Hi Guys
Nearly at wits end with this issue. Trying to get shaders working (for NES in particular). I followed this helpful thread and configured all the retroarch.cfg files I could find with the following settings:
/opt/retropie/configs/all & /opt/retropie/emulators/RetroArch
– video_shader = “/opt/retropie/shader/*.glslp”
– video_shader_enable = true
– video_shader_dir = /opt/retropie/shader/
/opt/retropie/configs/nes
– video_shader = “/opt/retropie/shader/hq2x_phosphor.glslp”
– video_shader_enable = true
The issue is when I go to run a NES game I get the following error before the game fires up:
“Frontend supports RGB565 – will use that instead of XRGB1555”
“RetroArch [ERROR] :: Failed to load GLSL shader: /home/pi/RetroPie/shader/hq2x.glsl”
“RetroArch [ERROR] :: Failed to init sharer, falling back on stock.”
“RetroArch [ERROR] :: [GL]: Stock GLSL shaders will be used.
*I have also attached a pic for your reference (apologies for the shonty angle)
Looking at the error I assumed there would be a config file which is still telling RetroArch to look at a non-existent directory for a shader I dont want to use. I just cannot find it anywhere.
I did end up putting a shader directory including shaders into the “/home/pi/RetroPie/shader/hq2x.glsl” and this worked. However as mentioned this is not the shader I want to use. In fact I’m even fine with keeping the shader directory here if I could at least find where I can configure the reference to the shader used.
Any help would be much appreciated, thanks.
