Please add more info about your system, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

When you configure your controller, as detailed in the Docs, RetroPie will create automatically a controller configuration for RetroArch, so you shouldn't need to configure it manually there.

@polygonman244 Hey, there. I know this goes back a year, but emulationstation does not detect my PS Classic controller on the latest version of Retropie on a Pi4 ("no gamepad detected" after boot) and I'm just hoping you can please elaborate on what you meant by "I just used the 'map controller' setting and it worked." Do you mean the Configure Input screen after you press start in emulationstation with a recognized controller? Or is there another way to map a controller that I've missed?

Thanks for any help!!

@Mondo-Gecko

I've never tried using Bluetooth controllers, but I'll give it a shot and check what happens. I don't have access to my Raspberry Pi until at least the end of next week though.

@edmaul69 alright tnx guys i attempted this and it work :) tnx for the help guys i guess i didn't clean it well the first time

@Mr_Fix_It Thanks sooo much for this man I've been pulling my hair out for days with these bloody controllers. :)

@TMNTturtlguy in Configuration Editor, choose Configure basic libretro emulator options, Configuration default options or from a specific emulator, then Choose joy pad order.

@backstander @OreoLover Or you can use @meleu 's excellent tool that already do this without ever needing to go in to the Retroarch controller configuration.

You can find it here

@julijan Email me at holco zero zero four @umn.edu (change to numbers and get rid of spaces) and I'll give you details - thanks!

Thanks for all the help.

I decided to just add OEM NES ports as it turned out to be one of the cheapest options sans changing out the cords on an OEM NES controller.
