http://docs.mamedev.org/commandline/windowsconfig.html?highlight=prescale

-prescale

Controls the size of the screen images when they are passed off to the graphics system for scaling. At the minimum setting of 1, the screen is rendered at its original resolution before being scaled. At higher settings, the screen is expanded by a factor of before being scaled. With -video d3d, this produces a less blurry image at the expense of some speed. The default is 1.
