I have had a search and noticed quite a few people switching ArcadeVGA setting to off even though they have one. What I would like to know is though, I have run a mamewah resolution util and generated INI files for my games, if I test them from Mame directly I get no problems (apart from some odd stretches with strange resolutions) and I can play vertical shooters no issues of rolling screens. However, if I enable the Use ArcadeVGA option in Game Ex config, I end up with it trying to display resolutions which appear to be out of spec for the monitor. Am I doing something wrong here?
