notes: |
|
|
The libretro core is built from stella-emu/stella, the tree of the
|
|
standalone emulator, with its wrapper in src/os/libretro. The binary
|
|
reports library_name "Stella" (src/os/libretro/StellaLIBRETRO.hxx:59)
|
|
and the version of src/common/Version.hxx:35. The stella_libretro.info
|
|
lists display_version "6.6".
|
|
|
|
The Atari 2600 has no BIOS ROM: TIA, RIOT and 6507 CPU are emulated in
|
|
software. The SuperCharger (Starpath) BIOS is replaced by built-in code
|
|
(ourDummyROMCode in src/emucore/CartAR.cxx:635).
|
|
|
|
The libretro core reads the system directory (src/os/libretro/libretro.cxx:1716-1724)
|
|
but nothing reads the path it stores. Its base directory is a stella
|
|
folder under the save directory, or ./ without one
|
|
(src/os/libretro/OSystemLIBRETRO.hxx:71-79). The standalone base
|
|
directory is the configuration directory, $XDG_CONFIG_HOME/stella on
|
|
Linux and the application data folder on Windows
|
|
(src/os/unix/OSystemUNIX.cxx:79, src/os/windows/OSystemWINDOWS.cxx:32).
|
|
|
|
KidVid Voice Module tapes: the tape the game selects and KVSHARED.WAV are
|
|
looked up in KidVidAudio.zip in the base directory, then loose in the
|
|
base directory, and both must be present (src/emucore/KidVid.cxx:255-268).
|
|
The archive holds the same seven files listed below.
|
|
The libretro build compiles with SOUND_SUPPORT and ZIP_SUPPORT
|
|
(src/os/libretro/Makefile:599) and plays them (src/os/libretro/SoundLIBRETRO.hxx:127-133).
|
|
Without them the game runs on a timing-based fallback with a beep
|
|
(src/emucore/KidVid.cxx:343-348).
|
|
|
|
EEPROM save data for AtariVox and SaveKey peripherals is managed as
|
|
NVRAM, not user-supplied.
