GameCube -> Game Boy Advance Adapter

[Hucz]

It seems no other homebrew application I've come across that runs on the GameCube or Wii has support for the Game Boy Advance to GameCube controller adapter, which seems essential to me if I wanted to play Game Boy games on my TV via a solid emulator. I'm sure there are huge technological challenges that explain why no one has been able to do it, but I feel if anyone was capable of it, it would be the creator of this fantastic emulator. What are your thoughts on this? Cheers.
