Kingdom Hearts: Birth By Sleep Final Mix

[RitsuoFox]

For a long time, i tried to play KH:BBS FM with my brother and my friend., the PPSSPP is the only emulator that (as far as i know) can play adhoc matches from the PC to PSP (He have a PSP, but i don't) and online. The only problem is, whenever i try to connect to the Online Mirage Arena, the game just says "Connection lost" and if i try to go in again, it freezes. Does anyone know when the ad-hoc of this game will work? Or, if there's any fixes to that problem, can anyone tell me how to fix it? I really want to play it with my brother, or with my friend online. (Sorry if my english is bad, i'm Brazilian.)
