I just opened Sonic Colors and I cannot see anywhere how to add a second player. When I start the Wii, my 1 and 2 player lights on my remotes are lit like usual. But once Sonic Colors starts, it kills the second player remote. It isn't batteries or any kind of syncing issue. I've switched remotes and it does the same thing. I also put in another game and both remotes worked like usual. The manual says there is a two-player mode. I'm sure I'm missing something obvious. Any help is appreciated.
