  System ROMs embedded in binary: BASIC (901486-01), chargen (901460-03),
  kernal PAL Rev 7 (901486-07), kernal NTSC Rev 6 (901486-06), plus all
  drive ROMs (1540, 1541, 1541-II, 1551, 1570, 1571, 1571CR, 1581, 1001,
  2031, 2040, 3040, 4040, 9000) and VIC palettes. Embedded ROM check in
  sysfile_load takes priority over filesystem. Japanese VIC-1001 model
  requires kernal Rev 2 (901486-02) and chargen (901460-02) on the
  filesystem in system/vice/VIC20/; this model is not exposed via core
  options (only via vicerc). No JiffyDOS support for VIC-20.
