Squishy-Stretchy picture on my Hantarax Polo and ArcadeVGA

[IntruderAlert]

I'm having some trouble here
I ran the res utility in mamewah to set all of the games to the ArcadeVGA settings of 640x480 and under
but some games end up kind of stretched out in the middle and squashed on the top like this pac man version at 256x224
Notice the score across the top.
and Pac Man and friends look a bit tall.
However, If I let the screen do a vertical roll you can see the score appear as normal in mid roll.


and without making any monitor adjustments, other games like pheonix at 248x208 end up looking like this:


If I set the monitor settings so that pheonix fills the screen, pac man will run off screen.

I think you need to disable 'keep aspect' in the mame.ini
