# RetroBIOS for Batocera and Knulli, started from Ports: checks the BIOS
# folder and downloads the files it lacks, in the installer's full-screen
# interface. Batocera gives the controller the keys of RetroBIOS.sh.keys
# (evmapy) while this runs.
#
# The interface needs a terminal the player can see, and EmulationStation
# covers the console. In order: xterm or foot in the graphical session, else
# console 4 switched to and back from. Console 4 because Batocera's exit
# hotkey sends Alt+F4 (batocera_launch emulators/sh.py), which on a console
# switches to console 4: there it leaves the interface where it is.
