Its not removing any configuration the devices are named the same what you need to to is wire them up the same and you only need to set it one time will work for both players as its configured per device.
So what you are saying is that I need to hookup the buttons on each controller so that they are the same value. IE button 1 for each controller is ''A''. I never had this problem before but will just rewire my board to make sure they match.
Trying to set up version 2 of this Raspberry Pi - everything is the same as the one discussed above, image from v1 copied and then written to a second SD card and inserted into a second Pi 3B+
As I start it up I'm getting the usual "no gamepad detected" which is fine, I'll live with it, but on v2 only, when I try to map a pad (in this case a second Mega Drive replica, and a brand new out of the box second Mega Drive replica) I cannot map any buttons other than Up, Down, Left, Right, Start and Select.
When I get to button A, I have no response whatever. I thought it might be a faulty controller, but as I've said, also tried it with a one I know works on the original system and get the same issue.
Try rewriting the SD card? Anyway to skip button mapping completely? Something else to try?~~
Ignore. Got it working by changing the input mode of the pad from X input to D input
