Hello, I made an account to post this question
never posted before, so please tell me if i am doing something wrong (wrong thread etc)
I am trying to play with a group of friends using tunngle, simple enough, did this before with another friend and it works. So i tried it with them, we can see each other in tunggle, i did the usual setting for LAN in ppsspp, gave them my ip, dns, did the settings. I started the Adhocserver and told them to join the room, but i can't see them. I looked at the adhocserver and sure enough I can see them in the log, i can see their names and that they are requesting info,etc, but no dice in game.
tried googling and other things, no solution as far as i can see.
So can anyone tell me what I did wrong or point me torwards someone who had this problem and was solved?
