It's completely QMC2 related, as that's how I run MAME, and I'm unable to figure out how to configure QMC2 to run MAME like I want.

The prescale option doesn't work - I set it to 2 with no effect. The game is not scaled. I figured i wasn't using it right, but if that's how you do it, I guess I need to file a bug report. Note that, if MAME64.exe is run from the command-line, the prescale option also doesn't work, but the screen is always scaled by 2X - it's twice the size as when the app is started through QMC2.

I've got the windowed option checked, and the maximized option unchecked under Emulator Tab/Video/window, as I want the game windowed and not maximized, and these options seem to work fine.
