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.
Notes
RetroBIOS runs the RetroBIOS installer (install.py, from
github.com/Abdess/retrobios) on the
device, in its full-screen interface. The installer finds the BIOS folder of
the system, checks every file its emulators read against its hash, and
installs the missing ones.
With a network connection the files are downloaded. Without one, copy the
BIOS pack of your system (a _BIOS_Pack.zip file from the releases page)
into ports/retrobios on the card, and RetroBIOS installs from it.
Python 3.8 or newer: the system's, or PortMaster's python_3.11 runtime on
aarch64, downloaded on first use.
Under a desktop session with neither foot nor xterm, RetroBIOS opens PortMaster's own screens instead of the full-screen interface.
