+* This game has no subtitles. (https://www.vogons.org/viewtopic.php?f=32&t=86635)
+* The lack of the flashing effect when taking a photo is accurate. The game behaves this way on hardware, as well. (https://www.vogons.org/viewtopic.php?p=1052487#p1052487)
+* The awful borders around the crank and box overlays in the hardware store are also accurate. (https://www.vogons.org/viewtopic.php?p=1052487#p1052487)
+* When the Guardian disappears, the background appears far before the overlays fade in. This is also accurate. (https://www.vogons.org/viewtopic.php?p=1052487#p1052487)
+
+
+# Lord of the Rings
+
+
+* Hitting space+esc locks things up real good.
+* Loading the demo on the title screen gives a "FMPOpen Error Code: 0" error message (https://www.vogons.org/viewtopic.php?p=1049075#p1049075)

+Game bugs that are known to exist in both this emulator AND that also happen
+wich a real hardware setup are documented in the `KNOWN_GAME_BUGS.md` file.
