Monster Hunter Portable 3rd (HD Ver. or not)

[arbitor]

Hello!

I have a confusing problem and I tried to look around this forum and couldn't find any solution to it.

I have 2 PCs (in LAN).
Both PC 1 and 2 have no firewall blocking the PPSSPP.exe.
PC 2 is even portforwarded for the TCP port that adhoc server lists.
PC 2. is running the adhoc server, the ip is 192.168.1.120
Both PC 1 and PC 2 emulators have proAdhocServer = 192.168.1.120 in the ppsspp.ini and also have their corresponding macaddress from the PC.
They also have both different nicknames (PSP names).
Both PC's also have WlanAdhocChannel = 0
I start game with PC 1, no problems, go to online guildhall in MANUAL mode and select Guild Hall 24.
Adhoc server shows up it requests information and connects fine.
I start game with PC 2, no problems, go to online guildhall in MANUAL mode and select Guild Hall 24.
Adhoc server shows up it requests information and connects fine.

BUT, neither of the games show up in the same guildhall. It's like they are in different servers. What could be the problem?
