Play it for an hour last night and it worked flawlessly.
The moon magnet feature is novel, a bit like THING on TAF when you spell THING and he takes the ball for a bit. When it is activated, it takes the ball and returns it to the shooter lane rather than lets it return via the ramp.
I will add that this machine had been "repaired" or the IRL540N has heated up so much the tracks have been damaged. Each time I had to replace that chip I was worried it was the last time I would get away with it, I think I replaced it five times in the end.
Now onto the GI lights that don't work even with new bulbs. As one of the bulbs had no glass on it, I suspect it has upset something up circuit.
