+Libretro is a simple but powerful development interface that allows for the
+easy creation of emulators, games and multimedia applications that can plug
+straight into any libretro-compatible frontend. This development interface is
+open to others so that they can run these pluggable emulator and game cores
+also in their own programs or devices.
+
+This core is based on the Nestopia UE (Undead Edition) Nintendo Entertainment
+System emulator.

+retroarch normally expects to find the NstDatabase.xml file in
+~/.config/retroarch/bios, but there's no real reason to be editing it.
+Rather than have users manually copy the file into place, we install it
+system-wide and look for it there instead.
