Steam Integration for Non-Steam Games Launched Through LaunchBox

📋 Summary

Add native support to LaunchBox for maintaining Steam integration (overlay, controller config, and “Now Playing” status) when launching non-Steam games through LaunchBox after it has been added as a non-Steam shortcut in the Steam client.

🎯 Feature Overview

This feature would replicate the functionality of the now-unmaintained SteamLauncher plugin by:

• Ensuring all games launched from LaunchBox/Big Box (when LaunchBox is run via Steam) retain Steam overlay and controller support.

• Displaying the current game being played in the user’s Steam status.

• Avoiding the need to clutter Steam with hundreds of manual emulator/ROM shortcuts.

• Optionally providing settings to customize platform labels and control per-platform or per-game Steam integration behavior.

📦 Benefits

• Seamless Steam overlay support for any LaunchBox game, including emulated titles.

• Full use of Steam controller profiles and per-game bindings.

• Improved experience for users who launch LaunchBox via Steam and want continuity of Steam features.

• Removes the need for third-party plugins or manual configuration.
