  System ROMs embedded in binary: C64 BASIC (901226-01), kernal Rev 3
  (901227-03), chargen (901225-01), plus all drive ROMs (1540, 1541, 1541-II,
  1551, 1570, 1571, 1571CR, 1581, 1001, 2031, 2040, 3040, 4040, 9000).
  Embedded ROM check in sysfile_load takes priority over filesystem.
  DTV has its own color system (viciidtv-color.c); external palette loading
  is disabled. JiffyDOS is not supported (excluded from build conditionals).
  The .info declares 4 JiffyDOS firmware (firmware_count=4) but the code
  never loads them for this core. The .info also omits dtvrom.bin.

      Loaded via sysfile_load from system/vice/C64DTV/. All model variants
      (V2 PAL/NTSC, V3 PAL/NTSC, Hummer) default to this filename. If not
      found, the core copies embedded BASIC, kernal and chargen ROMs into
      flash memory. Without it, the DTV operates as a basic C64 without the
      built-in DTV games and firmware. The original DTV ROM has distorted
      colors; a patched ROM is recommended.
