Abdessamad Derraz 5db889f538 fix: end handheld runs that lose their input
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 in the Tools menu

Copy RetroBIOS.sh and the retrobios folder next to the other tools:

System Folder Menu
ArkOS, dArkOS tools on the EASYROMS partition (/roms/tools) Options, Tools
ROCKNIX, JELOS /storage/.config/modules Tools
AmberELEC /storage/.config/distribution/modules Tools

It checks the BIOS folder against the files its emulators read and installs the missing ones: downloaded with a network connection, or from a pack copied into the retrobios folder without one.

Controls: 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. To quit, hold Select, then press Start: Start pressed first would also choose the line in focus.

ArkOS has Python 3.7, older than the installer needs: RetroBIOS uses the Python runtime the RetroBIOS PortMaster port downloads, so start that port once first.
