A moon has no air, so a sideways drift never stops by itself and stopping one means cancelling the velocity EXACTLY. That is not hard to do; it is hard to do blind, which is what it was - a number nothing on the screen said anything about. So sprite one is a bar whose width is the drift. It runs right from the middle of the screen for a rightward one and left for a leftward one, so which way is as plain as how fast, and stopped is the one state with nothing drawn at all. The whole of it is a target width written once a frame; the device stretches one tile into it and the program draws nothing. Sideways thrust is one a tick rather than two. At two, the smallest correction available was twice the size it needed to be and overshooting was the normal outcome. WHICH ZERO MEANS NOTHING TURNED OUT TO MATTER. A target width of nought is the NATURAL width, not an empty sprite - so a bar with no drift in it came out eight pixels wide, sitting at the middle of the screen, saying "stopped" in the same shape it says "drifting slightly". What draws nothing is a SIZE of nought, which is the other zero in the other byte. Both meanings are deliberate and documented and it still caught me out inside a week of writing them down. The check for it earned its place by failing on that before it was found, which is the best evidence a check can offer.
