Yesterday I downloaded my first Virtual Console game thanks to Club Nintendo.  I know Kirby Dream Land is single player, I'd like to know this for other games that may use them.  I remember Game Boy games were able to use link cable features for two player gaming.  Also I remember the infared feature (labeled Comm on the GBC) that some games, like Pokemon Gold used.

I was wondering, is it possible to link Game Boy or GBC games together with the 3DS?  I don't know if this applies, but is the infared on the 3DS for games that used the infared on the GBC?  I keep looking at that infared thing, but can't figure out what it's for.  Seeing the virtual console, I can only thing that feature on GBC

Please answer and thanks!
