Hey everyone, I'm new to launchbox and bigbox I came from hyperspin and there was an option to use a single platform (Mame). I'm hoping someone can help with settings. I am creating a vertical mame arcade and trying to set bigbox to launch directly into games (not platforms). I would also like to have bigbox in vertical view, but it comes out looking funny when the screen is rotated. Any help is greatly appreciated.
