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.

Libretro core by beudbeud built on the Saturn/ST-V module of Mednafen
|
|
1.32.1, with an Asia ST-V BIOS setting and a stvbios.zip fallback added
|
|
to ss.cpp. Recalbox runs it for ST-V, and the loader also accepts Saturn
|
|
disc images (cue, toc, ccd, chd, m3u).
|
|
|
|
retro_init() points filesys.path_firmware at the frontend system
|
|
directory and names the BIOS of every region
|
|
(ref: libretro/libretro.cpp:608-634). The ST-V BIOS is picked by SMPC
|
|
area: Japan, Asia NTSC, Europe PAL, and North America for every other
|
|
area (ref: mednafen/ss/ss.cpp:1521-1531, mednafen/ss/smpc.h:32-40).
|
|
A Saturn disc takes sega_101.bin for Japan and Asia NTSC and
|
|
mpr-17933.bin otherwise (ref: mednafen/ss/ss.cpp:1532-1538).
|
|
|
|
The BIOS is searched in the system directory, then in the directory of
|
|
the loaded game. In each, the loose file is tried first and must be
|
|
exactly 524288 bytes. When it is missing or the wrong size, the same
|
|
name is looked up at the root of stvbios.zip in that directory, then
|
|
without the leading slash (ref: mednafen/ss/ss.cpp:1540-1582). With
|
|
ss.bios_sanity on, the default, a file named like one of the five
|
|
Saturn BIOS images must match its SHA-256. The ST-V images are not in
|
|
that table and only the size check applies
|
|
(ref: mednafen/ss/ss.cpp:1586-1633, 2647).
|
|
|
|
Saturn games that need the KoF 95 or Ultraman ROM cartridge, and the
|
|
Action Replay 4M Plus cart type, open their ROM from the firmware
|
|
directory under the default names below
|
|
(ref: mednafen/ss/ss.cpp:1421-1423, 1477-1485, 2640-2642).
