Just as follow up to my previous posts in regards to old code and weird switch issues, wanted to say thanks to everyone that responded as it was a simple matter of upgrading to 1.6 that fixed the original issues I was having. The hardest part was finding a motherboard around my house that actually had a serial port, but the Pin2K software installed and ran fine on Windows 7 32-bit (wouldn't install on 64-bit) for an easy update process.
I also installed these speakers/subwoofer as recommended on a another restore thread as my original ones were cracked and sounding terrible. Decently cheap upgrade and they sound great:

Couple of other questions as I go through and clean up things:
1. Biggest issue I am seeing is the martian green standup target next to the red center targets was very loose and upon further inspection it looks like a small chuck of wood under the playfield where it screws in is missing (1st pic) and target wasn't sitting flush. It also appears the screws that someone used to try to correct this were too long and have pushed up on the top side of the playfield (2nd pic).
Any ideas here on how to prevent further damage to the top side of the playfield while tightly securing this standup target from underneath? Obviously longer screws seem like a bad idea and was thinking I have to either add some filler/shim or take a bit more wood off to get this target flush again as well as some wood glue if the holes are hollowed out.
2. The playfield has some rough spots around the insert decals with the bottom left of the mothership the worst as it also dips in slightly in addition to the wear (3rd pic). The center arrow right below the skip ramp and some of the missile inserts are also worn as well as appear to have some ghosting (4th, 5th & 6th pics). I imagine the ghosting is a lost cause, but as far the decals anything that can be done here to prevent further damage or even replace them?
Thanks again for any help, really enjoying and working on this game.
