I have no idea. It's done that since I first bought the donor game and nobody can figure it out. I think it's a problem on the CPU, but it's been on the back burner. The original game was in very sad shape and really it still needs some regular pinball type repairs.
Quoted from dgoodspeed:
Still can't get over it....simply amazing. I would love to know where you found all the information on how to do such a thing.....
I just sort of made it up as went along. Some trial and error was involved.
Quoted from toyotaboy:
Does your blog go more into depth about setting up the mp3 trigger? I get re-using the switches on targets for sounds, I get losing a ball and having that switch detect lost ball and play an appropriate sound. I still don't get:
1. what causes the music to change (almost seems as if it's on a random loop, and when one song ends, the next one plays).
2. how you tell it the game is over so it can play the venkman theme as standby music
Any chance of bringing this to chicago expo?
I can answer any questions you have about this. I may provide a more details guide/photos in the near future.
1. The music doesn't loop. Completing the lower drop target bank triggers a random quote and a random music track. There are 4 alternate tracks and 20 quotes it picks from each time you complete the bank.
2. Magic and illusion. The 'venkman theme' is on the same track as the ball drain sound effects. If another ball is ejected the track is cut short before it would start playing. If the game is over it makes it to the song because another ball hasn't kicked out.
No plans to bring the game to Expo, unfortunately. I won't be able to make it.
They know where to find me.
