It seems like the Retro Receiver by 8Bitdo plays nice with a fair selection of bluetooth controllers. Would it be possible to modify USB controllers/arcade sticks with Bluetooth and pair it with the RR? I'm willing to go as far as using a Teensy or PiZero. Anyone have any insight on this idea?
Related: Same question, but with wired SNES accessories. Can we make a normally wired SNES add-on wireless, this way? I've seen some homebrew methods, but I'm not familiar with the details.
