Run the update.bat file to detect and update the Bluetooth pinball controller. The included firmware.bin is the alternate swapped version with flipper in the front and nudge in the back. If you want to go back rename firmware.bin.orginal to firmware.bin and run update.bat again.

There are a collection of remap files for Retroarch for classic games configured for these controllers. Copy the remaps folder into the Retroarch\config folder like this "D:\LaunchBox_pinball\Emulators\RetroArch\config"  I have a Batocera and a Launchbox/Retroarch build setup for these controllers available to download serparately.
