So, as most of us know, .p8 cartridges consist of sections. lua,gfx,map, etc etc. Well, I found this other section named gff. I just wanted to know what it did, since it doesn't seem to directly correlate to anything you can edit. I'm just asking since I'm making a cart generator in Python so I need to know if gff is an important memory region.

These are the sprite flags. Each sprite has a 2-digit hexadecimal number (0x00 to 0xFF) representing the sprite flags for each sprite.

Here's the section in the PICO-8 wiki that covers that:

(The whole page might be of interest to you if you're generating p8 files in Python.)

Cool, thanks for the info! I'll have a read.
