There I done did it
I managed to plug open the compression. I started with the mugshots in the /sf/ folder and looked at the pixels and hex values for about two days without any success. I implemented some LZ10 decompression in a program and could get the battle backgrounds, but these things here use a different compression. Magic 0x40, I assumed a special form of some LZ stuff. Turns out it wasn't!
What they used for the mugshots and battle animation frames (in /b/) is some zero redundancy compression - a series of zero Bytes (0x00) in the data get replaced by a single zero Byte followed by a byte giving the amount...
The battle animations are in some container format I just managed to understand.
This basically means I can enhance my FE:SD converter program so it can read the raw files, decompress the parts in question and output the frames as PNGs. However, I'll have to leave for the rest of the day. I'll see if I can work on it during the train rides, though!
Afterwards, we'll basically be able to batch-convert all these animations, I suppose! Yay!
PS: Mugshot automation is done. Next up are the battle animations... heh!
