About Ouendan1/2 and EBA

I know this isnt really a help kind of question, but im wondering, does EBA and Ouendan use friend codes to play online? because i want to find some friends to challenge.

I don't recall them having wifi play to begin with.

oh? Well i thought my friend told me it was WIFI play ): oh well T.TEdit : Thanks btw

He was probably referring to local multiplayer, then.
