    I am having some trouble with animation. I want to display about seven
small figures (about 16x16), each with at least 16 colors on a 320x200
display. Now, I have seen this type of thing done in various games, such
as Emerald mines, space ranger, and other things. I want the figures to be
updated 60 times a second, to coincide with the display rate.
    If I use sprites, I am limited to 3 colors. If I use attached mode, I
have 16 colors but only have 3 sprites to work with. I want to be able to
display as many as seven figures on a line, fairly close together. Will the
gels system handle this? Can the copper write to the registers on the fly
fast enough?
    If I use the blitter to do the figures, I have all the colors I want, but
it takes about 1/60th of a second just to do it, and unless I use double
buffering, I get transitional flickering as the separate planes come in.
    I am at my wits end. Can these figures be done honestly, without having
to go to the hardware directly? I would like to be able to use system routines,
if possible.
    Thanks in advance for any help or advice.....
