ADVmame is slower. But I don’t use it for anything but games that I want to play “cocktail” style. Like old galaga, or Ms. Pacman. So they don’t need blazing speed. It’s a raapi after all. So use mame4allpi for all your more graphics intense games, and only use advmame for the ones in which you want the screen flip. For me, that’s about 30 games. Like I said, I have a separate menu option in emulationstation for advmame, and one for mame4allpi.
