The X, O, Square, and Triangle buttons can be confusing to map because they are referred to as buttons A, Y, Triangle, and Square by RetroArch. Here is an image showing the DS4 button numbers.ĭual Shock 4 button mappings and names for RetroArch. Input_device = 'Sony Computer Entertainment Wireless Controller' The 元 button, identified as input_l3_btn is assigned the value 10. Here is what the DS4 controller configuration file looks like. Sony Computer Entertainment Wireless Controller.cfg Listing You will see input_l3_btn = “10” that says, “the DS4 元 button is identified as button 10.” In RetroArch, you would then use the value “10” to specify to map 元 to a function. If you need to find out “What is the button number for 元?” then looking at this file will help. For the Dual Shock 4, this file is, /opt/retropie/configs/all/retroarch-joypads/Sony Computer Entertainment Wireless Controller.cfg Each type of controller connected should have its own configuration file located in /opt/retropie/configs/all/retroarch-joypads. Dual Shock 4 Controller Configuration FileĪ special configuration file associates button numbers with their intended functions. It makes it easier to navigate RetroArch and EmulationStation without having to rethink different button mappings for both programs. For example, if the DS4 X button means “Select” and Square button means “Back” in EmulationStation, then use X and Square for Select and Back in RetroArch as well. Map the buttons so that their actions match those of EmulationStation as much as possible. If you make a mistake, you can always re-run the button mapping. On the Dual Shock 4 controller, lightly– LIGHTLY- press the L2 and R2 trigger buttons or else they will double map or skip. To get started, choose “ User 1 Bind All.” Press a controller button at each prompt that appears to map a button to a specific function.

In EmulationStation, go to the Retropie menu and choose “ Configure RetroArch / Launch RetroArch RGUI.”Ĭontroller configuration for controller 1, called “User 1” in RetroArch. RetroArch Controller ConfigurationĪ keyboard is recommended, so be sure to connect a USB keyboard to the Pi since we will be configuring RetroPie locally, not remotely through SSH. RetroArch still needs its own fine-tuning. RetroPie 3.5 tries to duplicate the EmulationStation controller settings to RetroArch for you automatically, but I have found that it is not perfect. The controller setup first performed by EmulationStation only affects EmulationStation. These two programs require individual controller set up. Once you pick a game you want to play, control passes to RetroArch (or a standalone emulator), which starts the actual playing. Analog Buttons, Touchpad, and the PS ButtonĮmulationStation and RetroArch are two separate programs.Sony Computer Entertainment Wireless Controller.cfg Listing.
