in 256-color mode too. doesn't depend on the 16/256 color distinction,
rather on the use of planes.

I'm wondering, do non-plane 16-color modes exists?... it would make
sense.
 BM> Personally, I prefer the 256-color mode... have you tried to write a

hmm I'll have to check about this, i'm curious about the 16 one; 4,
figured that one easily; maybe there's a 1-read too, but i'll have to
browse my docs...
how often do you GetPixel??

Besides, thinking you were talking only about the 16/256 color
distinction, thought that everywhere a planed 256 is fast, a planed 16
is twice as fast because it's twice less data; but there is the
disposition scheme consideration... a pixel in 16-color is on all
planes at once while it's on 1 plane in 256-color.
