There are same rather challenging problems with emulating the GC .. one of which is the PPC chip has custom opcodes.. just like the the N64 machined does. These opcodes are MMX style instructions for handling audio graphics and other things. I'm uncertain of the GPU details and it's not a keen interest too me to be honest .
The game cube will be about the same as the N64 in emulating it will take a lot of time and patience. As for bios and the chips in the gamecube, ehhhh grey area there. Physically removing the chip from the board to grab the bios is also a good way to wreck the IC and invalid it's data permanently. I might also point out Nintendo has been noted for encrypting there roms. It's like the bios included with the GC is either extremely simple or it's encrypted so you may be able to get it's contents but it's contents are useless anyhow.
I'll let someone else figure it out
