I know just what you mean. I have used the same algorithm as used in the
demo which was supplied on the update disks etc. I just can't seem to
figure out what causes the flicker. It would seem that the update doesn't
quite beat the vblank but the code is so simple it doesn't seem possible.
I did find when I was writing the scrolly that the further down the screen
the scroll was the better. If you have the scroll at the top of the
screen then you haven't got a hope.
Any one see what causes the flicker in my proggy??
