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