Hello Dolphin devs! I've had this idea/topic in my head for a while now. I would just like to suggest (if not already an added feature) the abilty to netplay gamecube games that implemented GameBoy Advance's as controllers ie Legend of Zelda: Four Swords Adevntures. I've tried this before and it appears (to us) that there may be issues with using a gameboy controller for netplay (probably due to it not being supported really). I'm just wondering if the compatability with gba emulators for using gameboy's as controllers on netplay would be a possible feature in future dolphin versions, being considered at all, or maybe even in development. 
Even if it's demanding it would still be awesome to have Four Swords be playable online if you have a good computer.
