+### Online Battle
+
+**Only matchmaking (with your imaginary friends) is supported! Online Battle does not (yet?) work!**
+
+The first person to start the Online Battle (now called host) will create a "matching room" with a given `roomId`, after that max 3 other people can join the created room.
+Non used slots during the matchmaking will be filled with CPUs after the timer runs out.
+As soon as a new member will join the room the timer will jump back to 60 secs again.
+Sending those 4 messages to all other users is also working properly.
+In order to use the Online Battle every user needs the same ICF, same rom version and same data version!
+If a room is full a new room will be created if another user starts an Online Battle.
+After a failed Online Battle the room will be deleted. The host is used for the timer countdown, so if the connection failes to the host the timer will stop and could create a "frozen" state.
+
+#### Information/Problems:
+
+- Online Battle uses UDP hole punching and opens port 50201?
+- `reflectorUri` seems related to that?
+- Timer countdown should be handled globally and not by one user
+- Game can freeze or can crash if someone (especially the host) leaves the matchmaking
