SCC has two functions: sound processor and MegaROM mapper.
It's necessary as a mapper, but not necessary as a sound
processor (although it's recommended). I think it's weird
to treat it as one sole thing. In a real cartridge, of
course SCC is one IC, but these are two functions to be
emulated. I don't know if I can make myself clear about
this point...
And, please, don't forget SCC+. =)
