I suspect the problem is in the way stars are handled in connection with the data struct... I still haven't found the exact problem though. :( I'll keep working on this tomorrow
No.05442 etabeta Developer Jan 7, 2010, 07:27	it turned out to be a 1-line fix. the problem was in MAME init order: the total_stars number was correctly set at video_start, but then it was put back to 0 at machine_reset (which happens later). as a result, these games thought there were 0 stars to draw in place of the correct number.
