      Hi !

      So I bought this Retrofit Gamecube USB controller. It's this one : https://www.amazon.ca/-/fr/RET00068/dp/B074CPY67J
      I can't find it on Retro-bit web site... which is weird, but ok why not.

      When I try to configure the gamepad on Recalbox, and/or directly in Dolphin, I can map every button, except the C-stick left/right. I tried to plug the controller on my Mac and the C-stick button seems to be working. I even tried to edit the GCPadNew.ini file but it's not working. It appears the c-stick left/right is just not working on Recalbox or Linux.

      It's annoying because I obviously bought this controller specifically to play Gamecube games on the Recalbox 😕
      I don't know if the C-stick is really needed on much games, but still.

      Anyone has an idea to help me there ?
      I'm still searching, but I don't know what to do now I can't even find the controller on Retro-bit web site...

          Hi !

          Thanks for your answer. I took a look at the links you posted but it was not really helpful. (FYI, I posted the first one 😛 )

          So I went and did more research yesterday. First, when I do a jstest, I can see all button or axes are working, but not the C-stick left/right. And I know because I test all stick, that the c-stick left/right should be axe 2. But nothing is happening when I move the c-stick on that axis.
          000.png

          I tried the gamepad on MacOS and Windows and the c-stick is working fine on every axis. So we can assume the gamepad is not broken or something like that. It has to be with the driver or the way Linux/Recalbox read the device.

          Let's try if we can read the device.

          First, let's find out where events for that device go :

          # ls -lattr /dev/input/by-id/usb-0079_Generic_USB_Joystick-event-joystick 
lrwxrwxrwx    1 root     root            10 Jan 23 19:54 /dev/input/by-id/usb-0079_Generic_USB_Joystick-event-joystick -> ../event10

          Now we can read the device :

          # hexdump /dev/input/event10

          I got a lot of events, even if I'm not pressing any buttons on the gamepad.

          For comparaison, here's what I got with an other gamepad (everything is ok with this one) :

          # hexdump /dev/input/event2

          I got nothing until I really press something on the gamepad.

          If I do an evtest for the Gamecube USB controller :

          # evtest

          Again, lots of stuff even I don't even touch the controller.

          Now the evtest with my other gamepad :

          Once again, nothing until I press something on the gamepad.

          Here I am right now... I guess it's weird that the faulty gamepad is generating that much events... or maybe not.

            Ok I think I might know why the usb gamecube controller is generating that much event. The axe #2 (yes, the c-stick left/right) is "shaky", meaning that the value keeps changing when I do nothing on the gamepad. But its osclillating between 127-129. And when I move the stick left or right, it doesn't change anything.

              Ok...

              So it's not the c-stick that is causing all the events, it might be the main one. When I put the main stick all to the left, events stop generating. But those events were for the c-stick. It's really weird.

              I also tried to cat the file for the device (/dev/input/js1) and even there, when I move c-stick left/right, nothing change. But it does for other buttons. So now I think unless I can install new drivers it's a lost cause. If I can't find a driver for this, I'm gonna return it.

              I see those problems as challenges but I also just want to play Gamecube 😄

                Normally this is not possible, a regular user cannot install anything in Recalbox.

                  @zing said in Retrobit Gamecube controler : C-stick not working:

                  Normally this is not possible, a regular user cannot install anything in Recalbox.

                  hmm ok... too bad.

                  Anyway I tried Batocera, to see how this one handles the gamecube controller. Well, the controller works perfectly on Batocera. The C-stick is working. Unfortunately, I was unable to configure a specific config file for Gamecube as I did with Recalbox. I'm back on Recalbox now.

                  So, after all that, I forfeit. Too bad for that controller, I won't use it. I might look for an other one, better, more compatible. Maybe the one for the Nintendo Switch, it would be nice to use it Bluetooth.
