Does anyone have experience with this thing? My results with component output do not match the quality output from other people online using an equivalent vga output. I think the problem is this thing implying a sharpening filter.

VR doesn't know much about this thing

Darn. Neither does the internet. There was a guy here a couple of weeks ago who bought one and said that he was going to post the results when it arrived.

I guess I'll have to go the expensive route and buy scart to component to play mame authentically.

If I were putting VGA into a project enclosure that had component outputs and having trouble I'd probably try using crt_emudriver, soft15khz or even the defauly drivers to feed it a 15khzsignal. That's assuming I had a VGA cable and a DC power supply plugged into it. Maybe 12v? 5v? I'd probably start with 5, both tip polarities then move up to 12... Maybe at 500mA to start. I mean, I've never been the most cautious about plugging my jacks into mystery boxes but better safe than sorry amirite?

>crt_emudriver
I have tried that on windows 7 and 10. I even tried GroovyArcade. I still get a picture that is scaled too sharply to be considered 15khz. It resembles the 31khz pc monitor that I have.

I'm no electronic engineer but the ebay page does list information about discrepancies between voltages.

Here is the page

Yeah, I have a lot of experience with electronics hobby boxes. What do you want to know about them. kek

Even though I've played a lot of MvC I'm not sure if that's the way Chun-Li is supposed to look in some mid-move but at a glance it looks like heinous frame splitting - and his CRT is overscanning like a motherfucker too.

From the description though it seems like it should do what it's supposed to do assuming it gets the right frequency from the computer side.

Post a pic of what you mean by "too sharp to be considered 15khz". On a high phosphor persistence display like an SDCRT there shouldn't be noticeable flicker at 15khz, that's how they were designed.

It's probably rolling shutter because he's using a shit camera and doesn't know enough to circumvent it.

The 1st is component a 2560 superwide resolution using crt_emu. The second is composite output from the Raspberry Pi at 240p (720 x 480).

WAT?

>>4193218
This is just the natural color blending that comes from composite, literally the compositing of all the colors into one signal

>>4193207
This is how the RGB output of a real Neo Geo would look. If you want it to blend just tank the sharpness setting on your CRT and maybe drop the brightness a bit and fiddle with contrast.

Still wondering if the scart to component one is anygood. I might bite the bullet and make a unlisted video for you guys. Since I happened upon a component capture card at goodwil.

>> No.4194316

>>4193280
Maybe I should find a vga to s-video output because the dithering is too sharp for my taste.

I could be wrong. I suppose without scaling vertically, there is no scaling artifacts Therefore, the dithering is super sharp. In addition, Castlevania and other smaller sprites look the same between connections and systems.

But there are some arcade videos I've seen that do not match the sharpness of what I'm seeing when emulating. They have a softer picture.

RGBHV converted to YPbPr or native output?

>composite output from the Raspberry Pi at 240p (720 x 480).
That sounds like 480p with overlaid scanlines to me i.e 31khz. How do you output this over composite from RPi?

>> No.4194516

>>4194316
if you're talking about NES castlvania and compare it to Neogeo and CPS games, well it's kinda normal, they have a higher horizontal res (50% more for CPS). HDCRT TVs (what you're using I suppose) also are sharper than your average arcade monitor.
And as said earlier your sharpness is probably way too high.

>>4194340
RGBHV converted to YPbPr at 2560 x 240p. I have also tried this same setup using native resolution. However, native resolution is more smooth in comparison.

The composite output is using the native 3.5mm jack from the Raspberry Pi. The Raspberry Pi has 240p limitations because of the frame buffer. So the actual width is always 720 x 480 but with every other line blacked out. The clarity of the composite is more akin to s-video but still has dot crawl.
