Quoted from XpadreX:I asked a question, which did not imply that I knew the answer. Buttons on a lockbar do not seem beyond the abilities of many on Pinside, who frequently mod games to add features. Clearly, you aren't the expert whose Intel I sought.
...and if I could do it, I would not have asked a question, but rather would have made a statement. Alas, I would have been directed to another thread to provide my response, as evidently info cannot be repeated under any circumstance.
The rules are deep!
So you can add the lockdown button pretty simply. But not the code.
