I have never bought a bluetooth game controller before.
I found this guy on Amazon: [2020 Upgraded Version] Wii U Pro Controller Wireless Controller Gamepad Bluetooth Game Controller Joystick for Nintendo Wii U with USB Charging Cable…
Unfortunately I’m having some trouble getting the Pro+ to work with Plex Arcade. It seems the d-pad doesn’t function at all…obviously an issue with SNES games.
