Technical notes

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.
