That sounds like an exciting project! To link a web address in LaunchBox that opens a browser for online play, you can create a new "PC" game entry for each Game & Watch title. In the game settings, you can set the "Launch" option to open a URL instead of a local file. Just input the web address for the Game & Watch simulation site.
You can also customize the game’s metadata with your scans, logos, and videos to enhance the experience. If you need more detailed steps, let me know!
