+# This configuration is for when the controller is connected by 2.4GHz dongle.
+# When connecting via USB, the controller presents as Xbox 360 Controller.
+# The controller presents the same IDs as
+# ../udev/SEGA_Mega_Drive_Mini_6B_Controller.cfg but it runs different driver.

+# The RetroPad layout has four face buttons, whereas the M30 has six. We map
+# the M30's L and R buttons to the RetroPad's triggers, and map the M30's Z and
+# C buttons to the RetroPad's left and right shoulder buttons respectively.
+# That may seem somewhat counterintuitive but it follows the convention that is
+# used in many cores for systems that have six face buttons in this layout.
+# That allows the controller to be autoconfigured and work in the natural way
+# in the Beetle Saturn core, and in 6-button fighting games in the
+# FinalBurn Neo and MAME cores.
