Adapter help

[Tytris]

Hey guys,

I bought a new Jamma harness as I am doing some swaps on my 246 cabinet, but to add my CPS2 board but it doesnt support VGA like my 246 does. My question is would anyone happen to have an adapter that would work or be able to suggest a way to hook the 2 pieces up .... Radio Shack here is a bust... TIA

Most JAMMA harnesses will have a long white 10-pin connector (similar to the one in your picture) that plugs into the arcade monitor for the video signal, that "VGA Adatper" is made so you plug it into that instead and then run a VGA cable to your monitor. This is not at all standard though which is likely why the connector on your harness is different than the one on the VGA adapter. you'll need to crimp on the proper type connector.

just for reference that adapter wont make the game work on a VGA monitor, it just changes the connector type from the connector type found on the end of most JAMMA harnesses to a VGA connector.

you monitor will still need to support a 15KHz RGB signal.

EDIT:
the Pinout on your VGA adapter should be
Red|Green|Blue|Ground|V+|H+|blank|V-|H-

in most cases you'll want to hook your "sync" wire to the H- and ignore the rest of the sync pins.

Would there be a way to make just an individual bridge wire ? I contacted the company that made the video adapter, however I was given the default "chain letter" type of comment that they don't support Chinese jamma harnesses the sad thing is if i could find a way to split the connector it would connect fine......

I don't know what monitor you have in the 246 cab... But my guess would be that it only does VGA/31k.
If that is correct, you will need a scaler to change the 15k video from CPS2 into 31k to display on the monitor.

Scalers range dramatically in quality and price and and overall compatibility.

The most compatible scaler I've found to be the xRGB Mini, it has about 16ms of lag tho.

The fastest scaler I've found to be the OSSC, it however has some compatibility issues.

The only scaler built specifically for arcade boards is the Taito PCB included in the Vewlix JAMMA kit, it's comparable to the OSSC in speed but the compatibility is even worse.

The GBS-8200 is the cheapest scaler I've ever seen, has horrific lag, with poor compatibility, also easily the worst scaler I've used (I gave mine to Warejag for free vs just tossing it in the trash).

A few more notes about the above...
Production of the xRGB mini has ended, we suspect it is being replaced by an updated version but no official word (this could be the last chance to buy one).
The OSSC continues to make minor improvements with every firmware release, this is going to be the one to watch over the next year (and my strongest recommendation for a future proof device).
Taito is still offering the JAMMA kit via OVS parts direct, however it seems they no longer keep it stocked, as the lead time is always 45 days (I'm afraid production could just end without any advanced notice so again this could be the last chance to buy one).
I would never recommend anyone get a GBS, I felt bad even giving it away (might have been more fun to make a Youtube video of it getting set on fire).

Haha! Yea no way in hell that is going to display CPS2 (without a scaler).

Also because it's a computer monitor (aka no built in speakers or HDMI > 3.5mm audio passthru) I wouldn't recommend the xRGB mini for use with it.
Mini sends the audio over HDMI, you can adapt HDMI into DVI easily, but not easily preserving the audio (then again CPS2 spits out its own audio via RCA so that may not be a concern).

Thrifting you say? Check out this monitor I got for my Vewlix Capcom...

It's 32" and was 1,400$ (approximately, some shipping and currency exchange fees make it hard to nail down the exact value).

if i could find a way to split the connector it would connect fine

use a pair of wire snips like these:


or if you don't have those, use a box cutter to deepen the groove on either side over and over again until it's weak enough to snap by hand.

But yeah, as Jassin pointed out, that monitor wont display games on the CPS2.

The CPS2 uses a "15KHz" resolution (that means the pixels are drawn on the screen at a rate of 15000 times per second). Most LCDs don't support anything below 31KHz. But there are a few exceptions: NON-CRT Displays that support 25K resolutions

Honestly this is a big part of why CRTs are still king for classic arcade games.

maybe hunt down a tri-sync monitor and a HAS supergun.. Here is a picture of my "arcade" setup.. But again another 15khz cab might be an easier solution if you have the space

Is the GBS-8200 that bad? I was thinking about picking one up, I'm in two minds now. Has anyone tried the wei-ya avc-011, apparently it doesn't lag but has compatibility issues.
