Plug and play with a new controller, without keyboard and mouse access needed for configuration and mapping.With RetroArch joypad auto configuration system, your joypad will be recognized and will work out of the box. Manual mapping as with standalone emulators is always an option, however! Benefits

The difference is that RetroArch begins by detecting your controller and automatically configuring it if possible. For example, this is how the OpenEMU controller configuration looks: Standalone emulators let you map each of your controls to the original controller for the emulated system. And these input systems differ widely in the way they enumerate the pad buttons. Each of these platforms have one or more input systems. RetroArch works on a lot of different platforms. The autoconfig profile with the highest score is used to map the controller. We compute a matching score for each configuration file based on these three factors. The vendor id and product id pair is often abbreviated as vid:pid. Matching is done using 3 criteria: the device name, the vendor id and the product id. Depending on your platform, these autoconfig profiles are either distributed with RetroArch or downloaded through the Online Updater.
