Is it possible to emulate a crt on a high end oled?

Retro gaming is alot better looking on a crt and duckhunt need perfect timing, but with 500hz tv, timing shoul be no problem or is it the backlight that's to slow? 

 

A electron gun makes a line in 16,7 microseconds for a 1080p HD image. That doesn't sound that fast but I am not a tv neard.

the benefit of a CRT is that there is essentially zero input lag between the signal coming in and being displayed on screen.

 

things like duck hunt dont work on modern displays because they are extremely latency sensitive (basicly the target is displayed for exactly one frame, and the gun detects if it's aiming for the target during exactly that frame. and the platform can do that because how CRT's work)

 

the way to make duck hunt work is to rom hack and adjust for latency. the way to make retro games look better on modern displays, once again, is also to actually just implement a better scalign algorithm. modern displays can make retro games pop in ways the devs pretty much could only see on their most high end dev equipment.. it's just a matter of scaling the output correctly.

CRT screens are known for their near-zero latency, which is a big reason why games like Duck Hunt worked so well. Modern displays process signals differently, which makes syncing with the light gun more difficult.

Do you think latency is the only issue, or could it also be how CRTs handle signals and render images? And if we tried to emulate how the light gun interacts with the screen, would it change how we perceive the visuals? Could this bring us closer to the original experience, or create new challenges?

On PC, there are many shader options to make running retro gaming look like it is on a CRT. Given the low native resolution of games from decades ago, you can simulate the look of a CRT on a 4k display by adding simulated scan line and phosphor patterns, even phosphor decay response. I don't know if lower resolution screens can do it. I bought but never properly played FFVI as it looked a bit too retro for me. After a chance viewing of a video on YouTube about using such retro filters, I did try one out and it does look much nicer with it. 

 

I've not look at options in detail if you have an older console. I think some stand alone upscalers that convert to HDMI can also apply a CRT emulation filter.

 

Light guns are probably unworkable due to differences in how the TVs work. I don't know if anyone has tried to emulate that somehow but it would likely require a hardware solution.

there someone that got it working but dont really no the details

Well depends for what and to what degree. You need a fast OLED 240Hz+ for start. I hope we get a good option eventually.

There's thing being worked on:
