Recalbox builds seven board images with different emulators. The new target scraper reads each board's defconfig against the package every system.ini core names. The names that reached no profile are mapped to the projects Recalbox builds or profiled from their source, and the mupen64plus video plugins are set aside.

|
|
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; 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:615-641). 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:1436-1446, 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:1447-1453).
|
|
|
|
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 the system directory, then without the leading slash
|
|
(ref: mednafen/ss/ss.cpp:1455-1491). 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:1493-1540, 2549).
|
|
|
|
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:1348-1350, 1404-1412, 2542-2544).
