How should/does Dolphin Handle GBA Connect Games?

[belomeclone]

I still have and love two GBA Connect games - Pac-Man VS. and Four Swords Adventures.

Both are excellent games. But both require at least one Game Boy connected to the Gamecube. I was wondering how something like this would be accomplished on the Dolphin. Both are just excellent party games.

Is there any way we could use the DS as a controller? Connected over Wifi? Or would it all need to be shown on the screen with the game? Do they sell USB to Gameboy cords (though I fully support the wireless movement.)

Thanks!
