finally got to my barracora project i bought 2 years ago. i have it booting and playing with a couple issues.
1) in switch test all switches work fine. during game play, the locks will be lit, when you lock the balls (in 2 ball play or 3 ball play) when i plunge the other ball, most of the time it will not release the balls in locks. it will show "2" or "3" on the displays preparing for multiball play though. if i drain the single ball in play, it WILL kick out any locked ball. the saucers kick out the balls instantly in one ball play at any time a ball drops in them. the switches for both saucers work fine every time in single ball play, no issues and switches work fine in test as well. it only acts this way during multiball. one in a while it will kick the balls out from the saucer for multiball, but its rare.
2) sometimes the gate that lifts up and allows the ball to enter and collect bonus in the upper saucer or lock a ball there, will not raise. once again, in test it raises every time.
