That looks like the problem. That said, the same problem applies to many more games than just ATARI/NAMCO titles. I went through my 190 or so cocktail games this last weekend at at least a dozen to 15 or so experienced this issue including non NAMCO releases... all the very same effect as shown on the page above.
I just checked and it seems I have version .137... later than I thought frankly. It seems this happened after .131... maybe I'll try to regress.
