Abdessamad Derraz 801a0150e6 feat: run the handheld launchers in the tui
The PortMaster port now starts install.py --tui on the console (or in
foot or xterm under a compositor), with gptokeyb in kill mode on the
installer's path, retrobios.gptk, TERM=linux and a Terminus font, and
puts the console, font and mapper back on exit. pugwash screens stay as
the fallback where no terminal can show, and start in no-check mode so
PortMaster's A/B fix applies. Without a network, every launcher installs
from a pack found on the card or names the pack and the folder.

Adds launchers for Batocera and Knulli (Ports, evmapy .keys), muOS
(.muxapp in muxterm with gptokeyb2) and the Tools menu of ArkOS,
dArkOS, ROCKNIX, JELOS and AmberELEC, built by build_port.py with the
pinned installer and tested on a simulated device.

RetroBIOS for Batocera and Knulli

Copy RetroBIOS.sh, RetroBIOS.sh.keys and the retrobios folder into roms/ports on the SHARE partition (/userdata/roms/ports), update the game list, then start RetroBIOS from Ports.

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

The controller drives it through RetroBIOS.sh.keys: 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. B on the first screen closes it.

Not tried on a device yet

EmulationStation covers the text console on Batocera and Knulli, and no terminal for a script is documented there. RetroBIOS opens xterm (the X11 builds) or foot when either is installed, else switches to console 4, runs there, and switches back. Which of the two shows up on a given build is not verified. If the screen stays black, retrobios/log.txt says which route was taken, and the computer route always works: with the card mounted, run the one-line command from abdess.github.io/retrobios/wiki/installer.
