Hi,
I am trying to apply a GameBoy shader alike the HarlequinVG, but I didnt find a way to make it work…
I added this configs on /opt/retropie/configs/gb/retroarch.cfg:
video_shader = /opt/retropie/emulators/retroarch/shader/handheld/gameboy/gb-shader.glslp
video_shader_enable = true
video_smooth = false
but stills not working
