Sonic: You could do a logical block fill with an AND mask and then merge the paletted GFX with the JK bits using OR. Still slower than SCREEN5, but at least everything could be done by the VDP.

The problem of finding someone to draw SCREEN11 GFX remains tough and that's probably the hardest problem.

Ah, you're right. However, it is salvageable: you could make an AND mask that is copied using TAND, so you don't overwrite pixels outside of the shape. That does mean you need two separate masks for each shape: one AND mask and one OR mask.

Screen 10/12 is not suitable for the BJ graphical style. I think that the MSX2+ screen modes are good for digitized images (photos, etc.) but not for drawings.Actually, if I take a quick look at these screen-shots, this would work like a charm on screen 11. The sprites could stay the same, and the objects could be made using the pallette colors. That doesn't change the fact that screen 11 is a pain in the ass tho Tongue

I insist ... The original BJ look & feel must be made in SC5. Furthermore, the VRAM is used hardly to store all the graphical data and SC11 screens are double sized (54K instead 27K).

And don't forget something I think is very important: Sc11 implies MSX2+ instead MSX2. The makers of BJ wanted the game running on basic MSX2 configurations (RAM 64K, PSG, etc.)
