-   "Libretro uses a virtual gamepad abstraction known as the 'RetroPad' to communicate from frontends (like RetroArch) to cores and vice versa. While there is no actual, physical RetroPad device, it can be helpful to think of it as looking like a modern controller with four face buttons in the usual diamond configuration--with Y on the left, B on the bottom, A on the right and X on top, a directional pad, four shoulder buttons--R1, L1, R2 and L2--two analog sticks that can be pressed to trigger additional digital actions--R3 and L3--and two additional buttons for 'start' and 'select'. If a physical input device is recognized and autoconfigured correctly, users probably do not need to use this menu at all, and for core-specific input changes, should use the Quick Menu's 'Controls' submenu instead."
