@notthesame i got a fix which works, i use a m30 and Start and B and than plug in this is for Dinput for standalone emulators and will keep gamepad active and i can now set out.

This should work for any other 8bitdo

Thanks again😃✌

@bradbradbrad hmmm, I will have to procure that UB400 and experiment! Thanks for the tip!

@alphabetapie

Do you only ever have one type of controller plugged in, and only using retroarch cores?

If yes, then you could use the EmulationStation input configuration to set up the M30 to match Sega Genesis (or whatever), and then create a core remap file in the retroarch RGUI > Input settings to swap any buttons as needed in the other cores. You could use even use game remaps if you need to.

It is also possible, but more manual effort, to put different configurations in different directories, and then use the retroarch.cfg joypad_autoconfig_dir setting to point different cores (or even games) at different controller configurations.

joypad_autoconfig_dir = "/opt/retropie/configs/snes/joypads/"

@notthesame I can't believe that worked, you are a godsend. I'd also like to add a few details:

After pressing Start and Y, the LEDs start to rotate from left to right. After that, you hold pair for 2 seconds, the LEDs go off for a second, and then they start to rotate again.

At this point you need to go through the Bluetooth pairing process again (and if your controller is already paired, you should un-pair it before you re-pair it) but you do NOT need to set up the udev rule. All you need to do is reboot and configure the input like normal.

I think this should be added to the documentation.
