hdmi_group=1

Tried saving the file with the new settings, but it says the file is locked and won't let me save

@lektroid How are you editing the file ? If you're using an editor from the PI, make sure you're using sudo when you start the editor, the file is not editable by the pi user, since it's a system file.

@mitu I'm plugging the SD into the mac, then using Textedit to edit the file (It's the only way I know), not sure how to use sudo?

mitu

You don't need sudo if you're editing the file on macOS.

So, what's the best way to edit it, since MacOS won't save the file?

mitu

Just edit it from the Pi. Exit EmulationStation and then run

sudo nano /boot/config.txt

to edit the file. Reboot after saving the file, by running sudo reboot.

@dankcushions Thanks for your reply, but this is not working. I have followed the instructions to the word, inserted all the information into Cyberduck exactly, there is nowhere to add an IP address in Cyberduck, so obviously I could not enter that, and it refuses connect.

there sure is - i use it myself:

Open Connection > Server prompt.

I have this running now, thanks for the image, I was entering a server name where the IP should go.

However, I still cannot save the file, it says "Permission denied. Please contact your web hosting service provider for assistance." and refuses to overwrite.

How can I give permission to the file so it will save?

@lektroid it looks like the file is owned by root and i'm not sure how to give cyberduck sudo - i don't use it for editing files, just accessing and transferring. i would follow @mitu 's advice as to how to edit it via commandline.

LektroiD

@dankcushions I'll have a go, but I'm no commandline guru, hopefully I can work it out.

I'm just confused as to why I am unable to access the screen resolutions from the Display Options menu, is something broken?

All sorted, the emulator is working perfectly. Thanks for all your help, and thanks also for putting up with my incompetence.

A huge thanks from both my wife and myself. We are both delighted!

Hi. I'm popping in late on this one but I wanted to point something else out to you while you travel down the Retropie path. Unlike other single source software that is written by one person and constantly updated by the same... Think or Retropie as a huge umbrella that a ton of individuals came together under to get all these emulators to work with each other.

Many of the emulators have been tweaked to specifically work in the Retropie world, so it will pay you back 10 fold to start to become familiar with some Linux commands and how it works. Don't have to be an expert, but as you add emulators and what they need to work, it will help a lot.

Download Putty and if you are using a PC WinSCP. They are for getting straight in to the PIs file system and working with it. You can use a Mac, but again, it's not always the same as just using mac files. Linux requires permissions to be changed on folders, files..etc.

Also... Commodore 64... If you are using Vice, there is a great video on youtube by a guy named ETAPrime who shows you how to configure the buttons to work the emulator. There is also lr-vice you can download sperately that will pickup the standard Retroarch joystick button commands.

Either way you'll need to read and research many of the emulators as you add them. Many need special configurations to use properly. Take one at a time. I have 43 systems running on mine. Took me almost a year to get them all working correctly...or as best that I could.

Good luck, come back often to ask questions. You're only 'incompetent' because you don't have knowledge. Knowledge is all about effort. Max effort = max knowledge.
