I'll take the first step and extract all the graphics and see where things stand.
I'll report back here but it isn't clear cut - however I am keen on a "what could have been scenario for the A500".
Indeed, i just checked albatros and there are about 90 frames (89 if I count correct). So even if we assume 48x64x4 then it takes 136704 bytes (89 frames). Also I tried to count maskers frames in MAME and I failed, too many heads, other bodies and so on.. but I assume that there is also about 70 or more frames for one type of maskers. There are for sure 3 differ types so finally 210 frames (one frame 32x64x4) takes 215040 bytes. What about tiles, masks for enemies, balcony, mesh.

Now I see three options:
1. crunch gfx data and decrunch in fly.
2. store some gfx data in SLOW and use processor to paste it on screen
3. increase requirments to 2mb CHIP - best option for me.

Finally I think that I was pretty naive when I started thinking about version for A500 with 0.5 MB CHIP only
