sorry, I can't help you but I have a similar problem. When using FBAx the bottom and the top of the picture (sometimes even the left and right part as well - not that noticable) are off the screen. Therefore the credits counter is cut off or even the press start/player 1 / 2 on top of the screen is not visible. Adjusting the screen in the setting doesn't change anything. It's just like FBAx's picture is to big to fit the screen. In mameX the same game perfectly fits the screen only FBAx seems to be giving me this problem. Is there any.ini file I have to change or some kind of setting I have yet to find. Any help would be greatly appreciated. Thx.
