I've been playing Phantasy Star 0 on wifi since it was first dumped, and I've never really had any problems, but for some reason, as of tonight, I'm getting every error code in the book! I've gotten 91010, 71010, and I get 86420 more than ANY of them. The official Nintendo site said that 86420 may mean it's because of my firewall, so I turned my firewall OFF, and I still got the code. :-\ What the heck's going on??? :'( Sorry if this is the wrong board, it just didn't seem like it'd fit into the Tech help board.
I just realized, it doesn't mess up on Free Play. It only messes up when I play with friends...? Come on, dude. :/
