Ah... the magical attraction of contests...contest ?
As I understand it, a title screen would basically be one single giant sprite. No, wait. An object can be 32 "Byte Wide", so that is 64 pixels in "160B", right? So I'd have 2 64 and 1 32 pixel wide sprites.
don't think in sprites, think in zones...a zone can be at most 16 scanlines high, so you have to divide things up vertically aswell, not only horizontally...
Aha. Phew... interesting techniques here...
I understand Dans docs thus far that I can have 4 color bits here per pixel in "160B", but nowwhere it says which bit combinations target which of the 24 color registers.
all this is explained (nicely) in the atari 7800 software guide: http://www.classic-games.com/atari7800/softguide.html
Ok, thanks for the pointer!
