Setup
Download the latest version of Santroller.
After downloading Santroller, open “SantrollerConfigurator”.
Hold the “Boot” button on your Adafruit Feather RP2040 with USB Type A Host if you’re plugging it into your computer for the first time.
In SantrollerConfigurator, set “Input Type” to “USB Adapter.” The Adafruit Feather RP2040 with USB Type A Host should be detected as “Raspberry Pi Pico.” Click “Configure” after doing this.
Give it a moment to program initial configuration. When prompted, click on “Configure” again.
After you’ve loaded into the configuration page, scroll down to the “Presets” section and click to expand it. Once expanded, click on “Import Settings from File”
A community made preset exists (courtesy of jnack) to help speed things up. Load it up via the “Import Settings from File” option.

After loading the preset, MAKE SURE YOU CLICK ON “Save Settings” before closing the program or you will lose progress!

Additional Notes
The picoconfig preset binds a few things for a better experience with a PS4 Riffmaster.
- The “Boot” button on the Adafruit Feather RP2040 with USB Type A Host will act as a guide button as pressing and holding the guide button on the Riffmaster shuts it off.
- D-Pad: Left and Select are swapped as the PlayStation Riffmaster. This is because, by default, the PlayStation Riffmaster has Overdrive activation bound to D-Pad Left which is very uncomfortable.
If you wish to remove these tweaks, click the “Remove” next to the D-pad Left and Back buttons at the bottom of Santroller Configurator.
After that, go to the “Usb Host Inputs” section and enable the original buttons again.
