The animation is smoother in some games with VSYNC desactivated and Magnification/Minification set to 2 (linear fitering). You can just try and compare with P47aces, Gratia, Gunbird 2... In older Mame versions (BendermameOX for example), the screen refresh wasn't as good as in CoinOp Gold, so I used the VSYNC activated all the time but now we don't really need it anymore. Options I'd like: VSYNC, Magnification/minification Sound enable/disable Aspect Ration Correction That should be enough. A little advice for players: we can also set a value for CPU overclock: ingame menu -> "Remap Gamepad" -> "On screen display" : remap keys here. It can be good for "big" games to set CPU overclock to 75 or 80% cause Mame will more easily emulate a less powerful CPU. In some games like Aerofighters the CPU can be set to 120%: no more slowdowns when a lot of bullets are on screen. Thanks a lot BritneysPAIRS for answering your "fans" ! PS: did you pay attention to the request for Sega32 games ? Do you think it's possible to import Mame 127 or 128 drivers ?
