I have accomplished a fast scroll, by setting up a super-bitmap, and changing
the x and y offset parameters in the layer_info structure pertaining to this
bitmap and then issuing a CopySBitMap(mylayer); command where mylayer is a
pointer to the layer of the Superbitmap. This IS fast, but it produces a very
horrible color flashing effect when used on a 32 - color image...

Is there any way to eliminate this (or rather any way that someone will tell
me how to eliminate this????) ? I've seen smooth scrolling in several games,
and I'm not afraid to code in assembly, but how do I go about passing the 
pointers to my bitmaps to an assembly language scrolling routine ???

Any info will be appreciated..
