'auto' has always automatically scaled to your desktop.
It started with 'stretch using hardware' via direct draw, early on MAME development. Then was automatic in D3D, though a software effect or sometimes a prescale value would mess up the scaling. Since the change to D3D as main display mode/deprecation of DD, it's been full-screen.
Scifi frauds. SF illuminates.
