This is an unofficial open-source mod for Forza Horizon 6, the racing game, that adds a custom in-game radio station. Instead of being limited to the radio stations the game ships with, you can feed it music from a folder on your computer, from YouTube or YouTube Music URLs, or from a Jellyfin media server you run yourself. The audio plays through the game's own radio system, so it fades during menus and responds to volume settings the same way the built-in stations do. Installation involves downloading a ZIP from Nexus Mods, extracting it into the game folder, and adjusting two audio settings in-game. A small web dashboard runs at a local address in your browser and gives you transport controls, volume, an equalizer, and the ability to switch music sources. The mod also supports a quick skip gesture: turning the in-game radio dial away and back within one second skips to the next track. For YouTube playback, three external tools need to be installed: yt-dlp (a video downloader), ffmpeg (a media converter), and Deno (a JavaScript runtime). The README includes the exact command-line instructions to install them. Some formats beyond MP3, FLAC, WAV, and OGG also need ffmpeg to play from local files. Private or age-restricted YouTube content additionally requires a cookies file exported from your browser. The project is written in C++ and produces a Windows DLL file that the game loads on startup. It can be compiled on Windows with Visual Studio or cross-compiled on Linux using a specific toolchain called llvm-mingw. Build scripts handle fetching dependencies, compiling, and copying files into the game directory. The author wrote this because an existing Spotify-based radio mod for the same game was closed-source and required a paid subscription. This one is licensed under GPLv3, meaning anyone can modify or redistribute it as long as they keep the same license. The README includes a troubleshooting table covering common problems and their fixes.
