15KHZ on a 31KHZ Monitor
<< < (4/16) > >>

Thats not the way I read it at all.   They are taking 15khz signal and converting it to a way that a modern day PC can express it while still maintaining the inegrity of the original signal.

I mailed Andy how he did this, but I guess this is patent.

But as it stands when you look at the MAME output I remember it showing this...somehow it was proven, but that was a year ago.

Still I am curious how you arrive at the fact that CGA Cards or PCB's are the only thing that put 15khz signal.   Is this how the program works?  Thus Advance MAME?

Fine its only what you said.   Sorry for ever asking anything different and trying to understand.   You have spoken. :notworthy:

He's doing line doubling I believe.  Basically running the same resolution, but at a much higher refresh rate (actually running at 31khz).
genesim:
Hence a conversion is taking place because it starts with the 15khz signal from MAME?

Isn't this actually the exact opposite of a CGA card that output 15khz signal?
