Shader set for all systems

Sanctus

I would like to change the default Curvature Shader with the designated crt-pi-curvature.glslp (in Retroarch).

After too much tests i strongly prefer the crt-easymode.glslp.

I wonder if someone can tell me where is the file (in the Batocera 5.24 file structure) where we can change the line that says that Batocera Curvature Shader is using the crt-pi-curvature.glslp.

Or, if we can add a default new one, since I have not been able to make RetroArch to save my default shader for all systems.

Thanks for your time!

The shader preset configs are located in /usr/share/batocera/shaders/configs.
If I understand correctly you want to replace the "crt-pi-curvature.glslp" shader from the CURVATURE preset with "crt-easymode.glslp". You can do that by editing /usr/share/batocera/shaders/configs/curvature/rendering-defaults.yml and do the replacement in that file. Beware: you need to remove the .glslp extension (just as it is now).
And to save it permanently, you need to do a batocera-save-overlay command after the edition, as usual.

lbrpdx a huge thanks for your fast response!
I have just one doubt since I am a newbie in Batocera (even though I have some background in informatics), I don't know the right steps to save it permanently with that command you gave.
(I am accessing the Batocera folder structure by pressing the F1 inside Batocera, are you suggesting to access Batocera by ssh to do that command?)

Batocera OS is provided as a read-only firmware. All the additional user data is stored in a writable /userdata/ partition. If you make any change outside of /userdata/, it will be lost on next reboot, unless you use the batocera-save-overlay command, which adds an "overlay" of your modifications on top of the read-only system.

More information on the wiki: https://batocera.org/wiki/doku.php?id=en:modify_the_system_while_it_s_running and https://batocera.org/wiki/doku.php?id=en:batocera.linux_architecture for more details on the system itself.

You can use any batocera-* or shell command from a SSH connection or from the terminal (F1, then F4 to launch an xterm).

You can set per system shader in batocera.conf file in system folder using ssh or simpler edit it with your prefered text editor using the network share.

For exemple i want to use the crt royale fake bloom intel for snes system, you can add this line in your batocera.conf

snes-renderer.shader=/crt/crt-royale-fake-bloom-intel

Spacebar this proved to be the easiest method! I added various lines:

snes-renderer.shader=/crt/crt-easymode
fba-renderer.shader=/crt/crt-easymode
megadrive-renderer.shader=/crt/crt-easymode
etc
Thanks to all!
