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

[SuperLarno]

Hi Everybody (first post so sorry if I've done anything incorrect)
I've been trying to get multiplayer working for the past week or so but with no luck.

I've went to every tutorial i could find on how to get online on MHP3rd and Freedom Unite but with no luck so far, me and my friend can see each other in the Guild Hall but when we try to begin a quest, it goes to an infinite loading screen or when we do load, the other breaks off as soon as it loads.

We've tried everything like :
Using Tunngle, Hamatchi and Evolve (not at the same time)
Using UPnP on Tunngle
Running adhoc Pro server in the background
Using PPSSPP Version 9.9.1
Using PPSSPP Version 1.1.1

Basically we've followed every tutorial I can find but to no avail and that's why I've came here for help
