Tekken DR online or PSP vs PSP?

I was wondering if it has online or is it just PSP vs PSP? If it has online, how do you go online with it, I mean I have stup everything with connection setting and I can browse but but I dont see no one in the lobby.

You can download other players ghosts from online. But no, there is no true online.

You can fight against a friend locally though, with only one copy of the game.

it is only adhoc, no infrastructure battles

unless you can manage to get xlink kai to work
