+notes: |
+  Side-scrolling 1995 action game by Crack dot Com, SDL2 fork from the Xenoveritas
+  branch. The port ships its own game data in-tree under data/ (14 MB), including
+  the Lisp scripts, levels, art and freedesktop metadata; the fRaBs expansion was
+  removed from this fork over licensing uncertainty.
+
+  Entry point abuse.lsp is loaded relative to the data directory. The data root
+  is set in src/sdlport/setup.cpp:
+    1. -datadir <path> CLI argument (setup.cpp:327-332)
+    2. datadir= in abuse.cfg (setup.cpp:182)
+    3. ASSETDIR compile-time constant, filled by CMakeLists.txt:45-54 — "." on
+       Windows, abuse.app/Contents/Resources/data on macOS, share/games/abuse on
+       Linux (setup.cpp:441-474)
+  Loader1 reads abuse.lsp via lisp (loader2.cpp:284), which chain-loads
+  lisp/english.lsp -> lisp/common.lsp -> lisp/startup.lsp -> ...
+
+  Batocera's packaging (package/batocera/ports/abuse/abuse.mk) pins DASSETDIR to
+  /userdata/roms/abuse and splits the data into the Pacman package abuse-data
+  which pulls abuse.zoy.org's abuse-data-2.00.tar.gz, a 16 MB public-domain pack
+  that includes music/ and sfx/ (which the Xenoveritas tree omits).
+
+  No separate BIOS or firmware. The whole game is open content.
