I upgraded from 164 to 186, and am trying it on XP first before I go to windows 10. For the most part everything is working great but with the removal of the "frogger" patch in 169, it is choosing different resolutions for those vertical games reported out of mame as 762x224 (frogger, galaxian, scramble, etc....). Trying to force it back with -resolution 400x256 does "almost" work but I'm noticing the test patterns thrown up by galaxian and scramble are missing a tiny bit of the right edge. I don't really notice it when playing the games but clearly there are a couple vertical lines missing.... Is there a way to configure groovymame so that the entire field is shown or would it be better just to go to Windows10 and enable the super resolutions?
