Change screen ratio menu recalbox

[polandluigi]

I have my recalbox connected to a 16:9 7 inch screen via HDMI. Is there a way I can force the Menu screen to fit to a 4:3 scale on my screen? At the moment the menu is widescreen, and would prefer it to be forced into a 4:3 ratio. Is there a different config file to be edited please?

@polandluigi Check the Emulationstation menu, there are several different options, one of them is the screen ratio, there is even a "perfect pixel" option (I'm not sure of the right term in English), which forces the game to its original resolution.

@zing I don't mean games. I want to change the Recalbox aspect ratio. It is possible?

@polandluigi Yes, it is possible, you can change the videomode in the recalbox.conf file, or you can go further and change it in the recalbox-user-config.txt file (you will find several topics talking about the config.txt file, but the file recalbox-user-config.txt keeps your changes after an upgrade, config.txt does not).
