First, subscribe the gamebox and HTML Loader addon. Switch your branch to x86-64-Chromium+64-bit binaries. Then you can hold down the C key and click on the gamebox icon, then right-click on the game you want to play and select "Play on screen" in the drop-down menu. Next, you just need to go to the Entities tab in the extensions menu and select the "Game Screen" entity to generate a screen.
Also, you can check our official website[ofgamebox.netlify.app] for more details.

Only local games work, and only in a window, the Internet connection is excellent, the 86-bit version of Chrome, I downloaded everything, how can I fix it?
