Wrong aspect ratio in 2D Mortal Kombat games

Hi. I signed up to report something that I'd really like to see fixed in MAME.

For the longest time, the 2D Mortal Kombat games (mk1, mk2, mk3, umk3) have been displayed in MAME with the wrong aspect ratio.

By default, MAME shows them as being 4:3, but this yields a picture in which everything's stretched vertically.
The easiest way to see it is looking at the dragon logo in MK1's character select screen, which of course, is expected to be round, or look at how much shorter the characters look when they're lying on the ground compared to standing (need to drop them by uppercut or knee strike so that they don't fall sideways).

The game's monitor seems to be 16:10 (8:5) as with that aspect the game just looks right.

For anyone using MAMEUI64, you need to go into the game's properties, go to the Screen tab, uncheck "Autoselect aspect", apply so that the input boxes are enabled, and enter 16:10 or 8:5 (exact same thing).

Note that while this fix works fine in MAMEUI64 v0.222, for some reason it seems to be ignored in the latest version of MAMEUI (v0.242).
