Chainbrian uses the NON GUI version. I got that version working as well. ---> https://github.com/kokolihapihvi/RockSniffer/releases/
you can use it in a web browser page to display it for yourself if you wanted to. Put the same path to the file in your address bar in a web browser.
the GUI version won't pull information from rocksmith for me. it says game is running but doesn't display information.
