      @cnoto Do you have the Pi in a case ? Is there anything around it that may cause interference ?

        @mitu The pi is not currently in a case. I haven’t had an issue like this before and built quite a few setups using bluetooth controllers in this location. The controllers both work fine on their own. The issue arrises when they are used at the same time.

          @mitu Is the processing for adding controllers different when connects the first time via the Bluetooth menu vs connecting via a udev rule? The first works fine and the second is where the issues are coming.

            @cnoto The udev rule kicks into place after a connection to the device is made and the device is added to the system, it doesn't have any influence on the quality or establishment of the connection.

              @mitu It looks as if controller two is taking over for controller 1. Is there a way to change the name of a controller within retropie to ensure they are read differently.

                No, naming is assigned based on what the controller reports - at the OS (Linux) level.

                  I tested the same controller setup with a pi3A so I have confirmed that the controllers are working properly. It seems to be an issue with the pi0w as both I have on hand had the same problem. I will rethink my genesis focused build to leverage the 8bitdo mod30s on a pi3A instead.

                  The question is - do I leverage a Genesis cartridge as the case or some sweet colorful nes carts I just picked up. I would need a label for the genesis cart. Let me know if anyone knows of a place to get a custom genesis cart label (preferably that fits on an EA sized game).
