notes: |
  Frozen snapshot of Stella 3.9.3. The Atari 2600 has no BIOS ROM; the TIA,
  RIOT, and 6507 CPU are fully emulated in software. The SuperCharger (Starpath)
  BIOS is emulated via a built-in dummy ROM (ourDummyROMCode in CartAR.cxx:518).
  Game properties database (stella.pro) is compiled into DefProps.hxx; external
  loading is disabled in the libretro port (PropsSet.cxx:35). The core does not
  call GET_SYSTEM_DIRECTORY. KidVid Voice Module audio tapes (7 WAV files) are
  loaded via rfopen with relative filenames from the content directory
  (KidVid.cxx:166-185); absence is handled gracefully. EEPROM save data for
  AtariVox and SaveKey peripherals is managed as NVRAM, not user-supplied.
