The history of the creation of this shader preset

for correct viewing OLEDTV
BFI ON ( BLACK FRAME INSERTION )
my shader compensates for luminosity peaks, and this is taken into account,
and it's the best way to get close to the motion movement of a sony tv crt
CONTRAST 70 OR 80
LUMINOSITE 70 OR 80
COLOR 50 ( MODE NORMAL NOT HOT1 OR HOT2 ETC)
IMAGE ADVANCE COLOR REC2020 OR NATIVE COLOR ( NOT REC709)
IN REC 709 BLUE AND RED WILL NOT MATCH THE SONY CRT KVB APERTURE

SHADER CRT APERTURE GRILL TRINITRON FOR OLED4K
REFERENCE MODEL my crt sony trinitron kvb aperture
Core beetle psx hw ( vulkan)

native 1X resolution, no enhancement, no antialiasing, no geometric correction, polygonal with pgxp, no 2d filtering, everything is original, even the dithering is native in the core.
the goal is to make the shader work only without any enhancement help, you can't display a playstation game with precalculated images, 2d sprites, etc.. any enhancement attempt will take you away from a native 240p rendering on a consumer tv crt.
it will look like an old uppscale game in blurry 4k and far from reality.
so there are enough shaders like that for those who are looking to multiply the resolution by 8 or 10 with 16x anistropic and antialiasing.... etc...

here nothing of that only the shader filters a raw image, with a mask aperture, and triads of phosphors, like a sony aperture crt would. no visible scanline...
no dark image, good contrast, clean and well defined sprites, no loss of details, that's what this shader brings compared to simple scanline that will disappear as soon as you make a vertical movement... in games like zelda?? your scanline become useless on a modern screen. ... if your scanline disappear? you end up with a raw uppscale image in 4k which is nothing like a crt, which has a low native resolution of 240p 320X240, so each pixel is in its place on crt and in motion your image remains filtered.
Here is my opinion which commits only me.
I emulate machines for a long time and I'm lucky to still have my game consoles and my crt to see them compared with my shader etc.....
this is an advantage, because as soon as you look at the native image of the crt, you can easily see what is wrong with the shader.... loss of contrast, brightness, dark and saturated colors, bad gamma and gamut etc... here is 99% of the default preset of retroarch....
so I got a 1080p plasma and emulated it with retroarch
and now in 4k oled because better resolution = more accurate shader mask and I see it.
we are also talking about 8k... more accurate mask aperture shader.

so my goal is just to find my games nice on a modern 4k oled screen that's all
because the shader i try combines the flaws of a dozen crt and compiles them into one shader, you end up with remanence, motion blur, haliation, color problems etc...because people in their memory it's like that...royal crt looks nothing like my crt, or 99% of the consumer crt people had...
I never played with a sony bvm pro as a child that I know of.....
so that's why I started to make my shader preset to all those who are disappointed with the retro rendering on their oled4k screen and all the shaders present in retroarch
WARNING I don't criticize the shader creators I thank them with all my heart, but I'm honest no default preset rendering in retroarch pleases me....
so yes you can do what you want with shaders modify what you want...
but when i got the oled what is the retroarch shader for TV4k OLED NO RGB? BUT WRGB
0 OR 1 or 2 shader? kurozomi crt royale and lottes???FOR 4K WRGB? I don't know...
so there is a lack of retroarch that I'm trying to fill.
SORRY FOR MY ENGLISH I AM FRENCH
thanks a lot
