RoWheel Bridge

A .NET 9.0 application that bridges DirectInput steering wheel devices to virtual Xbox controllers with force feedback support.

Usage

• Run the program as admin for force feedback to work correctly
• A calibration settings .Json file is created after first-time calibration. It will be referenced for later startups if present
• Use --debug or -d flag to see detailed device detection information

Multi-Device Support

RoWheel Bridge supports both combined and separate device setups:

• Combined Setup: Use a single device (like a Logitech G29) for steering, pedals, and shifters
• Separate Setup: Use different devices for each component (e.g., separate wheelbase, pedal set, and shifter)
• Mixed Setup: Any combination of the above (e.g., combined wheel+pedals with separate shifter)

During device selection, you'll be prompted to choose:

1. Steering Wheel Device - The device with your steering wheel (usually has force feedback)
2. Pedal Device - Can be the same as steering wheel or a separate pedal set
3. Shifter Device - Optional separate shifter/button box, or use steering wheel device

Device Detection

The program detects and categorizes devices automatically:

• Wheelbase: Devices with force feedback and multiple axes (steering wheels)
• Pedals: Devices with multiple axes but fewer buttons (dedicated pedal sets)
• Shifter/Buttons: Devices with many buttons but fewer axes (button boxes, shifters)
• Multi-axis: General devices that don't fit other categories

Use the --debug flag to see detailed device information and categorization.

Calibration Options

During calibration, you can skip optional components:

• Clutch Pedal: Many setups only have throttle and brake pedals
• Shift Buttons: Skip if you don't have paddle shifters or shift buttons

The program works perfectly with just steering wheel, throttle, and brake pedals calibrated.

Requirements

• Windows 10/11
• DirectInput compatible steering wheel/pedals
• ViGEm Bus Driver (https://github.com/nefarius/ViGEmBus/releases)

Default Input Mapping

Custom input mapping is planned to be added soon.

| Steering Wheel Input | Xbox Controller Output | Required | |---------------------|------------------------|----------| | Steering Wheel | Left Thumbstick X | Yes | | Throttle Pedal | Right Trigger | Yes | | Brake Pedal | Left Trigger | Yes | | Clutch Pedal | Left Thumbstick Y | No | | Shift Up Button | Y Button | No | | Shift Down Button | X Button | No |

Force Feedback Implementation

For force feedback to work in your game, send vibration calls through HapticService

• Xbox controller vibration from Roblox is converted to steering wheel force feedback
• Small Motor = Negative torque (left force)
• Large Motor = Positive torque (right force)
