he also said that everything is the same just different OS.

Also not all games need the ports to be opened for every player.
Games that also got infrastructure mode as well dont need for the most part.
Thats what I discovered anyway with star wars.

It can, even localhost can be blocked by network security software.
I always need to put my PPSSPP exe as exclusion on my Anti-virus (Eset Internet Security) whenever i want to test on localhost, otherwise it can't see each other instance.

Which is why they need to test it using built-in Adhoc server just to make sure.
