Been like 15 years since I messed with it. It wasn't worth it then, not worth it now. But if IIRC, it was just a Windows display setting, like multiple monitors today.

Mister can display the proper resolution for its arcade cores through s-video. I’m assuming groovymame can do so using the same adapter.
I can attempt it when I have some time and report back.

Yes, you could easily switch on svideo but it was 480i. Automatically. Every time.
He would not need groovymame to accomplish that. Just an old graphics card and old drivers.

S-video is a mystery to me still. It had the jumpy lines and dot crawl of composite until I acquired a Japanese Panasonic with a 240p switch.
Most of the nuances of “what I thought” was inherent to Svideo went away when I enabled the 240p switch on the device. There was still a bit of rainbow color banding but the image was solid and full of scanline.
I would love to know if you can apply a similar progressive image off of RGB converter sources somehow..
It’s still single channel chroma over a separate luma channel that is similar to Rgb’s seperate luma output.

There’s a few of these types around. On mister you have to adjust the sync-on-green and something else in the .ini.
There are specific s-video cores that some use, I do not and it works great. I’ve heard the actual composite connection is bad though.
Been following this for a minute. Thinking of just moving away from my Mistercade setups in the Mini Cute and NAC and trying to go the mini PC 15hz route.
I have two things I need to know about:
1. Can you have this setup without GroovyMame? I'd significantly prefer using Launchbox as I'm super comfy and familiar with it.
2. If yes to 1, is the investment in a J-Pac with ArcadeVGA card going to be enough or will CRTEmu still be needed?
If I'm missing key steps or info, please educate. I know I want a mini PC 15hz build, I'm just not feeling GroovyMame's aesthetic. If 15 hz in a Mini Cute and NAC requires GroovyMame, perhaps I'll reassess. Thanks!

Maybe you can try this, 15Khz computer connected to arcade.Work like
J-PAC Ultimarc Has Audio AMP.It's available at AliExpress for only $67 including shipping.The name of aliexpress is SQ ARCADE.
Launchbox is just a front end. Launchbox launches different emulators and games. GroovyMAME is a fork of emulator MAME. Basically, an emulator that you launch with Launchbox.
To answer your question, yes you can. But it is better to setup GroovyMAME to work with Launchbox.
ArcadeVGA is antiquated at this point. Also, from an expense perspective, not feasible. J-Pac is also been passed by in lieu of other solutions. For one, there is no audio amp on J-Pac and secondly, the video amp on J-Pac sucks (IMO).
What you should do instead is to pick up a discreet AMD Radeon HD5000 series or higher (not lower) video card ($10 used with a DVI/VGA dongle or with VGA output). If all you plan to do is run MAME, then get the lowest model in the Radeon series that can run in your PC. MAME is all emulated via the CPU, the GPU has no part in it. Only get a beefier card if you are running other emulators or launching other games using Launchbox.
Send me a test unit and I'll review it. If your product sucks though, I won't be kind. Also, I already see some issues with your connection options.

What is it?
Send me a unit. When I get my hands on it, we can discuss it privately.
Not trying to get something for free. I have a bunch of JAMMAizers. I do see something interesting on there and if it is what I think it is, you might just have something on your hands here.
Also, I can't find your unit on AliExpress. Provide a link.

Can someone post a direct link to that jpac clone with built in amp?
I could never understand why ultimarc never released a version with an amp. I asked Andy from ultimarc years ago why not as there is 12v on the jamma edge. He said "ultimarc products don’t draw power from the JAMMA power supply". Why not? All my official jpacs are frankenstein with the amp power soldered to pins F/6 on the jpac. Likewise stereo soldered to pins 10/L

JammaSD. It is OOS everywhere.
So get the low profile Radeon card and have the VGA/DVI dongle, pop that in a small form factor PC. Small, 60 dollars worth of investment. From there, I do what? Add Windows 7, CRT Emu and GroovyMame and then add the Launchbox front end at the very end? Somewhere in there, I get it hooked up to the Mini Cute or NAC monitor.
Before you do any of this, you should get an LCD monitor that can display a 15khz signal, even if just barely. You don't want to damage your arcade monitors by feeding it a 31khz signal.
Once you have that, use GroovyTime. You'll need a JAMMA interface too.

Found the aliexpress version of the pc to jamma card (jpac clone with amp)
https://www.aliexpress.com/item/1005004604877106.html
what's the input lag like on this (and jammaASD) compared to jpac (0 lag)? Do they output safe sync signals?
