I've been having some issues with this all of a sudden. It started with a table not displaying the score board at all, and some weird graphics artifacts in a part of the playfield.
To rectify the score board part, I had to un- and re-install vpinmame. The score board showed, but the graphics artifacts remained. Not a big deal, cos they aren't really in the way of everything.
However, after this, on exit, I started getting weird behavior of pinmame stopping but the table not exiting to the MaLa.
After un- and re-installing a couple more times, what happened then was that VP couldn't see the roms. The paths were fine. Re-un-install vpinmame and click yes to 'delete all vpinmame registry entries', and vpinmame would see the roms, and load.
So apparently that registry thing is now getting in the way. Not the biggest deal, cos, how often am I doing a complete vpinmame install that it doesn't remember the table's been played? But the table not exiting to MaLa, though seemingly less frequent, is still an issue. I have to stop the process (VP) for it to return.
