I think you misundestood me. There shouldn't be a server which is hosting games. The users can still host games and play among each other. As you give a friend a traversal hostcode, there could be a server which knows all hostcodes and the status of that hostcode. This list can then a user use, to find open games in dolphin.The game would still take place between the players not over a server. The host would only tell the server, if the game was started or not. Game Ranger does the same thing. It doesn't handle the game playing between players. It only shows, which games are hosted and which are currently playing. The game itself take place between the players.

Like I said, there's no server infra - there's no central server.

How is Dolphin supposed to list all hosted games across the internet when they're peer to peer?

if we had a centralized server, even for organizing games, then there'd definitely be a possibility for that

Unfortunately our netplay has stagnated and there hasn't been much change recently to the actual core of it.

ok, maybe i misunderstood the traversal server thing. I thought the traversal server does know all hostcodes already. Isn't that so?

I saw the host code or room id is each time different. Sure that nothing does know about that?

Users don't have to use the traversal server though, and it doesn't work with all routers.

And, I'm not entirely aware if it knows more than the code, or if users would want anyone to be able to join their games.
