tales of the world radiant mythology Trade ?

[Xillia]

first I wanna say that I truly love this emulator, it is the best one I have used, very fast and easy to use .

and I have some questions,

in this game tales of the world radiant mythology there is a "trade" option, but they say I have to turn the wlan on, how can I do that ?

also I can see that other players have special avatars and more armor and weapons , how can I get those ? Im level 20 and about 4 hours in the game.

and is there any dlc for this game ? and how can I get that ?

and the newest tales of the world radiant mythology, is it possible to play them in english ?

thank you
