how to enable online multiplayer mode on tekken 6 : BR set up at ppsspp emulator

[Capeiro]

I play tekken 6: BR on ppsspp emulator installed on my windows. I can play offline (as expected), arcade mode and rest modes but I'm unable to use network mode. I've enabled the network option in settings and it starts up but no player is displayed, it's just searching on and on. I suppose I need to put extra efforts (a workaround probably) to make it occur.
I request to everybody having the appropriate knowledge for such a workaround leading to a solution for my issue.
