Ok I have tried the resolutions in windows from the galaga utility and basically the only ones that work are the supported ones as listed on the ultimarc site such as 800x600, 640x480, 640x288 NON INTERLACED does not work, 1024x768 Pan does work.
In mame64Ui version .137 I think all settings are correct and I have tried them in the default game options and the actual Game properties, the problem seems to be with the auto setting in the resolution select because if I leave it on auto as soon as the game starts to load the screen goes black, if I manually select the correct resolution for the game, or close if the correct one is not listed then it loads up great and looks fantastic! I have started trying my favorite games to see how they look but its a right pain having to go into each game properties and manually select the correct resolution! Has anyone else had this issue?
Also I note that with manual resolution selected there is only 59hz refresh available in refresh option box,(Im guessing my TV refresh rate) with auto resolution selected I note there is 59,57,53 (and another I cant remember) but as soon as I select one to try it defaults back to auto refresh before i can apply it, Im thinking possibly maybe that MAME is selecting the wrong refresh rate for my TV when auto resolution is applied? if I could force 59hz in auto I think it would solve my problems but I dont know how I can test this theory?

The things I thought would be simple with this build are proving to be the most difficult

Before when I was playing around with MAME on the normal PC on a LCD it seemed so simple to put the guts in a cabinet and play, but when you factor in the arcade VGA 15khz, VGA-scart hook up, TV resolutions, overscan and correct pixel ratios and resolutions,front ends etc it becomes much much MUCH more complex for a newbie like me LOL.

Im getting there but its a journey!
