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? -John K.
