+notes: |
+  The open source continuation of the Super Mario War fan game. The code and
+  the game data live in two repositories: the engine reads graphics, sounds,
+  music, maps, worlds and tours from a data directory, ./data beside the
+  executable unless --datadir names another. A graphics or sound file missing
+  from the selected pack falls back to the Classic pack, and missing menu fonts
+  or start graphics stop the game at its splash screen.

+  EmuELEC builds this revision with a patch moving the configuration to
+  /emuelec/configs/smw. Its run_smw.sh fetches mmatyas/supermariowar-data at
+  da13a367 into /storage/roms/ports/smw/data on first start, when
+  worlds/Big JM_Mixed River.txt is absent, and passes that directory as
+  --datadir.
