Normally, I pride myself in having all of my games in tip-top shape. But recently I've had games go crappy, and remain unfixed. Here's my embarrassing list at the moment. Post yours if you want...

Gottlieb World Series: 1st base never clears. When you hit a home run, you get at least two runs. Have worked on it, but it's not fixed yet.

Bally Fireball Classic: A bunch of playfield lights out. Have messed around with it a bit, but haven't found a clear reason.

Baby Pacman: Sound section failing startup test. I can get it to work by pushing the chips and reseating them, but it stops working again soon after.

Space Shuttle: Lots of weirdness in the sound section. Sound cutting in and out, rapid volume changes, distorted speech.

Diner: Half of the solenoids are out. Hoping this might be a fuse, but I haven't looked into it yet. Also has an IRQ interrupt error when it powers up, and I think this has to do with the display ribbon cable.

Judge Dread: Deadworld isn't moving at all. Gear box needs to be removed, cleaned and repacked. The motor isn't spinning free, so it's just completely stopped.

Cirqus Voltaire: Sling switches aren't reliable. They need to be replaced.

Goldeneye: The opto on the ball trough isn't working correctly, and seems to sense a ball that isn't in place, causing the upkicker there to endlessly fire. Curiously, unplugging it "fixes" the issue and the game works perfectly as far as I can tell, but it needs to be repaired correctly.

Apollo 13: Has had an intermittent DMD in the previous weeks, but seems to be working fine. I did reach in there and mess with some connections, and that might have "fixed" it, but it remains under suspicion.

So that's my list, and I'm ashamed of it.
What's your list?
