I am running 3.52 m33 firmware and want to play multiplayer with my mate who is running 2.82 firmware. mine is a Chinese edition and his is Australian, but when we try to connect on multiplayer, it serches but does not connect. I have not found the exact same problem, everyone else seems able to start the game, yet i can't register the other console.(when it says searching for other players nothing comes up) I have been to ALOT of other threads looking for an answer. I am running an iso of the game and his is on UMD. where am i going wrong? (there seems to be so many differences in our stuff this might be hard to determine.) I have the switch on the side on the correct position. If anyone knows what i'm doing wrong (it could be anything, im a bit of a newbie) please tell me, no matter how obvious it could be. Ta in advance.
