Abdessamad Derraz b29500846b feat: read retrobat's saturn and atari builds
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: |
Kronos is a Sega Saturn and ST-V arcade emulator by FCare, forked from
Yabause. Requires OpenGL 4.3 compute shaders.
Saturn BIOS search order:
1. {system}/kronos/saturn_bios.bin
2. {system}/saturn_bios.bin
3. {system}/sega_101.bin
4. {system}/mpr-17933.bin
First file found wins. Real BIOS required (HLE deprecated, only available
via kronos_force_hle_bios core option for debugging).
ST-V BIOS: {system}/kronos/stvbios.zip or {system}/stvbios.zip
MAME-style ZIP containing region-specific EPROMs. Kronos picks the best
match by game region and kronos_stv_favorite_region core option (EU/US/JP/TW).
ROM cartridges for KOF95 and Ultraman are auto-detected via game database
(db.c) and loaded from system_dir when the corresponding game is running.
BIOS loading: retro_load_game() at yabause/src/libretro/libretro.c:1601-1727.
STV blob table: BiosList at yabause/src/ctrl/src/stv.c:112-136.
ROM cartridge DB: yabause/src/utils/src/db.c:43-45.
Standalone supports MPEG card ROM loading (Video CD card). Disabled in
libretro port (mpegpath = NULL in yabause/src/libretro/libretro.c:1578).
