If you accidentally pressed the 'B' button with a value of '2' during setup when it prompted for 'A,' then it would be recorded into the config file as input_a_btn = '2', so if you want to jump in Super Mario Bros., you would have to press 'B' on your controller. pressing the 'A' button will tell RetroArch to press the 'A' button on its RetroPad, causing Mario to jump. Therefore, the next time you play a game such as Super Mario Bros. Pressing the 'A' button would then record into the config file as input_a_btn = '1', so RetroArch will know that the 'A' button on your physical controller corresponds to the 'A' button on RetroArch's virtual controller, the RetroPad. When setting up the controller in EmulationStation, these values are then assigned a respective action on RetroArch.ДЇor example, suppose the 'A' button on a USB SNES controller has a value of '1.' When setting up the controller, EmulationStation would prompt you to press the 'A' button on your controller. This is an example config for a USB SNES controller input_device = 'USB gamepad 'ДЄs seen above in the config for the USB SNES controller, each input on the controller has an associated value. Each emulator page on the wiki has a diagram of the original controller for its respective console that will correspond to the same inputs listed below.ДЄfter you've configured your controller the autoconfig will be created here: /opt/retropie/configs/all/retroarch/autoconfig They can be used as a reference when configuring your controllers. The following diagrams are for the 3 most common controllers: Super Nintendo, Xbox 360, and PlayStation 3. You'll know if your controller has been automagically configured if you see a flash of yellow text on the bottom of the screen with your gamepad ID when you start a game. Your joypad is automagically configured for libretro (RetroArch) emulators when you configure your controller in EmulationStation. You can also access it from the start menu within EmulationStation under the Configure Input option. RetroArch controls have been integrated into EmulationStation and will be the first thing you see when you boot from the RetroPie SD image the first time.

Core Input Remapping - an easy way to do specific control configurations for specific cores, made in the RetroArch RGUI.

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.ДЄs 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.ДЇor 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.
