Would it be hypothetically possible for an extremely powerful computer to take in an analog video signal, RGB-SCART or Component or something, and to put out an image like the one on the left?
I know the one on the right is possible with the OSSC, but what about something like the left? Obviously it would need to be 8K or something

it's just what what a normal computer with a graphics card can do.
my 5 year old chromebook that crashes trying to open gmail can do it. try yours

Certainly, but what about a lagless solution like the OSSC?

[Anonymous No.7424846]

>>7424838
and if you insisted on starting from an analog signal that's nothing to do with computer power you just need some analog-to-digital sampler hardware either way. you can't plug the rgb cables into a usb port, can you

An 8K OLED could probably simulate the phosphor density and glow of an SD CRT and fake the scanlines for a believable image. A fast enough scaler could probably make it all 99% effective rendering CRTs practically obsolete. The 1% left over is lightguns. The only way to make those work again would be if in addition to the above the display can simulate the raster scan of an electron gun by rapidly toggling on and off each individual LED in sequence at the 15hz of an SD CRT rather than the typical sample and hold method. But I'm not sure any OLED display can operate at that speed.

I feel like there would need to be a totally different kind of display technology with some much more advanced processors in the TV for light guns to ever work out

i don't think you need a powerful pc to pull it off, but you can already do that, or get pretty close to it.

Yes, it's possible.

No need for an extremely powerful computer for that. Just google groovymame and/or 15khz graphic card.

>extremely powerful computer
its not an issue with logic, its an issue witht he physical makeup of lcd screens. Crt's look that way because thats what the physical screen looks like. Someone would have to build an lcd that looks similar, or have such a high rest that you could mimic that. But that would be way above 8k. My advice: crtemudriver+groovymame and other emulators on a consumer crt, you'll probably need to convert rgbhv (vga) to composite/component or whatever

Maybe it's because it's 1080p instead of like 8k or something but the fact that you can't see the RGB colors really hurts the look

[Anonymous No.7426657]

>>7424817
also, OP should try making overlays, I know mame uses them, and I believe retro arch has options to use them as well. So with a 4k screen you can use ms paint to make your own overlays that divide 4k res. into something similar to 240p. So 2160/240=9. So use a 9x9 pixel block on paint using transparent reds greens and blues and gray for scanline areas and blend it all together, then just load in mame and it will spread it evenly across the screen, you can really tailor it to your liking

Eh, I'm happy with the shader I'm using, dr-venom + composite signal (since this is what I used to play on). Now if I could set up my own tube it'd be brilliant.

Yes. That's exactly what the Classic Tetris World Championship team do to make a regular composite NES signal look like this on the broadcast:

I can't remember the dude's name but the techy behind the visuals developed his own upscaling/cleaning algorithm.

I can't believe Americans treat the NES Tetris as the definitive version and not the based ZX Spectrum Tetris.

My resolution is too shit to see it but CRT-royale actually emulates RGB phosphors if you put a high enough res.

It's so weird that this is one of the only CRT filters I've seen that replicates the vertical scan lines.
Most of them only do horizontal but I find the vertical ones more noticeable.

You can already do it in retroarch you just need 4k+ screen. This is on 1440p.

When you understand the difference between how a CRT functions and how an LCD functions you will come to the realization that there is no recreating that technology with widespread modern solutions. When you can comprehend the following statement you can fully understand the facets and all the ramifications of it, only then will you realize the truth:
CRTs operate in a 3D space, LCDs in a 2D space.

People are just stupid and keep trying to make garbage like Aimtrak and Sinden guns that work without sensor bars, when even arcades almost universally switched over to using sensor-based lightguns around 2000 (and Sega was doing it before). The main reason the wii sensor bar is so shoddy is because it's single-point. If you could get two or three of them working together to judge the position more accurately, you'd probably have a near-perfect light gun setup.

[Anonymous No.7428150]

>>7424884
microLED will be able to. Just make convex screens paired with a powerful enough graphics and you just made CRTs obsolete even for light gun games. I still want a flyback for that powered CRT sound.

>CRTs operate in a 3D space, LCDs in a 2D space
Just because something is flatter doesn’t make it 2D anon
The difference is CRT is self emissive light and LCD’s are not
Which is also why OLED look as good as they do as well

GUN4IR works fine, you just don't hear people talk about it because it's an open-source DIY thing, so there are no people who shelled out money for one and brag about it in an attempt to justify their purchase, like with Aimtrek or Sinden. It works the same way as the wiimote or Aimtrek, except it has a second set of sensors on the bottom of the screen like arcade games have, so it's way, way better at judging the position of your gun. It has only 4ms of lag, which is even faster than trying to play House of the Dead on the original NAOMI hardware.

Full displays are unlikely but I wouldn't be surprised if there's eventually custom PCBs that can be used to mod a TV's internals and drive the display as needed. Though I don't think a fixed pixel display can replicate a raster scan without an absurd amount of current.

[Anonymous No.7431585]

How many milliseconds would it have to apply the post processing for it to be considered lagless? On an 8k display mind you
