For some reason the 'rol $46' instruction outputs the original data
followed by the new result, so I've had to employ a horrible hack.
When playing, you must hit Z at the start of each ball, or you'll get
no points. When the ball indicator goes out, your game is over.
At the start of each ball, the display will be flashing. You need to
hit Z, and then you can get a score. When the ball indicator goes out,
your game is over.
Game doesn't have any backup battery, so all info is lost at poweroff.
If required, a fake nvram could be used at 00-3F (like PinMAME does).
