+notes: |
+  Kronos is a Sega Saturn and ST-V arcade emulator forked from Yabause.
+  The libretro repo at libretro/yabause ships the older "Yabause" core
+  (yabause_libretro) which handles Saturn only and has no STV support.
+
+  Saturn BIOS search order (Kronos):
+    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 is deprecated and causes
+  issues. Multi-disc (m3u) also forces real BIOS.
+
+  Saturn BIOS search order (YabaSanshiro / Yabause):
+    1. {system}/saturn_bios.bin
+    2. {system}/sega_101.bin
+    3. {system}/mpr-17933.bin
+  Falls back to HLE if none found, but HLE is not recommended.
+
+  ST-V BIOS (Kronos only):
+    {system}/kronos/stvbios.zip or {system}/stvbios.zip
+  The ZIP is a MAME-style romset containing region-specific EPROMs.
+  Kronos picks the first matching BIOS by region, with a configurable
+  "favorite region" core option (EU/US/JP/TW). The ZIP must contain
+  at least one of the BIOS blobs listed below. ST-V games are detected
+  automatically when loading a .zip file.
+
+  BIOS loading: libretro.c retro_load_game() lines 1601-1727.
+  STV blob table: ctrl/src/stv.c BiosList lines 112-136.
+  Region enums: ctrl/include/stv.h lines 47-52.
