Commodore VIC-20
The Commodore VIC-20 is an 8-bit home computer developed by
Commodore. It was released in 1980.
In Germany, it was known as the “VC-20” instead, due to the
rather unfortunate similarity between the pronounciation of “VIC”
with another certain German word…
The VIC-20 was succeeded by the Commodore 64 two years later.
This system scrapes metadata for the “c64” group and loads the
c20 set from the currently selected theme, if available.

This needs confirmation.
No Commodore VIC-20 emulator in Batocera needs a BIOS file to run.
ROMs
Needs polish/alternatives/automated script(?)
Place your Commodore VIC-20 ROMs in /userdata/roms/c20.
For now, ROMs must be manually specified in VICE in order to use them with its VIC-20 emulator.
