I've fixed the "screen tearing" problem I had on my Arcade monitor by turning Vsync on on the mame.ini file.
I also have made the changes below as suggested (in red).
Now I'm having like a "jump" in the sound/music from time to time, and it's pretty annoying. I have it on every game from Frogger to SF2.
If I turn off Vsync the sound is perfect.
If anyone knows how to solve this problem it will be very helpul.
