Dumping GameCube BIOS to use in Dolphin?

[SassmasterMaxie]

I tried searching the forums but couldn't find anything relating to this, so... how would I go about dumping my GC BIOS so that I can use it in Dolphin, and then where would I put the dumped files so that Dolphin can read them?

I'd just been using Dolphin to play my dumped games and that's all fine and dandy but it would be nice to be able to access the BIOS as well.
