After some board work on the sound board of my old Black Knight, sound is working, but the wrong sounds are playing. For example, the left spinner triggers the laugh that you should only get when the magnasave fails to stop a ball from an outlane. Hitting any drop target plays the "One enemy cannot fight the Black Knight again" that should play when the game ends. Sound is crisp and clear, but the wrong sound are playing. It's kind of fun, but I'd like it to work correctly. Any ideas on this one?
