Inconsistent Online mode

[LaVol-P]

If I look online, people say that wifi Netplay isn't available through the MelonDs core of retroarch. Maybe it was updated and no-one talks about it, but I managed to get it working and did a few games on Metroid Prime Hunters. The problem is that when I enter online mode through that game, it says that the online ID from the game and the "console" don't match. Which causes to reset online data, and changes my friend code. And if I ever back out from the online mode after that, I can no longer enter it again, it fails to connect to the servers I get an error "52000"

Any clue ???
