So, I've been "encouraged" by my friends to set up Pi 3s for them since they have no idea how to. I had been planning on just using Retropie, but when I showed it to them they panicked when they accidentally got into a config screen. So, my question is, what is the best image that makes it hard to get into the system config files so they can't screw it up, but still allows you into them if you need to? LOL.

Also, I only have 64gb cards to work with, and an internet cap (so I can't download all the images to try unfortunately). :'(
