Technical notes

System ROMs embedded in binary: C64 BASIC (901226-01), chargen (901225-01), chargen Japanese (906143-02), kernal Rev 3 (901227-03), kernal GS (390852-01), kernal SX-64 (251104-04), kernal 4064 (901246-01), kernal Japanese (906145-02), plus all drive ROMs (1540, 1541, 1541-II, 1551, 1570, 1571, 1571CR, 1581, 1001, 2031, 2040, 3040, 4040, 9000) and VIC-II palettes. Embedded ROM check in sysfile_load takes priority over filesystem. Kernal Rev 1 (901227-01) and Rev 2 (901227-02) are NOT embedded; selecting C64 OLD NTSC or C64 OLD PAL model requires them on the filesystem in system/vice/C64/. JiffyDOS requires True Drive Emulation enabled and a 1541/1571/1581 drive type. SX-64 models use a separate JiffyDOS kernal (JiffyDOS_SX-64.bin) not declared in the .info.
