Start + Select now kills a sentinel the launcher owns, and the launcher asks the interface to stop, so a running install still writes its result. A mapper that dies, a chvt the compositor refuses, a terminal app that cannot open and a read-only card each end the run or hand over to the next route instead of a console waiting for a button. muOS starts gptokeyb2 with -X and keeps muxterm off the pad so Y opens the options.

RetroBIOS for muOS
Copy RetroBIOS.muxapp to the card, open it from muOS's archive manager to
install it, then start RetroBIOS from Applications.
It checks the BIOS folder (/run/muos/storage/bios) against the files its
emulators read and installs the missing ones: downloaded with a network
connection, or from a pack copied to the root of the card without one.
It runs in muxterm, muOS's terminal. With PortMaster installed, gptokeyb2 turns every button into a key and muxterm is told to leave the pad alone, so each button is sent once: D-pad to move, A or Start to choose, B or Select to go back, X to tick a system, Y for the options, L1 and R1 to page. Hold Select, then press Start to quit. Without PortMaster, muxterm reads the pad itself (Y then ticks a system) and Menu closes it.
Not tried on a device yet: the icon, and whether muxterm honours SDL's controller allow-list as SDL 2.30 does.
