Can a GC game be played with a classic controller?

[Gamerace]

I suspect the answer is no.

In particular I'm looking to play Fire Emblem: PoR which is very hard to find but my local store finally got a used copy.

I have a GC controller but that requires playing on the floor instead of the couch, something I will not consider especially given the long playtimes involved in a FE game.     Wireless GC controllers and an extension cord are also impossible to find. Checked already.

I fell in love with FE from the Wii's FE:RD and would love to add this to my collection but needing to use the GC controller would be a deal breaker.

Please say yes.
