Oh no, Retro-Nerd, I didn't want to ignore, to depreciate your valuable help! Was my fault, I only wanted to give thanks at the thread end, because I thought it was more logical.
Thank you for your help and comprehension, always. |

It's not so much the glare or the curvature (I had a perfectly flat screen for my Amiga) but rather the RF/PAL colour bleed, which is a completely different beast to the colour bloom we're seeing in other shaders. I have yet to see any shaders that look correct for a PAL TV, they all look like arcade CRT monitors.

I do have several different CRT monitors and TV's, but even those all look different because of their different mask technologies, then add in the possibility of using RF instead of RGB, then add gamma, contrast, brightness etc configuration and you have a million different possible looks to one and the same input signal. So yeah, there's a good reason why so many people have a different opinion of what looks "correct" for them when it comes to CRT.. Queue the long list of configurable parameters in shaders |

http://eab.abime.net/showthread.php?t=87030&page=10 Unfortunately it's a multipass shader and depends on calculated masks, so i'm not able to create one for WinUAE. Maybe you like it. |

Do any of the shader gurus here understand how the NES and SNES classic performs the border/overlay color cycling animation type effect? I have read Nintendo uses standard png files and a custom shader, but don't know enough about it to really know. It would be cool to integrate this ability with Retroarch on other platforms than the NES/SNES Classic.

guest.r, is there any way you can create a shader to simulate slot mask type TVs for us? I've tried the masks of the links below but for some reason they do not look nice on my computer when I use them with your other shaders.
My CRT TV that had the most beautiful image was of this type and I used it with my Amiga 500 that I no longer have. I use a computer with Intel 4400 chipset and FullHD LED TV. I'm not sure if this is influencing the result. But surely the result would be much better on a 4K UltraHD TV. http://eab.abime.net/showpost.php?p=...3&postcount=62 http://eab.abime.net/showpost.php?p=...0&postcount=64 Last edited by Leandro Jardim; 24 June 2018 at 02:31. |

Shader generated masks are not possible to implement yet with WinUAE due two reasons.
First is the lack of input (uniform) variables for original and output sizes afaik and the second is that exact scaling to output resolution is required. Latter is very hard to do, since there is zillions of scaling options and especially smart overlays make it even harder. The only help i can offer with masks was the modified _winuae.fx shader under d3d9 which applies them in gamma space. I think even a shader mask would look preety the same as a png one though. |

This is a good one too, runs very fast even on old Geforce FX 5200, Radeon 9200 etc.

Why not, i tested it and it looks very good with simpler gfx. games like rainbow islands, Bubble Bobble etc. Everywhere else is a matter of taste.
Would port it sooner but have been busy with rep grinding. |

Took a look at 2 pass GDAPT (anti)dithering shader and managed to port it to WinUAE. Good news is it's almost as good as MDAPT (5 pass, mission impossible here) when clearing large surfaces, still a bit inferior overall.
With a D3D11 config you can use it as a standalone shader, best with integer scaling. Another good news is with D3D9, you can stack effects. Just put GDAPT under the -1 pass and desired shader under 0. There is another "aggressive" version, which smears text and similar. Use at own preference. |

You can try to put the GDAPT under the "-1" pass and the CRT-Guest-Glow-Fast-Lo-Res.fx under the "1" pass. I think this should work.
D3D9 only for now i guess. It's not possible to merge it under D3D11 for now, since wokingsampler is not supported. |

Np. Dithering didn't consider emulation and sharp displays.
Anyway, here is the gamma space version of the GDAPT shader, you can use it as the dafault version i guess. |

I found the previously posted CRT-Scanline a bit boring, so i developed a new "main" function, which is better. You can get better looking scanlines with the new version now (it's customisable).
3x setting is recommended, should be fast enough. Edit: New, improved version. Much nicer IMO. Last edited by guest.r; 06 November 2018 at 14:55. |
