Quoted from HowardHurtz:
What's the "target trip switch"? I'm not aware of anything that spots a letter other than the subway so I think you have something faulty.
L7 is the most current ROM. According to the revision notes there isn't much different from L6, but L6 has a few bugs, so I have a feeling there might be some more fixes that didn't make the revision notes. I am curious to see if folks familiar with both have any examples of scoring changes.
Sounds like your last trough opto is intermittently failing. It might be worth it to invest in a new tough opto board set since the old ones have a reputation for failing.
I pulled the drop assy, dismantled it, and cleaned it in the ultrasonic. It's much better now. The Target Trip Switch spots the "D", for entrance to the subway.
I'll probably order spare opto boards, along with spare flipper optos regardless, I know both can fail. Tomorrow I'll replace connectors at trough and clean optos, with the hope that doing that will fix the current issues.
Other things on the to-do are to clean and re-sleeve the coils at left and right kicker, they're both kind of weak, figure out what's making the god-awful squeaking sound at the crane and try to eliminate it, figure out why the crane moves around sometimes besides at the start of multi-ball - I figure it must need some calibration similar to the crane in Last Action Hero.
So far I'm liking the abundance of little challenges and oddball things in this game. Dunno if I'd ever bother with playing a supergame though.
