Hey Oldgoat! First of all, that schematic image is awesome. I've never seen something like that before, but that's super cool. Where'd you turn that up?

As far as diagnosing and fixing your problems, I'm sorry to be all "tl;dr" on you, but you could please do me (and presumably someone who might be able to help with your problem) a favor -- could you list out each issue separately along with the circumstances under which it occurs?

So what I understand right now is:

- right pop bumper works, and scores, but does not chime
- center target bonus doesn't reset properly (some of the time -- confusing after this point)
