Nice work so far, Leon!
Thank you Martyn
I added 16x16 pixel sprites with 15 colors + transparency, video mode independent.
Still in development and testing phase.
Up to 31 sprites in a 4K memory block.

Awesome! Are you collaborating with any of our resident software gurus on developing the required screen-driver updates or have you developed the code yourself already?
Wishing you every success!

No, I am alone but for now there is no need for drivers.
The truth is I don't have much of QDOS system programming experience so some features I have in mind will take long to finish (if ever).

Are you storing some sort of pallette / attribute map in the 16K before the screen?
Quite impressive to see a QL delivering so much colour
