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.

Using it with an emulator usually bypasses the loading process, injecting the file directly into the memory, and then automatically runs it (so there is no tape, disc or cartridge inserted).
