Wrong answer!

We count on these early adaptors to check out all the new stuff ;D

I tried using scanlines it didn't make any difference.  Also the ultimarc site says scanlines should be turned off.

That's because scanlines needs extra lines to work.  If you run at ~4 times the res (1024x768 to 1600x1200), then the lines can be drawn between the "real" game image lines.  That means if you run at the orignal res, the faked scanlines cannot be drawn.  But the reason for the arcade VGA is so you can run them at the original res.

To restate:
Run at original res, scanlines don't work.
Run at higher than original res, scanlines might help simulate the orignal look.
ArcadeVGA helps run the games at the original resolutions.

 Btw - As far as Ive seen and know..   there is no such thing as a 'scanline'.

 Its just an attempt to simulate the mesh of the monitor
which is called a " Shadow Mask ".

 The older monitors used much more primitive masks.. which were much larger
and thus more visible to the eye.   

 

 As you can see from the closeup of the Turbo car...  the mask appears to look
wavy and crooked.   Its an optical illusion.   The pixels can illuminate half of any space..
and can also be so bright as to project over the mask - thus making it appear that the
mask isnt there or is wavy.

 The mask coupled with other factors such as where the actual r,g,b locations are
in relation to position..  create a look that is far different than any simulation currently.

 There is color bleeding, and blending..  and this is also not simulated.   Which is why
the colors in the arcade monitors look so very different from mame on a pc display.

 Hopefully someday, someone will create a program that will accurately simulate this effect
in realtime.    Being that we now have dual core processors..  its actually a proposition thats
probably feasable now.   Or, it might be something that sepearate hardware could do...

Let's not misinform anybody here;  Horizontal scanlines are present in any horizontal raster video signal, but not in vector.  Whether or not you can visually detect them is up to the quality of the signal and the quality of monitor.

Closer attempts to simulate the mesh of  monitors such as the aperture effects and rgb group effects (triad quad, etc.)  are available now with some versions of mame.  They don't bleed or vibrate like real shadow masks or aperture grills, though.

Yeah, what he said.
