+emulator: Beetle Saturn (Mednafen)

+
+notes: |
+  Beetle Saturn is the libretro port of Mednafen's Sega Saturn emulation module.
+  Two region-specific BIOS files are used: sega_101.bin for Japan/Asia NTSC,
+  mpr-17933.bin for North America, Europe, and all other regions. The core
+  returns false from InitCommon() if the BIOS file is missing or not exactly
+  512 KB, so both BIOS files are required for full region coverage.
+
+  Region auto-detection reads the disc header and picks the matching BIOS.
+  Manual region override is available via beetle_saturn_region core option.
+
+  The KOF95 and Ultraman ROM carts are optional game-specific expansion
+  cartridges loaded from the system directory. The Action Replay 4M Plus
+  cart (satar4mp.bin) is listed but marked unfinished in source (needs
+  CPU UBC emulation).
+
+  BIOS loading: mednafen/ss/ss.cpp InitCommon() lines 920-961.
+  Cart loading: mednafen/ss/cart.cpp CART_Init() lines 128-220.
+  Firmware path: libretro.cpp MDFN_MakeFName(MDFNMKF_FIRMWARE) -> system dir.
+  Default cart ROM filenames: mednafen/settings.cpp MDFN_GetSettingS().
