+# Daphne custom keyboard mapping
+#
+# Any inputs defined below will map keyboard keys to
+# Daphne input, regardless of remapping that occurs in emulationstation.
+#
+# Each input is mapped to 2 keyboard key codes (or 0 for "none")
+#
+# Find keyboard codes here:
+# http://www.daphne-emu.com/mediawiki/index.php/KeyList
+#
+# Example: Quit will always be key [Esc] or [Q]
+# KEY_QUIT = 27 113
+#
+# (Place all entries after [KEYBOARD])
+
+[KEYBOARD]
