Trouble with LAN Ad-Hoc Multiplayer

[BigBroly]

Hello all,

I registered here because I have researched for a couple days now and I couldn't find an exact solution to my issue. I was wondering if someone could tell me what I'm doing wrong. My brother and I are trying to play LAN ad-hoc multiplayer on games like Tekken 5, BlazBlue, and MHFU. I have followed many tutorials, but cannot seem to figure out what I'm doing wrong. I am able to set up the server and connect to it and so is my brother, however, the problem is neither one of us can see each other in the lobby of any game. I have allowed the adhoc and ppsspp .exe files through Windows firewall private and public. I have set up both ppsspp.ini files correctly (both users have different MAC addresses and same host IP). I have even tried setting the host IP in DMZ mode on the router, but the results are the same. I have even tried setting up the server on a Virtualbox VM (with no antivirus installed) to make sure my antivirus of my main OS wasn't affecting anything. The results were the same - I can't see anyone join the lobby. The screens just look identical displaying empty lobbies on both PPSSPP's. Any suggestions as to what I'm doing wrong?

EDIT: I should mention I found a post with someone who had the same issues as this and he fixed it because both users had "different localizations" whatever that means. Can someone explain what he meant by that?
