Forza Data Web (Work in progress)

Forza Motorsport 7 / Horizon 4 Data-Out feature receiver web application, and some debug tools.

Based on Turn10 official specifications here.

Objectives

The idea behind this Web Application is to provide access to Forza Motorsport 7 or Forza Horizon 4 telemetry of a game session to Web users.

Game data reading is made by a Web backend, parsed and routed via WebSocket to an rich UI Web Interface to provide real-time data on a game session.

Several game sessions can be read at same time by the backend, and, of course, several web users can read the same game session data.

Progress

For the moment, game data can be observed using a simple console.

Samples can be recorded using the sample recorder program, and will be playable later.

No Web interface for the moment.

Protocol compatibility

Game	Sled	Car Dash	Horizon
Forza Motorsport 7	Yes	Yes	N/A
Forza Horizon 4	Yes	No	No

Note : Forza Horizon 4 is actually using an undocumented protocol. Only the Sled part of it can be read.

How to test

Prerequisites

1. Git
2. Git LFS
3. .NET Core SDK

Get sources

Clone (using Git) this repository to your Windows, Mac or Linux computer. You will need to install Git LFS before cloning the repository to get large sample files.

Enable Data-Out feature in game

Start Forza Motorsport 7 or Forza Horizon 4 on your Windows 10 computer or your Xbox. Go to game options, then HUD options. At the bottom of the screen :

1. Data Out IP Address : enter the IP Address of the computer that will run the console program
2. Data Out IP Port : enter the network port you want to listen on this computer (1024 to 65535)
3. Data Out Packet Format : choose Sled or Car Dash, but you will get more data using Car Dash format. Forza Horizon 4 does not have this option.
4. Data Out : set to ON

Run console program

If you're playing on a Windows computer, you have to use another computer to run the console program, or you will receive nothing.

Launch your command line to Console source directory. Then run this command:

dotnet run -ServerIpAddress <serverIpAddress> -Port <port>

• -ServerIpAddress : the IP Address of your Xbox or Computer that runs the game.
• -Port : the network port you chose in-game

For example, if your Xbox or Windows Game Computer have 192.168.0.10 IP Address, and you chose 7777 network port to communicate:

dotnet run -ServerIpAddress 192.168.0.10 -Port 7777

Note : If you want to quit the console program, just hit CTRL+C or CTRL+Break.

Record samples

Launch your command line to SampleRecorder source directory. Then run this command:

dotnet run -ServerIpAddress <serverIpAddress> -Port <port> -Output <file>

Arguments

• -ServerIpAddress : the IP Address of your Xbox or Computer that runs the game.
• -Port : the network port you chose in-game
• -Output : the output file to record to

Example

dotnet run -ServerIpAddress 192.168.0.10 -Port 7777 -Output "Samples\Sample.bin"

Note : If you want to quit the recorder program, just hit CTRL+C or CTRL+Break. The output file will be deleted if no data is received.
