Ad-Hoc I need help for MGS Portable Ops +

[Momo97]

Hi everyone, as you can see, I need help for Metal Gear Solid Portable Ops +, so, my problem is the next.
I'm using the v.1.2.1-12.
When i try to connect two PPSSPPs (on the same PC), i can´t do it, i am using AdhocServer.exe but it doesn't work.
First, i launch AdhocServer.exe for player one, next, i open ppsspp 1 and ppsspp 2, for both i have activated "enable networking WLAN" and i have the same ad hoc server ip address (127.0.0.1). This configuration works for other games, like Mortal Kombat, Dragon Ball Z Ttt, etc.
When the player that is going to join (player 2) try to do that, inside of the game (Adhoc or Adhoc +) appears an error (P7011SO).
I don't know what is happening ? because when try to connect in the option "free battle" on the main menu, it WORKS !!!
I am not sure but i think could be the version of the emulator.
If you can help me, I would appreciate.
