[comp.sys.amiga] Scroll on 16 color WorkBench

drtiller@uokmax.uucp (Donald Richard Tillery Jr) (09/17/90)

I am currently running 2.0 in 16 color mode (see my Iconize program in
abcfd20.larc.nasa.gov for why).  When I am using a shell the scrolls are
atrocious!  What I noticed was that the shell generally uses only the basic
4 colors of the palette.  Is there any way to modify the scroll routine of
the Shell to only blit the first two planes and ignore the others to get
scrolling speed comparable to the 4 color mode?  I realize that some limitation
may have to be put on the shell to dis-allow the other 12 colors of the
palette but since the average user would only be in 4 colors anyway, this
should present no problem in actual use.  Could someone help me here?
