MAME32 (Windows) ignoring enforce aspect ratio?

[gaexhada]

I pulled up my old mame32u901 folder (with the GUI), opened up Marvel Super Heroes (US 951024), and on my widescreen TV the graphics are stretched horizontally... it looked correct on my old XP computer (now I'm on 7 and will be on 10 by next year) with the same settings, meaning it displayed fullscreen 4:3 with black bars on the side (pillarboxes) on the same TV, now I can't seem to get it to look right again.

I'll attach or link a screenshot of my settings; I got it to kind of work by setting Clean Stretch to None, but it appeared to just crop it rather than enforce aspect ratio. After configuring the interface controls and joystick, I can't get it to do anything other than widescreen stretch no matter what I set.

Any advice? (sorry if my inserted image doesn't look right... it looks all wrong on the form here)
