Will this converter work on a arcade board?
MonMotha:
Dunno about the quality on that one. I built a similar device a couple years back, but I used a different "main part". Results were EXCELLENT with what I built. S-Video was almost indistinguishable from RGB on a quality arcade monitor. Composite of course looks pretty bad, but that's hard to get around.
I looked up the part that board uses, and I don't think it's quite as high of quality as the part I used, but results should still be fairly good.
Using S-Video to a TV would result in more "native" video than upconverting to VGA for display on a PC monitor. S-Video loses a little color info compared to the RGB colorspace, but not much.

i used the same rgb to ntsc converter on my time crisis 3 dx and it works better than the $400 namco one

Thanks for everyone's input. I think I will order the A-22 and see how it looks on a cheap TV.
It's cheap enough to take a gamble.
I will post my opinion on this forum when I see how it works. (Might be a while.)
This could be a cheap way to go for others wanting to do what I want, since most RGB to VGA converters that I have found on the net are over 100 bucks .
MonMotha, I would like to see the schematic of the one you built.
Edited for spelling..
MonMotha:
I don't have the schematic handy. It used the Analog Devices AD724, but I had problems getting the subcarrier oscillator to tune up properly when using the onboard oscillator, so I had to build an "outboard oscillator" to use with it. I eventually revised the design to use the AD725 which has no onboard oscillator, is easier to acquire, and has a chroma trap function for the composite output, but I never fabricated that revised design.
The design also had an input buffer so that I could more easily control the input impedance to avoid dimming the cabinet monitor when things were connected in parallel since that's how I designed it to be used. RGB input was also on an HD15 connector, and the board had a local regulator to improve the power quality. The ArcadeMVS/Wei-Ya (looks to be the exact same thing) design doesn't have these features.
If you were looking for something you could build yourself, my design was not buildable on a protoboard. I had a PCB made. That alone would put you well above the price of the arcademvs part.

Bumped for an update.
I decided to order the product # A24.
I have a few CRT monitors lying around, and I figured I might as well use one of them, instead of buying a TV.
Looks like this card will do the trick.
Here is the link:

Scroll down the page until you get to item A24.
I was a little scared to order, since it is in China and you have to paypal your payment to the guy, no order form on the website.
I emailed him to make sure the board was still in stock.
They answered my email pretty quick, and also said that the price on the website is wrong. Website says 49.99 US dollars for one. He said the actual price is 39.99 US dollars, so that made me feel good.
39.99+12 S&H+1 insurance, total 52.99. Not a bad price if this board does what it claims.
I went ahead and ordered one. I will post again with my opinion on it when I receive it.
I might do an all out review on it.
