Well, at least you tried it unlike efjayel who never does.  It's not perfect but those that try to help themselves instead of expecting to be spoonfed, help out the community more than the leeches.

I knew certain people would.   ;)

So I'm a leech? Just because I'm not as smart as you I'm not allowed a better explanation? I have ADD. How is that my fault?  :-[

Hoopz:

Work smarter, not harder.  I never said you weren't smart.  Anyone who knows their limitations should also learn how to use a system to make things easier. 

All people ask is that you search before asking sometimes.  You never search and expect people to spoon feed you.  Take responsibility and try to help yourself.   :cheers:

Heheheh. Yeah, no doubt, G.

Okay, here it is. If you set the display_adjust parametre in to generate_yclock, and then give some generally appropriate values in device_video_clock, Advancemame will attempt to display an image accordingly. Very quickly, it takes into account the mentioned parametres and also analyzes your hardware. In this case, I had a PC monitor hooked up. I had clock settings for an arcade monitor, but hadn't set a device_video_format so Advancemame ignored the specific clock values and created a high-refresh mode: something like 31khz by 119.1hz. (If you look in the soft15 thread, SS created a set of modes for this.) This gives real hardware scanlines. In fact, some modes that have been problematic at 15khz, for example the stock soft15 352x288 mode, are smoother at high refresh.

In any case, that's the point of the thread. With some general parametres relative to your monitor's specs - or not necessarily as in the above case - Advancemame will automatically give you a good, if not perfect, display regardless of game, and regardless of monitor. The only caveats I think are those monitors, especially Gateway presentation monitors, that only do VGA or VGA/SVGA. It has to be able to do 15khz or go up to 120hz.
