Hi,
I recently purchased and reconditioned a STTNG which is playing amazing now. But I've noticed that the Neutral Zone missions (Ferengi/Romulan/Cardassian) don't always start when they should. After hitting the NZ targets 3 times all 3 lights flash and the mission should start the next time the ball hits any NZ target and drops into the NZ hole. But often I'll hit the center NZ target (which triggers the sound effect) and drop into the hole but the mission doesn't start - instead I just get a shuttle flying away animation on the DMD.

I've tested the center NZ target and the switch works perfectly no matter where the target is pressed. The game ROMs are LA7 (which I believe is the latest). Has anyone else noticed this problem or have any suggestions?

Thanks!

Thanks, I'll try that.

mrq - thanks for the detailed explanation. And thanks to everyone else who has contributed!
