Each libretro profile records version_basis and core_version is read there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba 0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build takes its version from git carry the nearest tag in describe form (flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders copied from .info files (Git, SVN) are replaced by the code's statement, and a code that states none is null with kind none.

exclusion_note: >
|
|
The system directory is asked for and stored (src/core.cpp:362-366), and the
|
|
helpers that would read it back sit inside comment blocks
|
|
(src/common.cpp:799-937, src/common.cpp:1095-1719): the answer is never used.

notes: |
|
|
Cassette Vision emulator written for libretro by Maxime Marconato. The
|
|
console has no system ROM: each cartridge carries the NEC uPD777 (or
|
|
uPD778) that runs it, so the cartridge dump is the whole machine.
|
|
|
|
Content is opened from its full path (need_fullpath = true,
|
|
src/core.cpp:307) with a plain fopen (src/emu.cpp:138,
|
|
src/fileio.cpp:84-93). The file must be exactly 4064 bytes, the 2032
|
|
valid program addresses as 16-bit words (src/emu.h:16, src/emu.h:223,
|
|
src/emu.cpp:143-153). Any other size zeroes program memory and leaves
|
|
the cartridge not inserted. Each word is read as a big-endian 12-bit
|
|
instruction (src/emu.cpp:159-164). The commented MD5 check at
|
|
src/emu.cpp:313-320 is not compiled.
|
|
|
|
The uPD778 character generator (128 patterns of 7 lines) is a static
|
|
table compiled into the core, pattern_778c at src/emu.cpp:168-307, and
|
|
is never read from disk.
|
|
|
|
RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY and GET_SAVE_DIRECTORY are
|
|
queried at init and stored (src/core.cpp:362-366, src/core.cpp:377-381,
|
|
src/common.cpp:1054-1094). Nothing reads them back: the path helpers
|
|
inherited from the Common Source Code Project (get_application_path,
|
|
create_local_path, the ini reader and writer) sit inside comment blocks
|
|
(src/common.cpp:799-937, src/common.cpp:1095-1719). Core options are
|
|
not registered, f_retro_load_settings and f_retro_save_settings are
|
|
empty (src/core.cpp:2562-2895, src/core.cpp:2900-3099). No save RAM
|
|
(src/core.cpp:3437-3450) and no save states (src/core.cpp:3374-3390).
|
|
|
|
The .info declares firmware_count = 0 and matches the code.
