Abdessamad Derraz 9646a9f429 feat: offer the other card in offline launchers
Without a network, muOS and ArkOS launchers ask to copy the BIOS files from the card the system does not read (muOS bind.sh, dArkOS roms2), then install with --from and the pack. CI checks that shellcheck is present, and the test fails under CI without it.

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, Start + Select to quit.

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.
