RetroBat installs its stable archives, so each config_reads entry is read at the build the binary names: Hatari 2.4.1, hatariB 0.3, Hatari2014 at ab55c3e from the buildbot, Kronos 2.7.0 and Ymir 0.3.3. SSF ships PreviewVer R28 and YabaSanshiro 1.20.32 has no public source: binary_sha256 names the file their address refs are read in. The seven RetroBat records citing an option list now hold.

notes: |
|
|
YabaSanshiro is a Sega Saturn emulator by devmiyax, forked from Yabause.
|
|
Requires OpenGL 3.3 or OpenGL ES 3.0.
|
|
|
|
Saturn BIOS search order:
|
|
1. {system}/saturn_bios.bin
|
|
2. {system}/sega_101.bin
|
|
3. {system}/mpr-17933.bin
|
|
First file found wins. Without any of the three the core refuses the
|
|
game, even with the yabasanshiro_force_hle_bios core option set
|
|
(yabause/src/libretro/libretro.c:1064-1071).
|
|
|
|
Addon cartridges: 1M/4M RAM expansion via core option (no files needed).
|
|
ROM cartridge and MPEG card ROM loading disabled in libretro port
|
|
(cartpath = empty, mpegpath = NULL).
|
|
|
|
BIOS loading: retro_load_game() at yabause/src/libretro/libretro.c:1048-1071.
|
|
Core load: LoadBios() at yabause/src/memory.c:1353-1356, T123Load() at yabause/src/memory.h:219-289.
|
|
|
|
Standalone: the retro_arena SDL2 front end of the sydarn/yabause
|
|
pi4-update branch, built with -DYAB_PORTS=retro_arena. It prints version
|
|
1.11.beta3 (yabause/CMakeLists.txt:15-18, yabause/src/config.h.in:5). It
|
|
opens a BIOS only at the path given with -b or --bios, under any name.
|
|
Without it biospath stays NULL and the core runs its HLE BIOS
|
|
(yabause/src/retro_arena/main.cpp:161, yabause/src/retro_arena/main.cpp:230-234,
|
|
yabause/src/retro_arena/main.cpp:325-328, yabause/src/yabause.c:373-388).
|
|
The image is read through T123Load, which truncates a file above 512 KiB
|
|
and checks nothing else (yabause/src/memory.c:1400-1403,
|
|
yabause/src/memory.h:219-242). A -b path that cannot be read stops
|
|
YabauseInit. The MPEG card and ROM cartridge paths stay empty, so no
|
|
other firmware is read.
|
|
|
|
ROCKNIX passes -b with the first of saturn_bios.bin, sega_101.bin,
|
|
mpr-17933.bin, mpr-18811-mx.ic1, mpr-19367-mx.ic1 and stvbios.zip found
|
|
under its BIOS folder when its use_hlebios setting is 1
|
|
(ROCKNIX projects/ROCKNIX/packages/emulators/standalone/yabasanshiro-sa/scripts/start_yabasanshiro.sh:80-91).
|
|
AmberELEC passes saturn_bios.bin from its BIOS folder unless HLE is
|
|
selected (AmberELEC packages/games/emulators/yabasanshiroSA/yabasanshiro.sh:63-70).
|
|
Both build the pi4-update tip and patch the home directory to
|
|
/storage/.config/yabasanshiro.
