Is there already a psx emulator with customizable dithering patterns? I just added 16x16 blue noise dithering in lr-beetle-psx software renderer. Result looks quite interesting and could be used to optimize dithering in Silent Hill.
Original 4x4 Bayer
16x16 Blue Noise
Is dithering implementation of most emus wrong? If i shift original bayer dither matrix for rgb color components to minimize luminace pattering result looks also much better.
R= x,y G= x+1, y+2 B= x+2, y+1
Can you make a shader we can use on Windows or other platforms?
PS1 dithering is very primitive, even accounting for the hardware and time period. Most people just jump straight to 32-bit color via hardware renderers, but I do like the idea of just improving the existing dithering implementation.
If you ifdefed that to HAVE_HW (or whatever the compiler flag is to trigger the beetle-psx-hw build cycle) and sent a PR, I imagine we’d merge it.
@GemaH There is a blue noise dithering shader Blue noise dithering shader. Playstation uses dithering to hide color banding. Shader should be used if 32Bit rendering is enabled.
@hunterk i will take a look if i can add a core option.
