This is a very nice page, but I am currently writing an emulator myself and came to the point where in pong the ball has to be removed and redrawn, like here, and in pong2 there is a vertical line wich should stay but gets removed by this code.. I wonder if there is an easy to figure out when to remove the previous draw and when not?
