glsl-shaders VS RetroArch

Those are the Cg shaders. I think the mini/classics use the glsl shaders, which are located at: https://github.com/libretro/glsl-shaders

I'm trying to get this same scaling setup into MPV to use with video. I have everything setup perfect except the nearest-neighbor prescale, and the original retroarch glsl shader(https://github.com/libretro/glsl-shaders/blob/master/interpolation/shaders/sharp-bilinear.glsl) doesn't work in MPV. Anyone have any ideas?

Are you talkiing about this CRT Royale shader? If so, it comes from the Libretro project, not ReShade, and it's available in standard GLSL format here: https://github.com/libretro/glsl-shaders/tree/master/crt

There is a zip file at this place for a lot of glsl shaders https://github.com/libretro/glsl-shaders

If you use picom as a compositor you can write glsl shaders, there is some work being done twords doing full out CRT emulation at a desktop rendering level, I found the repo below[1], but on my monitor the shader does this distortion at the bottom so I think it could be improved slightly. I'd really like to see someone get the glsl shaders from libretro[2] working with picom.(which the project in OP did) if any GL wizards reading this have any advice I'd be eternally greatful

I've had this memcard file since the good ol' ePSXe days, hence the disparity in the player name at some point. I thought recording a video made more sense than a bunch of screenshots. I am using the crtsim shader preset for RetroArch if anyone's interested, has a nice subpixel matrix effect and brief phosphor image retention

You could try hosting the web version of Retroarch on your server, and use this but I don't think what you're looking for exists

Hi all Ive come across this github feature request from the project https://github.com/libretro/RetroArch/issues/8124

Thanks to the amazing people at EmulatorJS and Libretro for making this all possible.

It wasn't originally developed for BSNES. It seems to go as far back as 2018 with a patch by Nitsuja for a TAS geared Gens fork then submitted to RA by Dwedit in 2018

It's a pretty hairy topic once you get into the details but you can read through this issue thread to get up to speed: https://github.com/libretro/RetroArch/issues/6875

So this is the issue: https://github.com/libretro/RetroArch/pull/13913
