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.
