I have an older version of MAME running on my cocktail... I think it's around .113 or so....
I noticed last night while playing 2 players with some friends that some games (most Atari, some others) were screwed up for player 2... The screen image "started" about half way down with the top half showing at the bottom and the bottom half showing at the top.
This only happened for P2... not P1... and my cocktail is a vertically oriented cabinet...
Does anyone know if this bug has been squashed over the last year or so (since my last update)?
I did a quick search at mamedev and found nothing (too much).
