+emulator: Daphne
+type: libretro
+source: "https://github.com/libretro/daphne"

+
+notes: |
+  Daphne is a LaserDisc arcade game emulator ported to libretro. It emulates
+  classic full-motion video arcade games like Dragon's Lair, Space Ace,
+  Cliff Hanger, and others that used LaserDisc players for video output.
+
+  The core does NOT require any shared system BIOS or firmware files.
+  The libretro-core-info file (daphne_libretro.info) declares no firmware.
+
+  Each game loads its own arcade ROM set from a ZIP file named after the game
+  short name (e.g. lair.zip, cliff.zip, bega.zip). ROM files are individual
+  arcade chip dumps loaded via the rom_def struct in each game class
+  (daphne-1.0-src/game/*.cpp). CRC32 verification is performed at load time
+  (game.cpp:769-778).
+
+  Content loading path (libretro.cpp:546-637):
+    1. User points RetroArch to a .zip file (e.g. /Daphne/roms/lair.zip)
+    2. The core strips the path to derive:
+       - rom_name: game short name (e.g. "lair"), lowercased
+       - rom_path: parent directory
+    3. A home_dir is set to rom_path/.. (one level up from roms/)
+    4. Additional data is expected relative to home_dir:
+       - roms/    -> game ROM ZIPs
+       - framefile/ -> frame description files (.txt)
+       - sound/   -> sound samples
+       - ram/     -> SRAM saves
+       - pics/    -> overlay graphics
+
+  Expected directory layout:
+    Daphne/
+      roms/lair.zip
+      roms/cliff.zip
+      framefile/lair.txt
+      framefile/cliff.txt
+      sound/lair/   (optional, game-specific samples)
+
+  Supported games include (from README.md and libretro.cpp):
+    lair (Dragon's Lair), ace (Space Ace), cliff (Cliff Hanger),
+    bega (Bega's Battle), badlands (Badlands), esh (Esh's Aurunmilla),
+    interstellar, mach3, sdq (Super Don Quix-ote), tq (Thayer's Quest),
+    astron, galaxy, cobra, roadblaster, gpworld, lair2 (Dragon's Lair II),
+    and many ROM revision variants.
+
+  The core is marked experimental. Savestates, cheats, and disk control are
+  not supported. Requires full file path (retro_load_game uses path, not
+  data buffer).
+
+files: []
+  # No shared BIOS or firmware files. All ROMs are per-game arcade chip
+  # dumps distributed inside game-named ZIP archives. These are game content,
+  # not system files managed by retroarch_system.
