@Crispy Success. If anything fails then reflash RetroPie and update. It usually works every time. Your welcome. :-)

@JKimRX
Is it a keyboard with a Fn key? Make sure capslock and numlock are off, some of them have a Fn lock ya know. Also retropie uses UK default so it is a good idea to change now to US using raspi-config if you use that layout.

@hostolis
Yes, vnc works, I just tried.

@de_jean125 Something like that, yes. :)

My first guess was that it was for your kid(s), by the way.

You could even let it get nastier … "Stop or I'll hack into your bank account and send all of your money to homes for retired game programmers!"

@meleu @cyperghost The export did the trick. It works now and doesn't break the other menu controls. 😄 Thank you for all the effort and explanations. I learned a lot today, as may others who stumble upon this thread, too.

I edited my opening post to a mere reference to @meleu's solution. 😌

Edit: I had something here about killing Joy2key, but after reading your post more carefully, it wouldn't apply. I'm not sure keyboard input can be ignored here. I assume you know that the Runcommand menu can be deactivated altogether.

@chuck_b Yes, whenever you update all installed packages or just ES from the setup script.

I would keep a copy of the new ES binary with the remapped quit key and then, after updating, you can overwrite the ES binary with your modded version, unless, of course, there is a new feature in ES that you desire, in which case, you would need to recompile.

@quicksilver I already knew that, but thanks anyway, I am starting to use that until I get a new keyboard.

How did you do the update ? Have you updated all packages or picked some of them and updated ? As @TheDataCereal said, ES seems so be missing so you should re-install it from the setup script.

@mitu I did add the line myself, I just mean is there a way to get the file through WinSCP so I can post it on here? I tried looking through my computer connected to it on that but I couldn't find it. I couldn't find the folder it was in.

@mitu , thank you for your reply.
There is no specific problem, just trying to increase my knowledge about how does the retropie_setup script works.
=)

@BuZz , thank you. I'll try it! I believe this should also work for the other piece of codes. ;)

@Trailjacker , I'm happy my question was useful in you scenario.

Thank you guys!

Plug in a keyboard and press f4

Problem solved, I did
sudo nano /home/pi/.emulationstation/es_systems.cfg to get to the file you write the system code and I just deleted what I wrote concerning Kodi as a standalone system. Then I saved it and opened Emulation Station and it was fine. I think what happened is since I couldn't do ~/RetroPie/roms/kodi I just copied what the other ones had there instead.

Thanks, I'm trying out the fonts.

By the way, for anyone missing the cursor in MC: in my case, exiting EmuStation and running "mc" from the terminal makes the cursor visible. Perhaps it's ES that hides it.

What are you using to SSH in the Pi? You should be using Terminal, comes pre-installed on all macs. Open terminal and type: ssh pi@192.168.5.25 (but use whatever your Pi's IP address is) password is: raspberry

@shareef Thanks for sharing your solution.
