if I don't find a solution to this problem, then it's still possible to create a modern spa application that will be deployed on some server with Windows, where various folders of mugen games will lie next to it. Then you can go from the spa application (where you can select some game) to these static pages with games, and on the html pages themselves, just add my custom script, which will take the ID from the browser storage to connect to the room with the game from the server (rooms with games must be created on server), so that you can was to implement a webrts connection for 2 users.
