OOC Radio for FH6

An in-game-only Forza Horizon 6 radio mod that streams Out of Character Radio straight onto the radio dial.

OOC Radio for FH6 adds a single new radio station to Forza Horizon 6, fed by the OOC Radio stream. It plugs into the game the same way every other station does: it ducks for menus, follows your in-game volume slider, and fades on loading screens. Track title/artist/album art come from OOC Radio's own metadata API rather than plain stream tags, and when a presenter is live on air, the dial's artist line and artwork switch to show who it is.

There is no web dashboard and no other audio sources bolted on — this is a single-purpose mod. Everything is configured by hand-editing one config.toml.

• Streams the OOC Radio direct feed straight into FH6's radio bus.
• Real now-playing metadata (title / artist / album / art) from OOC Radio's authenticated API, not just raw stream tags.
• Live presenter detection — the dial shows who's on air, in real time.
• Race-start action, loudness normalization, and a 5-band equalizer.
• No dashboard, no background web server, no other sources — nothing running beyond what's needed to play one station.

1. Get an API key. Open https://oocradio.com/, go to Developer, and create a key (looks like oocr_live_...).
2. Download the latest release from the Releases page.
3. Close Forza Horizon 6 if it's running, then extract the ZIP directly into the folder that contains forzahorizon6.exe. Typical locations:

   Steam    ...\steamapps\common\ForzaHorizon6
   Xbox app ...\XboxGames\Forza Horizon 6\Content
   

4. Set your API key. Open fh6-radio\config.toml (now sitting next to version.dll) in any text editor and paste your key in:

   [ooc_radio]
   enabled = true
   api_key = 'oocr_live_YOUR_KEY_HERE'

5. Launch the game. Go to Settings → Audio and set:
   • Radio DJ → Off (otherwise the in-game DJ talks over tracks)
   • Streamer Mode → On (the new station only appears with this on — it's how FH6 exposes a station slot that's safe for a mod to control)
6. Cycle radio stations in-game until you land on the new one. Audio only plays while that station is selected.

If Windows Defender or another antivirus flags version.dll, that's a false positive from how the mod hooks into the game process — add an exclusion for the game folder.

Delete version.dll and the fh6-radio\ folder from the game directory. Nothing else was touched, so no repair/verify step is required (though running one won't hurt).

Requires Visual Studio 2022+ with the Desktop development with C++ workload (Windows), or CMake + llvm-mingw for a Linux cross-build.

This is a stripped-down, single-purpose fork of g0ldyy/fh6-universal-radio — all credit for the underlying game-hooking work (the version.dll proxy, FMOD audio hook, and in-game texture injection) belongs there. This fork removes every other audio source and the web dashboard, and replaces them with one hardcoded OOC Radio integration. See NOTICE for the full attribution chain.
