I thought it was done by strobing the HMOVE command at the beginning of
EVERY scanline. I thought that the ladders in Pitfall were made up of the
ball graphic. The Player1 graphic would be the Wall, and Player0 would
obviously be our friend Pitfall Harry.
I figure that this would be easier to do, instead of changing the color of
your Player/missile combo after each missile is drawn on a scanline. One
would have to change HMP0, HMM0, etc on an individual scanline basis, which
could be tough.
Of course, this is just a guess. So are they eccentric HMOVEs, or just
re-colored missiles or balls?
