This page is about running retropie from sd card and roms from external hard drive in 2022.I used to like to run from one image. Not anymore.
Rom set should work against pi3/pi4. I want to be able to update OS easier.
I have old pie boots that have some issues. Would be better to re-flash updates to SD Card. Then play off external.This way I can be sure latest image is clean.My plus 1 build is on 4.5.2 Raspbian stretch. Now we are on Buster and I don't think it's safe to just update. OS is not meant to just update.
