ArcadeVGA is a video card, that was made specifically for Windows, that allows people to use an old arcade monitor, typically using a 15khz signal.
Most modern PC's monitors consider 31Khz or higher signal, wich given problems with using in a real arcade monitor. Modern video cards typically disable 15khz to prevent users from being used by the driver. This may get this pretty hard to get this to work on a Arcade monitor (even with Advanced MAME).
ArcadeVGA supports many MAMEtm based resolutions, so you don't need any software scaling in most games. But some resoulutions may not work on your arcade monitor, so these may need to be disabled with a resoulution tool.
