Idea. Since it is generaly un-economical to create a double buffered display for scrolling multi-bitplaned screens to eliminate the annoying flicker, why not try to reduce the flicker somewhat. I think that most of the flicker is due to the delay while an entire bitplane is blitted up and might possibly be resolved by scrolling the display in 2 or 3 horizontal sections (reduce the time that one bitplane is disjointed from it's corresponding pixels in another plane). Flicker would probably still be there, but atleast it wouldn't be as great, or dominate the entire screen. just a thought.
