Express Raider Arcade (MAME) Scoreboard Break

Here, I demonstrate my Express Raider skills by making a quick million, which, as with most classic arcade games, breaks the scoreboard. Observation 1: jump kicking the first man you fight on the top of the train is supposed to yield 200 points, but gives only 100. Observation 2: shooting the money bag carried by the stork is supposed to yield 2,000 points, and speed up your horse; but all it does is speed up the horse; it gives absolutely zero points.
