Are there any 2D fighters on PSP with infastructure?

I’ve noticed that lately fewer and fewer psp games are being given infastructure, the developers seem to be assuming that everyone owns a PS3 with ad hoc.

So this brings about the question, are there any 2D fighters on the PSP with infastructure? Nobody I know really has/uses a PSP anymore so I don’t want to invest time into a fighting game when i’ll have no real competition.

Oh and i’m aware of xlinkai, but i’d preferably like to play a fighting game with a decent sized community, something xlinkai lacks except for the really popular games (Monster Hunter).
