Use your 3DS as a networked webcam with this homebrew (and a nifty python script)
Uses the sounddevice, qoi, and pyvirtualcam pip packages, which require you to have OBS and VoiceMeeter installed.
On Windows, at least. If you use any flavour of *nix, you should know enough to make it work.
To run, you must have OBS studio with virtual cam and run this in a command prompt:
pip install sounddevice, qoi, pyvirtualcam
This fork will now be used for uploading builds due to the original repo not having releases.
Launch the 3DSX from the Homebrew Menu on your console, set it up how you want (microphone/camera/both)
Start the connection
Run the script with your console's IP address as the only command-line argument
When you want to stop, stop the connection on your console or exit directly.
