RetroArch: Player 2 has no input on Netplay

[Periko]

While on a Netplay session, Player 2 can't interact in any way, his controller/keyboard input is ignored. We tried different ROMs and cores (mainly CPS-2, Neo Geo and SNES), but it's not working.

Any ideas? Thanks in advance.

I don't think net play intended for more then 1 player?
