Ok, update to my problem ... I can get Arcade OS to display great, and some of the games will be fine when loading (a handful of them), but the majority need a veritcal hold adjustment done to them ...
I'm using advanced mame also and in the advcfg mode, all the modes display ok except the higher resolutions need the adjustment ... maybe I'm having trouble understanding how to tell it not to use the high resolutions?
Any ideas?
