muxterm was allowed vendor and product 0001:0001, the id gpio-keys gives the H700 pad on muOS before 2026-08-28: muxterm and gptokeyb2 both read it and every button acted twice. The allow-list is now 0000:0001, which SDL never reads back for a device (a vendor of 0 makes a name GUID, read back as 0:0), so a pad plugged in later stays hidden. - muxterm keeps PgUp and PgDn for its scrollback: in muxterm L1 and R1 send nothing, and the README and wiki stop promising paging there. - The offline detection runs with RETROBIOS_INSTALL_OFFLINE=1 instead of a closed loopback URL. - Every launcher sets RETROBIOS_IDLE_EXIT=300 for the interface. - ROCKNIX: control.ini's -sudokill goes through a sudo stub that runs nothing, so the mapper starts with -1. - The sentinel ends with its launcher, a closed terminal app writes its status, a mapper lost mid-run is said and named (gptokeyb2 included), and the unwritable-card message stays in view. - Tests: an SDL GUID model, a gptokeyb2 that outlives its kill, an interface that ignores SIGTERM, a zombie, a SIGHUP to the inner run, arrow bytes at the question, ROCKNIX's sudo.
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 do nothing in muxterm, which keeps Page Up and Page Down for its own scrollback. Hold Select, then press Start to quit. Without PortMaster, muxterm reads the pad itself (Y then ticks a system) and Menu closes it.
With no button pressed on its first screen for 5 minutes, it closes by itself: a pad the system cannot read then never leaves it stuck.
Not tried on a device yet: the icon, and whether muxterm honours SDL's controller allow-list as SDL 2.30 does.
