Thank you, we will see in the future for a good Double Dragon conversion.
Please take this Final Fight picture.
I convert almost all the Final Fight graphics to 16 colors, they loose some detail, but I should use on a OCS/ECS version for sure. Maybe you can check and use them for another small and fast version. Then, we can have AGA and OCS/ECS version. In the picture, the dark grey is the color 0 for the sprites. OCS version may have a single scroll.
Have you maked the backgrounds on tilemap?
What do you think?
