I’m going crazy trying to figure this out and I know it’s probably a quick fix, so please help if anyone can…I use retropie image 1.9.1, which has worked flawlessly for me since 2013…I also have an rpi2. I believe something changed when I did an rpi-update, but I can’t figure it out. I’ve messed around with all sorts of hdmi settings in boot/config.txt, but no joy. Any ideas?
