I’m using OpenEmu on Mac instead of RetroArch, so not everything seems to work / work as intended. But, on the whole what I’m trying to do is have a series of clean scanline (or lcd grid for handheld) filters like you might find on official mini consoles/Analogue HD consoles/UltraHDMI adapters. (so, outside of this topic - I am open to ideas and suggestions.)
For scanlines, I’ve been using Yeetron from Sonic Mania. Whenever I’ve tried to stack Pixellate before it to ensure pixels are first correctly shaped, the pixellate effect would be absent. Eventually, I got it to half show-up like so:
shaders = 5 shader0 = ../Sources/Slang/stock.slang filter_linear0 = false scale_type0 = source scale0 = 1.0 shader1 = ../Sources/Slang/misc/ntsc-colors.slang filter_linear1 = false scale_type1 = source scale1 = 1.0 shader2 = ../Sources/Slang/crt/shaders/snes-hires-blend.slang filter_linear2 = false scale_type2 = source scale2 = 1.0 shader3 = ../Sources/Slang/interpolation/shaders/pixellate.slang filter_linear3 = false scale_type_3 = source scale3 = 1.0 scale_type_x3 = viewport scale_x3 = 1.0 scale_type_y3 = source scale_y3 = 1.0 shader4 = ../Sources/Slang/crt/shaders/yeetron.slang filter_linear4 = false scale_type_4 = source scale4 = 1.0 parameters="INTERPOLATE_IN_LINEAR_GAMMA; NTSC Intensity" INTERPOLATE_IN_LINEAR_GAMMA = 0.0 "NTSC Intensity" = 0.0
That’s getting the effect to appear on the sides of a pixel, but not on the top and bottom (need to zoom in to see). How can I get the entire effect? I’m using Super Mario World’s title screen as a test. Mostly looking at the black pixels in the red S.
