I decided to make a video demonstrating the mod for Bally Midway MCR games which turns the sound on in attract mode. Enjoy.

Spy Hunter... my cab plays the Spy Hunter theme every once in a while... is it supposed to? If I do this mod, I guess I get all the rest of the attract sounds (engine, shots fired, etc...)
...would using a variable resistor provide any additional benefits?

Thanks for the video, Keith and nicely done.
I have been thinking of doing this to my TRON and SH, but was thinking of using a remotely mounted button (by the service swtich) to make it a little easier to turn on/off from the front. What voltage is running through that resistor and would using a variable resistor provide any additional benefits?

It's supposed to play every once in a while if you have the attract music turned on with the DIP switches. You can check your setting through the menus. I had one that played randomly, and after fighting it for a year or two, I picked up a new CSD that fixed the problem.Spy Hunter... my cab plays the Spy Hunter theme every once in a while... is it supposed to?

The Satan's Hollow I think would drive me slowly insane though, LOL.
This is really neat tutorial/find! Question though, do all Bally/MCR games have odd little white sprite static on them when they change screens or colored lines/garbage on the sides/corners of some of the screens? I noticed it in my tron where I just had the boards repaired. I also noticed this was the case of a few other tron machines i've played recently including the one in this video but just wanted to make sure.

There is one problem with having attract sound in SH. About every 15 minutes or so the "shield" sound gets stuck and will stay on until the next gameplay screen, about a minute or so. I may turn it off for that reason.
Finally found R135 on the schematics, so I can say how and why the mod works...
