Stella 2023¶
Technical notes
Frozen snapshot of Stella development branch (7.0_pre, copyright 2024). The .info reports display_version 6.6 which does not match the source (src/common/Version.hxx defines STELLA_VERSION as "7.0_pre").
The Atari 2600 has no BIOS ROM: TIA, RIOT, and 6507 CPU are fully emulated in software. The SuperCharger (Starpath) BIOS is emulated via a built-in dummy ROM (ourDummyROMCode in src/emucore/CartAR.cxx:279). The game properties database is compiled into DefProps.hxx, and external loading is disabled in the libretro port (OSystemLIBRETRO returns CompositeKeyValueRepositoryNoop for the property repository).
The libretro interface does not call RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY and declares no firmware requirements (firmware_count=0 in .info).
KidVid Voice Module audio tapes (7 WAV files) are checked via FSNode::exists() in baseDir (resolves to content directory in the libretro port). SoundLIBRETRO does not override playWav()/wavSize() from the base Sound class, so WAV playback is non-functional. Games work without WAV files using a timing-based fallback in KidVid::setNextSong().
EEPROM save data for AtariVox and SaveKey peripherals is managed as NVRAM, not user-supplied.
