First of all, thank you for your answer. Off course I’ve read the wiki, and focus on the “Example Per System Control Override retroarch.cfg” part. However, i’m doing something wrong I guess…

Ok, I will try the core input option instead of the retroarch.cfg modification.

[mydriaze]

Excellent. I own one too and saw your post on Reddit. Good job!

[mydriaze]

ok, go to your config folder and open retroarch.cfg:

Look for this and modify false/true:

# video_shader_enable = true

# Smoothens picture with bilinear filtering. Should be disabled if using pixel shaders.
video_smooth = false

and:

If you know exactly the shader you want to use for all your system, simply enter the right path :

# Path to shader. Shader can be either Cg, CGP (Cg preset) or GLSL, GLSLP (GLSL preset)
# video_shader = “/path/to/shader.{cg,cgp,glsl,glslp}”

So, it will become:

# Path to shader. Shader can be either Cg, CGP (Cg preset) or GLSL, GLSLP (GLSL preset)
# video_shader = “/opt/retropie/emulators/retroarch/shader/crt-pi.glslp”

If you want a specific shader for an emulator: first open the retroarch.cfg file in the system you want to launch:

Example, for nes: \\RETROPIE\configs\nes\retroarch.cfg
add simply this line:

# Path to shader. Shader can be either Cg, CGP (Cg preset) or GLSL, GLSLP (GLSL preset)
# video_shader = “/opt/retropie/emulators/retroarch/shader/crt-pi.glslp”

Hello,

First, you have to put this file in the shader directory. You can upload it using FTP as described here: https://github.com/retropie/retropie-setup/wiki/Transferring-Roms

Then, you simply have to edit the retroarch.cfg file in the \\RETROPIE\configs\all folder by modifying 2 lines. first, tell me if you succeed transferring your roms, then we will do the 2nd part. :)

For sure i’m the dumbest guy on earth. I didn’t thought for one second that I have to push my hotkey + M or N button. Will give a try tonight.

Thanks for your help.

[mydriaze]

Ok, it’s not working properly. 15 days i’m on this issue soon, with no luck.
To edit my files, i’m simply open it in notepad+ through my local network in windows. no Putty, no FTP, pure Windows folder.

I have a keyboard, not set up. I just use it to edit metadata. I didn’t configure anything, but it works with the scraper. Pushing M or N doesn’t work at all.

Here my settings:

\\RETROPIE\configs\all\retroarch.cfg:

# Applies next and previous shader in directory.
input_shader_next = m
input_shader_prev = n

# Smoothens picture with bilinear filtering. Should be disabled if using pixel shaders.
video_smooth = false

# Defines a directory where shaders (Cg, CGP, GLSL) are kept for easy access.
video_shader_dir = /opt/retropie/emulators/retroarch/shader/

# Path to shader. Shader can be either Cg, CGP (Cg preset) or GLSL, GLSLP (GLSL preset)
# video_shader = “/path/to/shader.{cg,cgp,glsl,glslp}”

What I’m doing wrong? Thanks for your help guys. Im struggling…

[mydriaze]

oh, I haven’t seen that. I will check tonight. I will reply here if i’m getting in trouble with the set up.

Anyway, I would like to thank you for your help. I really appreciate. :)

[mydriaze]

Thanks for your reply. I’m on Retropie 3.6 at the moment.

Edit: Ok, I understand my mistake. I was speaking about ” cycling” through the shader using M and N key, not the difference between the shader “lines” in the config file (thanks for your previous reply for this).
I can’t find it on the forum, but i’m pretty sure there was an issue about this functuionnality previously…

I simply want to launch a game, then press M or N and cycle through the various shader and choose de right one. But at the moment, it doesn’t work for me. And of course I’ve seen Floob videos. :)

[mydriaze]

Any update on this?

[mydriaze]

Even with a fresh 3.6 install? That’s not possible, theorically.

[mydriaze]

When you speak about snaps, do you mean “videos”? I have a Emumovies account (for my Hyperspin), and it would be great if we can seee a short video for each game we have!

[mydriaze]

Have you check your HDMI cable? Pretty sure it’s not the right answer, but who knows, give it a try.

[mydriaze]

Thanks for your reply. :) Do you know why no one uploaded it in the shaders folder on Github (for the retropie github I mean)

[mydriaze]

Hello Davej,

On the RetroPie/common-shaders repo, the file was added on the 13/01. Is this the last version or the one you gave in this thread is the latest one?

[mydriaze]

Any update on this? I can’t cycle through the shader neither. Xboxcontroller config file seems ok, but nothing is working.

By the way, I just plugged in keyboard, but the “m” and “n” key are not working. Can someone confirm if it’s working or not at the moment with the last build?

[mydriaze]

I will give a try, thanks for the hint. ;)

[mydriaze]

Thanks for your reply. I’m not saying i don’t know how to use/scrap metadata, i’m saying that the F-zero spelling did not work properly with the scraper: FZERO, F ZERO, F-ZERO spelling didn’t match anything.

[mydriaze]

i think: video_shader is the single shader you actually want applied (assuming you have video_shader_enable set)i think: video_shader is the single shader you actually want applied (assuming you have video_shader_enable set)

Not sure about this one, cause if I want to use a specific (single) shader, I simply have to edit the retroarch.cfg file in the specific emulator folder and add the proper line.

Well, I don’t know, perhaps because i’m not english, but I didn’t understand the difference.

anyway, thanks for your reply.

Edit: any other opinion here? I still don’t understand the main difference, even with Dankcushions answer… :(

[mydriaze]

# Smoothens picture with bilinear filtering. Should be disabled if using pixel shaders.
video_smooth = false
# Path to shader. Shader can be either Cg, CGP (Cg preset) or GLSL, GLSLP (GLSL preset)
video_shader = /opt/retropie/emulators/retroarch/shader/xsal/2xsal.glslp
# Load video_shader on startup.
# Other shaders can still be loaded later in runtime.
video_shader_enable = true
# Defines a directory where shaders (Cg, CGP, GLSL) are kept for easy access.
video_shader_dir = /opt/retropie/emulators/retroarch/shader/

What’s the difference between Path to shader and video_shader_dir? I don’t get it… thanks.

[mydriaze]

Update: it’s working. Previously, I didn’t understood that I need to edit my retroarch.cfg file using sudo nano command (via putty). I edit the main retroarch file like this:

…
# video_smooth = false
# video_shader_dir = /opt/retropie/emulators/RetroArch/shader
# video_shader_enable = false
# video_shader = “/path/to/shader.{cg,cgp,glsl,glslp}”
…

What the difference between video_shader path and directory? I would like to use the hotkeys to change the shaders ingame…

…and, for example, the SNES retroarch.cfg file (i’m doing exactly the same with others emulators):

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

video_shader = “/opt/retropie/emulators/retroarch/shader/crt/crt-hyllian.glslp”
video_shader_enable = true
video_smooth = false

input_remapping_directory = /opt/retropie/configs/snes/

#include “/opt/retropie/configs/all/retroarch.cfg”

My main issue now is about crt-royale.glslp: it simply do not work at all. Any idea why guys?

[mydriaze]

Thanks for your reply. I’m trying this evening!

[mydriaze]

I’m sorry to bother you again, but I can’t find the retroarch folder as we can see here in your videos: https://youtu.be/owsdsyIDU6A?t=4m11s (neither the shader folder)

Perhaps because i’m trying to access it through Windows? Check by yourself:

That’s why I’m lost. Thanks a lot for your help.

[mydriaze]

ok, I will give a try tomorrow. Just to be sure:

1.I create a Shaders folder in Retroarch… (but I haven’t any Retroarch folder). So, I create a new one under \\RETROPIE\configs? Am I right? (I’m on Windows and i’m editing files using Windows, not directly from Retropie)

2./opt/retropie/configs/{systemname}/retroarch.cfg: I haven’t any specific line about shader in the cfg file. For example, in my NES/retroarch.cfg file, the only thing I have is:

# Settings made here will only override settings in the global retroarch.cfg if placed above the #include line

input_remapping_directory = /opt/retropie/configs/nes/

#include “/opt/retropie/configs/all/retroarch.cfg”

Do I need to add this: # video_shader = “/path/to/shader.{cg,cgp,glsl,glslp}” ?

3.Do I need to edit retroarch.cfg in my “all” folder or not?

I’m sorry if my question looks dumb, i’m realy a newbie regarding Retropie. But please let me tell you I greatly appreciate your help. :) BTW, it’s always hard for people who doesn’t speak fluently english!

[mydriaze]

Thanks for your answer. In fact, i’m lost a 3:16 min, when I see the command line “pi@raspberry -$” . I don’t even know how to get it!

I can access through my local network to \\RETROPIE\configs\all\retroarch.cfg, is it ok? Or do I need to only do this through the terminal, in command line?

Sorry again, i’m a bit lost.

[mydriaze]

Tricky one: I’m playing F-Zero on SNES. How to edit metadata? F-zero spelling find nothing. Neither F Zero, neither FZEro. I’m lost, I don’t know how to match this game with the database!
