How to run a command line from USB

DarkWolf

@stevefo So what is the problem now? Accessing/editing the files?
If so, you can edit those using nano:

sudo nano <file path>

And save with

ctrl + x, enger
y, enter

@stevefo said in How to run a command line from USB:

@DarkWolf Here is what I tried to do. Once I'm in command prompt on pi, I typed in each command line and neither would work.

Curvature on the shader
Remember, you can disable the curvature on the shader by editing
/opt/retropie/emulators/retroarch/shader/arcade-bezel-shader/shaders/crt-pi.glsl
/opt/retropie/emulators/retroarch/shader/arcade-bezel-shader/shaders/crt-pi-vertical.glsl

#define CURVATURE = Curvature ON
//#define CURVATURE = Curvature OFF

you don't need to do any of that. just instead of using the crt-pi shader, use the crt-pi-curvature shader. we package both.

@dankcushions @ darkwolf,

Could you type the command so I can copy and paste?

stevefo

@dankcushions

Is that in the settings of video manager? I don't see that option. It's the latest version 1.2

DarkWolf

@stevefo

sudo nano /opt/retropie/emulators/retroarch/shader/arcade-bezel-shader/shaders/crt-pi.glsl

sudo nano /opt/retropie/emulators/retroarch/shader/arcade-bezel-shader/shaders/crt-pi-vertical.glsl

But you should check what @dankcushions wrote

@DarkWolf It looks like I may be able to change these settings in retroarch.

https://github.com/RetroPie/RetroPie-Setup/wiki/Shaders-and-Smoothing#installation

I'll try it later when I get home from work.
I'll keep you posted.

I really appreciate your help.

DarkWolf

@stevefo That looks like what you searched for:
Would especially recommend this wiki page:
https://github.com/RetroPie/RetroPie-Setup/wiki/Configuration-Editor

stevefo

@DarkWolf well, I messed something up in the settings and lost overlay borders and still could not get rid of screen curvature.

All I really want are Arcade bezel overlays. It shows here how to manually install just those but I don't understand it.

@stevefo
I have like 0 time this morning... so I will try to write something on the go later!
But you will need a usb drive and ssh OR a program like winSCP

DarkWolf

@stevefo Ok, so assuming you removed the video manager (e.g. by reinstalling retropie)

And to clear some things up here:
The video manager is just a tool that downloads the shaders and overlays for you and is applying it to the corresponding config files. It is not needed for using shaders or overlays! This function is already implemented into retropie.

Ok, let's start:

Download the overlay zip and unzip it
Taken of the installation page:

Arcade Bezel overlays (John.Merrit)
https://mega.nz/#!eNIGyIrB!sgJf4lDXI-YOtVd-u49QmX1qL7ECRMjB95nNf8Meqow
/opt/retropie/emulators/retroarch/overlays/ (put folder in zip file above in here)

Hardest part: Copying the files to your pi:

If you have a programm like winSCP:

Connect to your pie

Navigate to `/opt/retropie/emulators/retroarch/overlays/

Copy the folder with the overlays into there

If you have a usb drive and a ssh connection:

Copy the folder with the overlays onto the root of your usb drive (rename the folder to bezels_overlays)

Plug the usb drive into your pi

Connect via ssh

Type this (one command)
cp -rv /media/usb0/bezels_overlays /opt/retropie/emulators/retroarch/overlays

On Emulationstation:
Open this page and navigate to the menu shown in the Basic Configuration
Look at the last/third screenshot:
Set Overlay Enabled to true
and Overlay File to wich image you want as overlay
That's it

@DarkWolf it messed up the format of my reply but I guess it's readable

stevefo

@DarkWolf Ok, just did a fresh install of retropie. I'm running late too. I'll try this method later this evening.

I'll check back to see if you have changed anything before I try it. I'll be using the SSH route.

Thanks for your continued help.

DarkWolf

@stevefo Updated it a bit, hope that helps :)

stevefo

@DarkWolf If it's not one thing it's another. I only use a MacBook. Anything I download from Mega gets messed up on here. I can never get mega to work on a mac.

stevefo

@stevefo The arcade bezel overlays are from through Mega downloader.

stevefo

@stevefo I got the file. It let me download form browser.

stevefo

@stevefo ok, got it to work. The Arcade overlays are so good that they work better with screen curvature. I get overlap when it's flat. Damn!

Thank You for your help, I really appreciate it. I have another question that should be easy to answer but not sure it's allowed. Can I message you? If so, how?

I have another question that should be easy to answer but not sure it's allowed.

As long as it doesn't break any of these rules, you'll be fine.

DarkWolf

@stevefo Haha, we needed some time here, but now it's working, great!

Regarding your question: Sure, but like @mediamogul said:

As long as it doesn't break any of these rules, you'll be fine.

Check this first ;-)

@DarkWolf I have some MAME games that don't work. I've tried Mame 4 all, mame lb, and mame 2003. Any suggestions?
