+      This is a port of Ryan Dywer's decompilation of classic N64
+      shooter Perfect Dark to modern systems.
+
+      You will need to provide a copy of the ROM at
+      `$HOME/.local/share/perfectdark/data/pd.${romID}.z64` to launch
+      the game.
+
+      Though `ntsc-final` is the recommended default, you can change
+      the ROM variant of this game with an expression like this:
+
+      ```nix
+        perfect_dark.override { romID = "jpn-final"; }
+      ```
+
+      Supported romIDs are `${lib.generators.toPretty { } roms}`.
