List of No-Crosshair
I am looking for people who can help me test and try out games to complete the following list:

@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 ?
-
@mitu it gives me this error:
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:

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simpleOK, 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 ofdbar4gun.shwhich you can replace the$RetroPie-Setup/scriptmodules/supplementary/dbar4gun.shand re-try the installation. Make a backup of$HOME/RetroPie-Setupfirst, 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.

I get the same errors as @RynoRoe , just on a rpi4 4.8.9
Are you fully up-to-date ?
-
@mitu Yessir, always up to date and official
-
@Chef-Otis Please post the exact error message. The latest version shouldn't have that error anymore.
-
@mitu ah yes, I see it now

@Chef-Otis you have the latest version indeed, bu the error is puzzling since the package's dependencies specifically install
python3-virtualenvandpython3-dev. I can't reproduce it here.What's the output of the
locale -acommand ? Did you change the system/user language ? -
pi@retropie:~ $ locale -a
C
C.UTF-8
en_GB.utf8
POSIXthis 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.
