Metal gear solid peace walker

[cherenando]

Hello i wanted to know if i could have a little help from you guys

this is my problem...

Im triying to play co-ops Missions in Metal Gear Solid: Peace walker with my brother but it doesn't seem to work

i get this everytime i try to "host" a mission

(check the attached Files to see the image)

the windows in the left is the "AdhocSever" the thing in the right side of the image is the Game "there has been a connection error" (or at least that what Google translate says )

I was following
Adhenovan's tutorial


I did everything it said (well that's what i think )

Do you know why this happened?

-I'm Using a NoteBook my brother is using one too
-I'm using a wirelessRouter
-the Wireless Option is enabled in the Emulator options
-I have hamachi but i'm not using it (just in case)

Also ... could somebody explain why MH3rd is easier to make work than Other games like MGS: pw? i have seen a lot of tutorials in the internet with people using the same game as example (Not saying i have the game)
