      @lowlevel1989 this no longer seems to install from the retropie script module. How can I get this to install on my retropie setup?

        @RynoRoe What errors do you get when installing the package ?

          Could not successfully install dbargun - dbargun is a Linux userspace driver for the wiimote with DolphinBar support.
          (opt/retropie/supplementary/dbar4gun/bin/dbar4gun not found).

            The previous messages are showing the actual error. Try to post them also, along with the your setup info as requested in https://retropie.org.uk/forum/topic/3/read-this-first.

              @mitu ok I’m running the newest install of retropie on a pi3 while running usb rom service with all my roms on an external drive. Here is the log file text:

                OK, I see the error. Should be fixable - I'll take a look at it.

                EDIT: it seems the new code is not compatible anymore with RaspiOS Buster and needs Python 3.8 as a minimum.

                @lowlevel1989 we can install the 0.13 version for older RaspiOS, before the calibration code was added - is that ok ?

                  @mitu so does this mean I need to somehow install an older version of dbar4gun?

                    @RynoRoe At the moment, yes.
                    You can try this version of dbar4gun.sh which you can replace the $RetroPie-Setup/scriptmodules/supplementary/dbar4gun.sh and re-try the installation. Make a backup of $HOME/RetroPie-Setup first, before replacing the file, and restore it afterwards.

                      Hi, im really curious about this and wanting to try it out. If i understand correctly this will enable you to use two lightguns simultaneously? I have retropie setup on a Pi400 which only has 3 USB ports, and all mine are currently in use (2 controllers+ mouse). Would this work with the Dolphinbar connected through a USB dongle?
                      @RynoRoe did you get this working with the older version ?

                        @RynoRoe the installation should work now without futher modifications, just update RetroPie-Setup and re-try the installation.

                                @Chef-Otis Please post the exact error message. The latest version shouldn't have that error anymore.

                                    @Chef-Otis you have the latest version indeed, bu the error is puzzling since the package's dependencies specifically install python3-virtualenv and python3-dev. I can't reproduce it here.

                                    What's the output of the locale -a command ? Did you change the system/user language ?

                                      this is what I get with that command. I don't think I've change any sort of system/user language..

                                      After applying apt-get install python3-venv I was able to install dbar4gun successfully, but I still can't actually get the wiimote working.

                                        @Chef-Otis, have you followed the steps in the README? Were you able to start the service, or what issue are you facing exactly?

                                        I usually respond faster when the error is reported through this channel: GitHub Issues.
