Ok, I've just added an EMReel to handle the backbox GI effects. I'm still not sure about the exact parts to light up, though. I used the bottom "blue chip" area on the backglass separated from the top part with the running doctors, etc. Again, these backglass GI effects are not like typical Williams/Bally tables. They actually do something during the game other than go off during a Tilt. It can be a little distracting sitting to the left of the table, so I've put yet another GUI disable box in the F6 Options menu so you can disable the playfield GI effects separately from the Backbox ones.

The only thing left I might possibly add is a few in-between "steps" to the Time Expander movement. That's a heck of a lot of code and parts for each frame, though and it still wouldn't appear "smooth" like the real thing slowly moving upwards, so I don't know if it's worth it or not. It won't be today, that's for sure.
