these two pictures are correct but without transparency enabled. So you can't see both on the same screen.



with transparency enabled, many colors become transparent (not only black)



target display.

Anybody got an idea on how to fix such problem with transparency ?

What kind of video chip does the machine you're trying to emulate have? Is it like an SMS VDP but with 2 layers?

Maybe you could use 256-color BGs so that only one color is transparent. It would require some extra work when emulating VRAM writes.

i've found a solution, i've applied on one layer only (too lazy ). Ive duplicated tiles and palettes(colors 0 to 7 = 1 to 8) then i choose between tiles with/without transparency when first color is black or not.
