To comply with modern web security sandboxing and digital copyright distribution models, Grand Theft Radio operates entirely on your local machine. Your files are never sent to a server.
To load the station wheels, you must provide a local directory folder containing the original high-fidelity audio loops and front-end image assets extracted from your personal game installation files.
🛒 Tools Needed
- A licensed PC installation of The Definitive Edition trilogy games via Steam, Rockstar Launcher, or Epic Games.
- A copy of FModel (a free, lightweight open-source data viewer for Unreal Engine archive files). Download it from fmodel.app.
📦 Step 1: Exporting Game Assets with FModel
-
Launch FModel and set your primary project execution mode profile to
Unreal Engine.
UE Version: GAME_GTATheTrilogyDefinitiveEdition
-
Go to the top menu option
Directory ➞ Change Selection and navigate straight to your game installation's data archive package directory:
.../Grand Theft Auto [Game Name] Definitive Edition/Gameface/Content/Paks/
-
To Extract Radio Station Icons: In FModel's left navigation asset tree, look up the following path block:
Gameface ➞ Content ➞ Textures ➞ FrontEnd ➞ Radio.
Right-click the parent Radio folder and select Export Folder Images.
-
To Extract Audio Track Streams: Go back up the left asset navigation panel tree, and expand:
Gameface ➞ Content ➞ Audio ➞ Radio.
Right-click this parent Radio audio folder and select Export Folder Packages.
📁 Step 2: Arranging Your Local Folder Grid
Create a fresh, clean folder anywhere on your computer (e.g., named GTAIII or GTAVC) and arrange your newly extracted standard asset conversions exactly matching this layout mapping structural model:
📁 GTAIII / (Your Mounted Directory)
├── 📄 radio_config.json <-- Provided Server Layout Blueprint File
├── 💼 T_radio_none_BC.png <-- "Radio Off" Slate Circle Graphic Logo
├── 📁 Chatterbox / <-- Station Subfolder Key Identity Name
│ ├── 💼 T_fe_radio9_BC.png <-- Individual Channel Logo Texture Asset
│ ├── 🎵 CHAT_1.ogg <-- Audio Chapter Loop Segment 1 File
│ ╚── 🎵 CHAT_2.ogg
├── 📁 Head /
│ ├── 💼 T_fe_radio1_BC.png
│ ╚── 🎵 HEAD_1.ogg
╚── 📁 mp3 / <-- Optional Custom Station Folder
├── 🎵 Song_File_01.mp3 <-- Drop your own custom audio tracks here
╚── 🎵 Song_File_02.mp3 to automatically activate "mp3 player"!
📻 Step 3: Initializing The Player
- Open your desired radio game page link from the main hub screen.
- Click the
Select Assets Folder button, target the parent directory folder you just built, and grant the browser folder-read clearance.
- Spin the radio channel selection dial wheel and enjoy the drive!
