[Bug(?)] Phantasy Star Portable 2 and the Port Offset Conundrum

[Wishdream]

(10-19-2016 02:36 PM)AdamN Wrote:  Hmm.. there might be another network function i missed and being used by PSP2 that uses port but didn't shift the port number.

Does PSP2 also need Port Offset = 0 on Windows in order to work? or is it only happening on Linux (i don't have the game)

Btw, when using Port Offset = 0 does PSP2 binds port 80? just in case it uses non-adhoc network function that suppose to access HTTP port 80 by default, because as i remember only functions related to adhoc that was shifted by port offset.
I remember there was a game that bind port 80 and was conflicting with my webserver on my PC a game where we rides a dragon (don't remember the title and i haven't tested it with port offset back then)

I can't check if PSP2 binds to port 80 at the moment because of a typhoon, stuck on mobile.
But yes, Windows does need Port Offset = 0 to work as well. Beyond that, Windows will be also be stuck in the lobby and not get into the game.
This also applies to every other platform too including Android.

I placed the status of it in the first post to let everyone know.

So it does seem that PSP2 is using a network function that doesn't pass through the Port Offset.

EDIT: I did some port checking and these are the things that is used while connecting on Port Offset.

On Port Offset 3000

Using the Debug Log this is what I get from the Port 3000 one, I removed the un-readable bits:
