Hello,

You have to use 'sudo' before nano or vi commande.
example : sudo vi /boot/config.txt

If you want use filezilla or WinSCP to modify config.txt file, you must be connected as root.

If you're editing the file from the Raspbian desktop, Leafpad (or similar) will only open with standard permissions if you use the menu or desktop icon.

You can launch a text editor with super-user permissions from the command line:

sudo leafpad

optionally you can directly open the config.txt file in the editor with superuser rights with:

sudo leafpad /boot/config.txt

I'd always advise making a backup of config files before altering anything:

sudo cp /boot/config.txt /boot/config.txt.bak

press F4
or 'shutdown emulationstation' in the shutdown options.
