Edit: It works, many thanks.

@aimbit said in Flashing (outdated?) image to a new Pi 4 - Error Message on boot (Req. new software):

Is this something I can update on there, make a new backup image, and flash to my newer pi?

Update your system from the RetroPie-Setup on the old system - say yes when asked to update the included kernel and OS packages - then transfer again a backup to the new system.
