+notes: |
+  Open-source port of E. Hashimoto's 2008 Japanese freeware Metroidvania Hydra
+  Castle Labyrinth. ptitSeb's SDL/SDL2/SDL3 fork is used by batocera (the
+  package batocera/ports/hcl pins HCL_VERSION to this commit).
+
+  The engine opens every data file from a relative "data/" prefix hard-coded
+  in the sources:
+    - qda.c:19   — strcpy(fullPath, "data/") before appending qda chunk names
+    - hero.c:202 — fopen("data/save.tmp", "rb")
+    - sdl2/audio.c:30 — strcpy(buff, "data/") before midi/wav loads
+    - sdl2/graphics.c, sdl3/graphics.c — fopen("data/bmp.qda", "rb")
+    - game.h:184 — savename macro = "data/save.tmp"
+  Save files are rewritten in that same relative data/ tree, so the game must
+  be launched from a working directory that contains data/ (batocera copies
+  the shipped data/ beside the binary).
+
+  The 31 MB data/ tree is shipped in the source repository and is open content.
+  Nothing else is required.
