Hey folks, I'm gearing up on a vertical cocktail cabinet (mame 135, XP, Mala) and from what I've searched, it seems like I'd keep my windows orientation horizontal (hidden eventually), use the vertical setting of my frontend, and FLIP EACH ROM TO COCKTAIL in the tab> dip switch settings? I've got about a thousand (vertical-US-3button) roms to do, is that really the way to go, or is there a blanket 'vertical cocktail' setting i can use to affect MAME universally?
Sorry I know this is well worn territory, but no ones really come out and said 'yes you'll do all these by hand' in my searches
