Horizontal line scrolling upwards when playing MAME games.

On some of my beatem up games like Final Fight, TMNT, Golden Axe, Altered Beast...etc I see a scroling horizontal line that moves upward kind of slowly.  What is this line...  Is this how the arcades used to do it.  I am using a Sharp TV S-video...

RayB:

Is it an actual LINE, or is it more like a "shift" in the graphics?

If it's more like a shift, that moves up, this is what we call "tearing". The way to fix it is usually to turn on vertical sync (vsync).


rdowdy95:

Is there a way to turn that on in the mame config file I use mamewah as my front end.

rdowdy95:

Oh it could possibley be a minor shift.  Not noticeable when I play unless I start to stare at it.

bump anyone else have anything to add?
