So, the actual issue is MAME automatically cuts out the overscan areas, often seen on a display from a console's output, on the left and right sides of the screen. Consequently, it then stretches the remaining area horizontally to fill the display aspect ratio.
Is there anyway to have MAME display a console's raw image output as it would appear under original hardware, subsequently, then being able to adjust overscan visibility, rather than automatically cutting it out completely and stretching the image?
