Monster Hunter Guild Hall Troubleshooting/checklist

[Exoeros]

So I have been reading over everything and i'm sorry but i'm just a tad confused about a few things.
So basically I have all the settings down, but for the steps you open tunngle and both join the same room.
After wards you the host in this case me, I open adhocserver and leave it open right? or do we both?
We have the same game and emulator(check).
Now in the ppsspp.ini under the proadhocserver = ( I put my tunngle V ip here?) and when you say all players should have the same proadhocserver in their ppsspp.ini, do you mean they should all be using the hosts tunggle V ip?

Also on a side note do I specifically need the ppsspp.ini from http://forums.ppsspp.org/showthread.php?tid=8653

The user chelc was saying that he was having no problems with everyone used that specific ppsspp.ini
