Hi all. I'm lacking some computer knowledge to comprehend the explanation quoted below (on how to add a different filter), written by Tmnt4242. I am using Retroarch on the NES Classic to play snes-, megadrive- and some nes games (that don't work too well on the stock emulator). The retro-v2 shader (combined with bilinear filtering) makes the games look a lot better (imo), but it doesn't really look like a proper crt effect. The scanline.glsl does look great, but for some reason on all games you see some vertical lines coming through on the right side of the screen (covering about 1/4th of the screen). So I wanted to try out crt-nes-mini.glsl, but I'm guessing there isn't an easier way than the explanation below, for computer dummies like me?
''Easy guide to using the crt-nes-mini.glsl shader as the default shader for all emulators in retroarch and having it auto enable/disable when switching between the 3 shader menu options on the nes mini.
Note: you will need to use clovershell command lines
1)Open a Command Prompt and navigate to your clovershell
Run --> Cmd ---> cd "clovershell location"
2) Download retroarch-clover file using the command line
clovershell pull "/bin/retroarch-clover" retroarch-clover
3) Open retroarch-clover and remove lines 56 and 57
Allow scanlines only for simple systems
[ "$allow_crt" == "1" ] || crt=0
4) Upload to file to nes mini via clover-shell command:
clovershell push retroarch-clover "/bin/retroarch-clover"
5) Download the original scanline.glsl file using command line:
clovershell pull "/etc/libretro/shaders/scanline.glsl" scanline.glsl
6) Open scanline.glsl and copy code from crt-nes-mini.glsl to files and save
Note: You are going to copy hizzlekizzle's raw code from
https://raw.githubusercontent.com/hizzlekizzle/glsl-shaders/master/crt/shaders/crt-nes-mini.glsl to the scanline.glsl file
7) Upload scanline.glsl to nes mini using command line:
clovershell push scanline.glsl "/etc/libretro/shaders/scanline.glsl"
8) Change Crop Overscan Option in Videos (Fixes Spacing) Open Retroarch Options --> Settings --> Videos --> Crop Overscan (Reload): ON''
