After a recent gameex update, most of the games on my list disappeared. I ran the game list update and it seems like they all came back but I notice I can't find Tempest. When I run mame on it's own, I CAN run tempest (well I only tried rev3 but that seemed to run fine).
I tried adding the word 'tempest' to the do not filter list but it still doesn't show up.
Not sure how to track this one down?
