Can't change shader anymore ! Help !

Nataq

Ok I have found the problem ! (EDIT: No I didn't ! read following posts pls.) Or part of it. It's the shader path :)

How I got there :

First, what I did is fix my binding for the Retroarch GUI to work in MAME.

Then I loaded up the jrpacman game and using the retroarch GUI, I have selected a shader (crt-pi-vertical) and saved the override (.cfg) from the menu. Then I went into /opt/retropie/configs/all/retroarch/config/MAME 2003/ to look inside the just created jrpacman.cfg file. Among a lot of lines I found this one :

video_shader = "~/.config/retroarch/shaders/retroarch.glslp"

The path is strange and it is not even pointing to the crt-pi-vertical shader I just tried to save. Anyway, I figured I'd try to use that path and I just replaced the "retroarch" part by "crt-pi-vertical" so the line is now :

video_shader = "~/.config/retroarch/shaders/crt-pi-vertical.glslp"

And bingo ! (EDIT: I thought it was working but its not ! Read following posts) The crt-pi-vertical shader now loads properly when I launch the game ! So in any config files I want to change the shader, I need to use that strange path. I can now fix all my games .cfg.

All is good but I still would like to know why I have to use that strange path while everyone else has just to point to "/opt/retropie/configs/all/retroarch/shaders/crt-pi-vertical.glslp" for this to work. I can see the shaders in that path !

Any ideas ???

@Nataq ~/.config/retroarch/ is a symlink to /opt/retropie/configs/all/retroarch in retropie - it's the same location - or should be unless something is broken on your set-up.

@BuZz

Ok. Make sense. Would like to know how I can fix that although I can make it work by using the alternate path.

@Nataq your main retroarch.cfg may have the wrong path in it - but it should work with the other path. Not sure why the wrong shader file was put in there though.

@BuZz

Does my main retroarch.cfg need to specify the shader path ? Right now its not. I thought it isn't necessary since the shader path is specified in all my per game retroarch.cfg.

I am wondering about those lines in the all retroarch.cfg :

Defines a directory where shaders (Cg, CGP, GLSL) are kept for easy access.

video_shader_dir =

Is that mandatory ? What kind of "easy access" does that option provide ?

I can always try to specify the path there... Can't try right now since i'm not home.

Edit: There is the "#" symbol in front of those line. Not sure how to display .cfg properly in the forum...

@Nataq Please format configs in a code block for readability - http://commonmark.org/help/ otherwise # gets interpreted as a heading.

actually, the default shader path should be ok - as it should be a symlink.

what's the output of

ls -l ~/.config/retroarch

@BuZz said in Can't change shader anymore ! Help !:

ls -l ~/.config/retroarch

Got this :

lrwxrwxrwx 1 pi pi 35 Nov 5 21:26 /home/pi/.config/retroarch -> /opt/retropie/configs/all/retroarch

@Nataq so the other path should work too - unless retroarch doesn't like symlinks for some reason.

Nataq

Yeah that's the thing. It doesn't like it hehe. Ho well, as long as I have a way to do it :) Thanks for looking !

Nataq

Turns out it still doesn't work ! :(

I thought it did since I used the alternate line AFTER I changed the shader using the Retroarch GUI. Now even if I delete the new line or change it, no change to the shader :(

Somehow, changing the shader through the Retroarch GUI does it, whatever is in the retroarch.cfg file.

Now what I'm thinking, could it be something to do with file permissions ? That shader line, does it tell the system to change another file properties and maybe it isn't able to do it because of file permission ?

I am thinking about this since I see other posts about file permission issues, requiring to do something like :

Sudo chown pi:pi /opt/retropie/configs/

Could that help ??? At work right now...
