Technical notes

VICE is a multi-machine Commodore emulator covering C64, C128, VIC-20, Plus/4, PET, CBM-II, C64 DTV, and SuperCPU64. Each machine is built as a separate libretro core.

All standard ROMs (kernal, basic, chargen, drive DOS, editor) are embedded in the core binary via USE_EMBEDDED. External ROM files are NOT required for normal operation. The embedded ROMs are compiled from vice/data/<machine>/ and ship with every build.

The core looks for optional external data in system/vice/<machine>/ (e.g. system/vice/C64/, system/vice/C128/). This is used for: - JiffyDOS replacement kernals (proprietary, not included) - SuperCPU external kernals (scpu-dos-1.4.bin, scpu-dos-2.04.bin) - Cartridge images placed in system/vice/<machine>/ - Custom keymaps (.vkm files) - Custom vicerc configuration

JiffyDOS support (C64/C64SC/C128/SCPU64 only): Requires True Drive Emulation enabled and 1541/1571/1581 drive type. ROMs are loaded from system/vice/: - JiffyDOS_C64.bin (C64 kernal replacement) - JiffyDOS_SX-64.bin (SX-64 model kernal replacement) - JiffyDOS_C128.bin (C128 kernal replacement, C128 core only) - JiffyDOS_1541-II.bin (1541-II drive DOS replacement) - JiffyDOS_1571_repl310654.bin (1571 drive DOS replacement) - JiffyDOS_1581.bin (1581 drive DOS replacement)

SuperCPU kernal (SCPU64 core only): Option "SuperCPU Kernal" selects between Internal (embedded), 1.40, or 2.04. External kernals loaded from system/vice/SCPU64/: - scpu-dos-1.4.bin - scpu-dos-2.04.bin These files are blacklisted from the cartridge scanner to prevent accidental loading as cartridges.

C128 libretro specifics: the C128 core reuses C64 ROM filenames for C64 mode (basic-901226-01.bin, kernal-901227-03.bin) instead of the standalone VICE names (basic64-901226-01.bin, kernal64-901227-03.bin). This is controlled by #ifdef LIBRETRO in c128rom.h.

Drive ROM notes: dos2000, dos4000, and CMDHD boot ROM are defined in driverom.h but not shipped in vice/data/DRIVES/. These are for CMD hardware (FD-2000, FD-4000, CMD HD) which are rare peripherals.
