Hi guys, I'm trying to force a 4:3 ratio on my HDMI output so that all the retro games will display at 4:3 correctly in DosBox on my 800x480 display.
In config.txt, this should be
but actually nothing I do in config.txt seems to make any difference.
There is a config.txt at the root, but I read that it should be in boot\config.txt - there wasn't one there to begin with so I copied it there with my changes, but still no effect.
I'm a bit new to Raspberry Pi - any advice?
