Hardcoded Configurations - made by editing retroarch.cfg file(s).Autoconfigurations - made in EmulationStation.There are 3 main ways to configure input for RetroArch: If you wish, you can reconfigure this control mapping, either for all RetroArch, for a specific system, or even for a specific ROM. The mapping for many consoles is represented by the pictures below and on each system's wiki page. If your real controller has less buttons than a DualShock, then the virtual RetroPad also has less buttons, that's perfectly fine.Īs RetroArch starts an emulator core, it maps the RetroPad configuration to the emulated system's original controls.

You don't have to map all of the RetroPad buttons to a real world button. A RetroPad has an ABXY layout like a SNES controller plus four shoulder buttons and dual analog sticks like a Sony DualShock. A RetroPad does not exist in real life, it's a concept only within RetroArch.

RetroArch controls map real-world controller buttons to a virtual controller called a 'RetroPad'. When you configure your controller in EmulationStation, the RetroPie setup script automatically configures RetroArch with the same controls. This allows a specific setting or button mapping for a certain console or even just for a certain game.įor emulators which are not libretro cores, there are emulator-specific configurations under the respective system's wiki page. However, RetroArch also provides the freedom to configure specific emulators individually and even individual games differently if the user wants. RetroArch and libretro provide ability to configure controllers once for many emulators instead of having to configure each emulator individually. For example, lr-snes9x2010 is the libretro core of the SNES emulator called snes9x2010. In RetroPie, the libretro emulator cores are identified with a lr- in front of their name. With a few simple changes to the emulator source code, almost any existing emulator could become a libretro core. RetroArch then handles the input (controls) and output (graphics and audio) while the emulator core handles the emulation of the original system. RetroArch and libretro provide a way to take an existing emulator and load that emulator as a library or 'core'. RetroArch is the official front end for the libretro API.
