ArcadeHub Mini

Use any bluetooth gamepad on your Nintendo Switch or Nintendo Switch 2 with a Raspberry Pi Pico 2 W.

List of supported controllers

This project is possible thanks to Bluepad32 and TinyUSB. This project is a fork of PicoSwitch-WirelessGamepadAdapter

Multiple gamepads support (4 max)

Updates from PicoSwitch-WirelessGamepadAdapter

• Outputs to Switch as a Pro Controller

  • Please note that by connecting your controller this way it will disconnect from the adapter and sync with the Switch natively so the adapter is no longer being used and will automatically pair wirelessly without using the adapter again
  • Tested working with Wii U Pro Controller
  • PS5 controller does not pair back wirelessly unless you disonnect the adapter after its synced
  • Testing more controllers

• Corrected Wii U triggers so that they register properly

• Corrected Wii Gamepad L/R and triggers so that they register properly

• Added buttonn command of pressing +/- or Start/Select equivalents to disconnect the controller from the adapter (doesnt work on Switch because the switch will just switch to its own bluetooth instead of communicating via the adapter)

• Please note that the adapter currently crashes the Nintendo Switch 2 after enabling the device to output as a Switch Pro Controller!

Installing

1. Download latest .uf2 file
2. Plug Pico on PC while holding the bootsel button.
3. A folder will appear, drag and drop the .uf2 file inside it.

Building

1. Install Make, CMake (at least version 3.13), and GCC cross compiler

   sudo apt-get install make cmake gdb-arm-none-eabi gcc-arm-none-eabi build-essential

2. (Optional) Install Pico SDK and set PICO_SDK_PATH environment variable to the SDK path. Not using the SDK will download it automatically for each build.
3. Update submodules

   make update

4. Build

   make build

5. Flash!

   make flash

   This make command will only work on OSes where the mounted pico drive is located in /media/${USER}/RPI-RP2. If this is not the case, you can manually copy the .uf2 file located inside the build directory to the pico drive.

Other make commands:

• clean - Clean build directory.
• flash_nuke - Flash the pico with flash_nuke.uf2 which will erase the flash memory. This is useful when the pico is stuck in a boot loop.
• all - build and flash.
• format - Format the code using clang-format. This requires clang-format to be installed.
• debug - Start minicom to debug the pico. This requires minicom to be installed and uart debugging.

Development roadmap

• Implement Mode Switching to PS3
• Implement Mode Switching to Wii U
• Implement Mode Switching to Wii
• Implement Gamecube Controller output
• Implement PS2 Controller output
• Implement OG Xbox Controller output
