Installation

Requirements:

Automatic Installation

  1. Download the latest installer mxbmrp3-Setup.exe
  2. Run the installer - it will:
    • Auto-detect your MX Bikes and GP Bikes installations (Steam or standalone)
    • Let you choose which games to install for
    • Install to the correct plugins folder for each game
    • Handle upgrades automatically (preserves your settings)

Manual Installation

  1. Download the latest release archive mxbmrp3.zip
  2. Find your game’s plugins folder:
    • Steam: Right-click the game in your library → Manage → Browse local files → open plugins
    • Standalone: Navigate to your game installation folder (e.g., C:\Games\MX Bikes\ or C:\Games\GP Bikes\) → open plugins
  3. Extract the plugin files:
    • Copy mxbmrp3.dlo (MX Bikes) or mxbmrp3_gpb.dlo (GP Bikes) to the plugins/ folder
    • Copy the mxbmrp3_data/ folder to the plugins/ folder

    Do NOT delete the existing game files (proxy64.dlo, proxy_udp64.dlo, xinput64.dli, or telemetry64.dlo for GP Bikes) - these are native game files, not old plugin versions.

    Your directory should look like this after installation (files vary slightly by game):

    [Game]/
│   mxbikes.exe / gpbikes.exe
│   ...
│
└───plugins/
    ├── mxbmrp3_data/        ← Add this folder (from release)
    │   ├── fonts/           ← Font files (.fnt)
    │   ├── textures/        ← Texture files (.tga)
    │   └── icons/           ← Icon files (.tga)
    ├── mxbmrp3.dlo          ← Add this (MX Bikes only)
    ├── mxbmrp3_gpb.dlo      ← Add this (GP Bikes only)
    ├── proxy_udp64.dlo      ← Keep (native game file)
    ├── proxy64.dlo          ← Keep (native game file)
    ├── xinput64.dli         ← Keep (native game file)
    └── telemetry64.dlo      ← Keep (GP Bikes only)

After Installation

Launch the game - the plugin will load automatically. Some elements are enabled by default and can be repositioned or configured via the settings menu. If nothing appears, see Troubleshooting.

Controls

Mouse

Keyboard Shortcuts

Keyboard and controller hotkeys can be customized in Settings > Hotkeys. By default, only the settings menu hotkey is configured:

Configuration

Use the settings menu (Tilde key or [=] settings button) to configure all HUDs and widgets. Hover over any setting to see its description - all controls have in-game tooltips explaining their function.

The settings menu provides:

All settings are automatically saved between sessions.

Profiles

Four separate profiles store complete HUD layout configurations:

Auto-switch (disabled by default) automatically changes profiles based on session type.

HUDs & Widgets

All HUDs and widgets are configurable via the settings menu or directly in the .ini file.

Advanced Settings

All plugin settings are stored in mxbmrp3_settings.ini in your user data folder.

In-game vs INI-only settings:

INI structure:

Editing the INI file:

With the game closed (recommended):

  1. Exit the game completely
  2. Edit mxbmrp3_settings.ini
  3. Launch the game to apply changes

Hot reload (for rapid iteration):

  1. Disable Auto-Save in Settings > General
  2. Edit the INI file while the game is running
  3. Use the Reload Config hotkey to apply changes (bind it in Settings > Hotkeys)

If Auto-Save is enabled, changes made to the INI while the game is running will be overwritten.

Modding

Plugin data and custom assets are stored in Documents\PiBoSo\[Game]\mxbmrp3\.

Custom Assets

Add custom fonts, textures, and icons by placing files in the appropriate subfolder:

mxbmrp3/
├── fonts/       ← Custom .fnt files
├── textures/    ← Custom .tga textures
└── icons/       ← Custom .tga icons

On game startup, the plugin syncs these files to the plugin’s data directory (plugins/mxbmrp3_data/). User files with the same name as bundled assets will override them. This keeps your customizations separate from the plugin installation, so updates won’t overwrite your files. Restart the game after adding or modifying assets.

Textures use the naming convention {element_name}_{number}.tga (e.g., standings_hud_1.tga). They’re auto-discovered and selectable via the Texture control in each HUD’s settings. Source design files (PSD) are available in assets/.

Fonts (.fnt files) are auto-discovered and assignable to categories (Title, Normal, Strong, Marker, Small) in Settings > Appearance. To generate fonts, use the fontgen utility provided by PiBoSo. See this forum post for details. An example configuration is provided in fontgen.cfg.

Icons (.tga files) are discovered alphabetically and available for tracked rider customization.

Data Files

File Description
mxbmrp3_settings.ini All HUD settings (positions, visibility, options)
mxbmrp3_personal_bests.json Personal best lap times per track/bike/category
mxbmrp3_tracked_riders.json Tracked riders with colors and icons
rumble_profiles.json Per-bike rumble effect profiles
odometer.json Per-bike odometer and trip meter data
