Bloopair allows connecting controllers from other consoles like native Wii U Pro Controllers on the Wii U.
It temporarily applies patches to the IOS-PAD module responsible for Bluetooth controller connections.

• Connect up to 7 controllers wirelessly via Bluetooth
• Rumble support
• Battery levels

• Nintendo Switch Pro Controller
• Nintendo Switch Joy-Con
• Nintendo Switch Online SNES / N64 Controller
• Microsoft Xbox One S/X Controller
  Note: The latest firmware versions and all Series S/X Controllers are currently not supported due to missing Bluetooth LE support.
• Sony DualShock 3 Controller
  To pair a DualShock 3 to the console, see the Pairing a DualShock 3 section.
• Sony DualShock 4 Controller
• Sony DualSense Controller

• Download and extract the latest .zip from the releases page.
• Copy the 30_bloopair.rpx from the .zip file to the modules/setup/ folder of your target environment on the SD Card.
  This would be wiiu/environments/tiramisu/modules/setup/ for Tiramisu.
• Copy the wiiu folder from the .zip and copy it to the root of your SD Card.
  If you're using aroma you can delete the Bloopair_pair_menu.rpx in the wiiu/apps folder and use the .wuhb instead.

Make sure you're using Tiramisu or Aroma. Follow https://wiiu.hacks.guide/#/ to setup Tiramisu.
More info about Tiramisu here: https://maschell.github.io/homebrew/2021/12/31/tiramisu.html

• Once you're booted into Tiramisu and are in the Wii U menu, press the SYNC button on your console and controller.
• Wait until the Controller is connected.

If a controller had been paired in the past, simply turn it on again and it should reconnect.

The DualShock 3 needs to be paired using a USB cable. After the initial pairing it can be used like any other wireless Bluetooth controller.

• Open the Bloopair pairing app from the Wii U menu or Homebrew Launcher. You should now be in the USB pairing menu.
• Connect the DualShock 3 using a USB cable to the front or back ports of the console.
• The screen will say "Paired!" once the controller has been successfully paired.
  You can now remove the USB cable from the controller. Press the PS button once back on the Wii U menu to connect it to the console.
• Press the HOME button to exit.

The DualShock 3 is now ready to use with the console.

Make sure Bloopair is running and both the console and the controller are in SYNC mode.
Also make sure the controller is on the supported list.
Wait for about a minute, and if nothing happens restart your console and redo the process.
You can also try clearing controller syncs.

Possibly, I've for now added support for all the controllers I currently own. Maybe I can get a few more controllers which I could add support for.
Pull requests for different controllers are always welcome.

• Support more controllers
• Bluetooth LE support (Unlikely, only partially supported by the Bluetooth Stack)

Bloopair will patch the IOSU's IOS-PAD module in memory. It will make sure any bluetooth peripheral can be paired to the console.
Once paired and connected it will convert received HID reports to the Pro Controller HID report format, which padscore expects.
