ROM Hack Hatsune Miku Project Mirai Graphic and Graphic Animations file format help

[Stewie1.0]

I've been having trouble figuring out the format for the aet (graphic animations and sometimes others) and spr (graphics) files (.bin), because there isn't a format header in them (except in the spr graphics, which is just multiple CTPKs for the textures). So, can someone help me try to figure out the format for these files?


Im sending 2 graphic animation files because some have different types of animations

aet_pv028.bin (Finder (DSLR Remix - re:edit)'s graphic animations)

aet_pv071.bin (Invisible's PV graphic animations from Mirai 2)
https://www.dropbox.com/s/z4h0sfpvocpmdmq/aet_pv071.bin?dl=0

spr_ae_pv071.bin (Invisible's PV graphics)

This is how one of the graphic animation files looks like at the beginning (Finder's). Spr ones r similar to this too, but not exact. I even looked everywhere in these files, and still nothing.
