction down! That's the cgg files, tomorrow I'll get onto the cgs ones and making GIFs. I can also make it spit out strips instead of GIFs, which should be easier for sheeting up.
EDIT: I forgot to mention, there's also code for stuff like rotation and blend filtering (which I still have to put in). Although this would produce the sprites as they appear in the game, it would taint the "pure-ness" of the actual pixels. So I would suggest submitting the parts as separate sheets in addition to these, even if they're not as directly useful.
