Need Help with ArcadeVGA and sync!

dpful · Post by **dpful** » Wed Apr 23, 2008 5:56 pm

The monitor says WG 1575859 near the bar code (I didn't see anything else).
It syncs up great with my Gradius IV PCB on it's med res setting (I don't know exactly what that means.. Medium resolution monitor, 25k, resolution ? )
But it won't sync to me arcade VGA card. I just bought it, it's the new vesion, it works great with my standard res monitor. The jumper for 15k 30k 25k deosn't seem to do anything when either monitor is plugged in. I've tried some different settings on the modes list (display control panel) including default refresh rate.

Please help, anybody- if I can't get this worked out, I'll have hundreds of pounds of extra garbage plus lots of wasted money.

the jumpers (on the JPAC?) are to block rates that don't match the jumper.

the arcadevga didn't always support 25khz, but the newest does.

Yeah, I've got the new one.

hi, the ultimarc page says it can display some resolutions with 25kHz on multisync monitors. don't think it can display all the resolutions on such a 25kHz screen. you may email andy from ultimarc, normally he answers fast.

How do I tell if I have the new one?
Does it support Sega System24 resolutions? Might need to buy one.

Sorry to hijack your thread, dpful.

The old one is shaped kind of like an L with two monitor chord sockets. The new one is a square with a huge heat sink on half of it and a monitor socket, s video socket, and new fangled digital monitor socket.

I wrote andy and he said I have to load up the tri-sync utility on his site (haven't got it to work yet, but I think I will), and then it will display med res stuff perfect (won't get a legible boot screen on the computer), but you can't use any other resolutions with it, so anything else will have to be resampled and stretched (which I don't mind). I've got a vert cab with a huge ass med res monitor I want to use for shmups mame cab. I don't mind the resampling.

That should be those med. resolution modes on an 25kHz screen. Resolution 488x384 and 512x384 are available in the driver, you just need the right screen.

For dpful,

Can you provide a pic of your newest ArcadeVGA card please?

At first glance, mine looks just like this one except the caps are silver and the heat sink extends to cover those chips that are near it in the pic

Here's a pic of the old one. The "L" shapes one I was talking about was a mistake (I was looking at some random card I had at my house and mistook it for my last arcadevga)

For dpful,

Ah, that's a cool pic of the latest ArcadeVGA card iteration. I only have the older 1st generation model myself. How much did it set you back may I ask?

I think it was around 80$

If you havn't been to his site recently, you should browse. It seems like he's always revising and improving his stuff.
I am so impressed with the company- if you write Andy about any probs, he writes back about as close to immediately as I've ever seen.

so this AVGA is better for emulation purposes than a new geforce card or anything like that?

wrdaniel · Post by **wrdaniel** » Fri May 02, 2008 10:00 pm

the avga card is an easy way to get low/medium resolution modes on arcade monitors / rgb screens that run with 15 or 25 kHz.

Somewhat on the subject, can a 15/24khz display manage 640 interlaced at all? I know the ArcadeVGA card says it'll run stuff at 640x480 on a 15khz, but I'm somewhat skeptical if the results would be decent enough to play with.

it flickers pretty bad on 15khz.

YOu mean 480 interlaced? What are you wanting to play? If the game is intended for 240p or 480i (and you have a proper monitor) it looks fantastic.

Yeah 480i is what I meant. I wasn't thinking games designed for interlaced though, I was thinking games that run natively in 640x480 resolution on the PC trying to run at 480i. Something like trying to run Akatsuki Blitzkampf on it or things like that.

GaijinPunch · Post by **GaijinPunch** » Sun May 04, 2008 4:01 pm

Are Naomi carts emulated? AFAIK that game runs at 480p... which the AVGA supports. The latest update for the older card (and I assume newer one) supports 480p, which my desktop now runs in. The emulator decides when to change the frequency.
