dbar4gun: new Wii remote userspace driver as lightgun

mitu

@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 ?

mitu

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

Are you fully up-to-date ?

Chef Otis

@mitu Yessir, always up to date and official

mitu

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

Chef Otis

@mitu ah yes, I see it now

The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

apt-get install python3-venv

You may need to use sudo with that command. After installing the python3-venv

@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 ?

Chef Otis

@mitu

pi@retropie:~ $ locale -a
C
C.UTF-8
en_GB.utf8
POSIX

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.
