Shader crt-pi.glsl Raspberry Pi4 Recalbox 7
-
Hi. I managed to run overlays and shader crt-pi.glsl into recalbox 7 on raspberry pi 3b+. But the same conditions do not allow the shader to work on Raspberry Pi 4. Will a new working shader for Raspberry Pi 4 be written, deforming the picture with the stylistics like the old picture tube? Or can the old one also work with the new gpu under certain conditions?

7.0.1 - The problem is still there!
-
Still the same with 7.1.1
The zfast crt shaders arent bad, but i like the old crt-pi shaders much more.

hello
please go to/share_int/
Downloadshaders.tar.xz
unzip archive
move all files in/share/shaders
you need to erase files inside.and try again.

Ive done everything like you said, but no difference.
Ive flashed a new 7.1.1 image to a second sdcard, but it is just the same
crt-pi
crt-pi-barrel
crt-pi-mask...still broke
-
Do you have the file
/share/shaders/lr/crt-pi/crt-pi.glsl? If not, you need to do again what @acris said above. -
-
@Zemus it should work in that case. If it still doesn't work, maybe try to restart?
-
It simply doesnt.
Like i said. If its a fresh install or my upgraded system...it doesnt work

OK...
with this shader as source, i was able to fix the crt-pi shader for RPI4
https://github.com/libretro/glsl-shaders/blob/master/crt/shaders/crt-pi.glsl
I tweaked some values , so that the shader looks as close as the one on RPI3 (reduce moire effect, deactivate mask for real colour)
I didnt found a source for the barrel and mask shader (maybe special recalbox shaders?), so this was the only one i could fix for now.
Just copy the crt-pi.glsl file to /recalbox/share/shaders/lr/crt-pi
