Player 2 won't work on netplay

[berry095]

So I was trying to playing New Super Mario Bros. Wii with my friend, but when we got to the multiplayer screen for the second player to come in none of the buttons would work on the second player (we both use emulated wii remotes). We tried switching and first player would always be fine but player 2 would be unable to play. we tried switching hosts, different controllers etc. nothing worked so I've come here to see if you have any suggestions
