Well I’m now an owner of Batman 66. We love the game but we were told by the pinside seller that there was a software bug that occasionally caused the multi ball to fail to kick off when you locked three balls. It looks to me that every single time I lock three balls it never kicks off multi ball. Does that mean it’s probably a hardware problem and not a software glitch as he said? Also found some chipping in the playfield down to the wood that I’m not super happy about and I didn’t notice until I got at home. He said it had no playfield issues. My bad. My lesson.
Machine seems to notice when it’s locked two balls but as soon as you like the third ball it just sits there and then eventually it starts looking for the balls and turning the carousel and after quite a bit it eventually dumped them all out and you just lose the multiball.
