I promised the person who was posting under my name months ago that I would post pictures of my cables and PVM when I had GroovyMAME and CRT_EMUdriver set up. I delivered on my promise. I'm done with this.

If the CRT thread feels that SquarePusher and his advice is what's wanted here instead of my presence and tutorial, I have no problem never talking about CRTs again. I can enjoy them for myself.

You guys win, I'm an idiot for doing what you've been unable to do. Enjoy discussing CRTs.

I'm sorry dude, but you just said that home consoles running DoDonPachi run it at 60 fps like RetroArch does rather than the correct 57 fps like my rig / the arcade does.

You just said that I'm wrong but said the exact same thing that I did. You'll feel better when you set something like this up yourself and will no longer feel the need to try to dismantle it.

RetroArch does not output Mortal Kombat at 54 Hz, my TV would default to PAL if it did. You're making things up. RetroArch can't play MK at all.

I think you've already arrived at a conclusion and are offering arguments to justify it rather than looking at what is objectively true. Windows XP is where input lag has been conquered. Linux is able to output custom refresh rates more readily than Windows. There is already a custom Linux distribution just for running GroovyUME/MAME, but it's full of input lag. You'd have to reinvent the wheel after already reinventing it.

If you have Linux skills and a high speed camera, you could test RetroArch's response times under custom resolutions and sync rates. Maybe it's killer at SNES emulation running bsnes or something.

People have made this point before but I'm not sure they know anything about MAME on Linux. The libraries it's built from introduce a minimum of 3 frames of input lag no matter what you do.

Linux is completely deprecated in the arcade emulation CRT community at this point due to the lag it will always introduce. Windows XP is the system on which zero input lag has been proven, equal measurements in lag to superguns.

But yeah, there aren't many arcade games that run at 60.000 Hz. There are some, and these feel good on RetroArch. Most arcade games, and console games too, require very precise custom refresh rates other than 60 Hz.

To eliminate input lag with Linux, you'd need to rewrite the whole of MAME. To eliminate input lag with Windows XP, you just need an ATI video card and Calamity's software...AND to enable the raw_input API in MAME, and use a proper keyboard encoder.

Here's the only one I have of the whole setup at the moment. Splatterhouse of course running at native resolution...this modeline fills the monitor quite well.

And now some scanline porn of Bad Dudes running at 256 x 240p and 57.392 Hz (target refresh: 57.392103 Hz). The black areas on the side will be adjusted using precise microsecond timings for the front and back porches, I already centered it doing this and just have to widen it a little now.

This is for the people who said that you can't get accurate sync rates without the use of special crystals. When you play R-Type using RetroArch on Wii, it runs at 60 frames per second. Because RetroArch's vsync runs the game at the output rate, this results in unplayable R-Type. It needs to run as close to 55.017606 Hz as possible, and be synced to this.

GroovyMAME's video output is heavily customized beyond SwitchRes...input lag can be completely eliminated with this setup. DoDonPachi runs at 57 Hz, it's unplayable on RetroArch. I move my stick though with this setup, the ship moves with it...I can feel the response. Anyway, here's R-Type's boot screen.

Hey folks. I want you all to know that my big talk about getting 15 Khz RGB signals out of your computer and to a monitor/TV, with accurate sync rates and resolutions, has come to fruition. You can all do this too, and it just takes a cheap old ATI video card and an RGB monitor or TV with component inputs (plus a transcoder for that).

I've made a rudimentary guide that I hope to update with more detail, but this is essentially the secret to perfect emulation. My sync rates are well within 1/1000th of a Hz for all games...the only one I've had problems with so far is BloodStorm because it runs at 384x256 but over 60 Hz (unlike R-Type's 55 Hz.) Just need to tweak my settings and see how high in horizontal frequency the PVM can go...I've gotten it up to 16.3 Khz so far.

Here's an early tutorial...check it out and the links in it and you'll see which video cards this works with. You might just have one lying around, even many AGP models will work perfectly.

Custom computer built. CRT_EMUdriver / VMMaker / ArcadeOSD / GroovyUME/MAME installed. 120 modelines generated. PVM attached, desktop 640x480i. Modes generted on the fly for all MAME games tested so far...vertical sync within 0.01-0.001 Hz for all games, synced to refresh so that it actually means something and isn't pleb syncing. Come at me now.

You can be at it for the palm time, I won't judge.

>>1000548 (You)
No.

You're at it for the fist time.

Down one road, you'll find mystery and false authority.

Down the other, more tangled path, you'll find wisdom, brought about by self-education.

I can hope for you, but I can't decide for you. Choose wisely. Don't just go at it again, and to thine own self always be true!

>>1000482
You just might be speaking from a position of true authority on this matter, but I'll let the mystery linger.

Unlike this gentleman, who is clearly speaking from a position of false authority:

>>1000467
more assumptions, more wasting of everyone's time

easy to confirm, hard to grasp, impossible to believe

>>1000451
*sigh*

you're at it again

>>1000438
Until you start to recognize the illusions under which you have been operating and the assumptions that you've been making to compensate for unseen inadequacies to everyone's detriment, I find it beneath me to recognize any of your accusations.

Someone, mayhaps thine own self, mentioned one item of particularly delicious interest. Intriguing, and quite relevant to emulation. I'll leave it to the group to identify and ponder.

>>1000431
No comedy is complete without the false authority of an adversary.

TV encoders are the cause of quite a few topics of interest in this thread. Mayhaps one should be studying a little bit more. Additional research should prove...interesting.

>>1000414
tis true, my fedora of many colors should be enough for all to recognize the truth. Don't hate, appreciate.

I'll say nothing of TV encoders. This is an exercise for the reader. Just don't expect me to wait for the class to catch up.

>>1000407
This guy's right. Thus endeth the lesson bitches.

*mic drop*
*strut off the stage euphorically*

>>1000397
Either way, what an idiot.

>>1000362
Part two of the lesson: figure it out. I may as well not post anything at all, you know.

I'm stupid and at it again

dis shit don't stop
