Hi there!
Ah... the magical attraction of contests...
Ok, I started reading some of Dan Boris docs and such and am still
wondering about 7800 things but my first task should be something
simple: A title screen
If I simply wanted to display a 160*200 graphic with 16 colors to the
7800, it seems like "160B" was the best choice.
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.
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. I can set one of 8 palettes in the
display list, but that doesn't seem to make too much sense to me, I
guess it gets somehow overridden by the 4 color bits?
Is there sort of like a standart GFX format available for full screen
7800 images? Any tool that'll produce the required data? Any code
available that displays a picture in this standard format? Any examples?
Greetings,
Manuel
