If I understand Mapper 30 right, it has a large amount of unused mapped space. According to NESDev, PRG RAM, PRG ROM, and mapper registers start at $4020 and continue to $FFFF.
Can we extend VRC6 audio into Mapper 30 by simply putting the VRC6 audio registers at $4044-$4053? (I'm working on a 128MB PRG RAM FPGA-based mapper that costs around $11 of circuitry and part of its register bank is VRC6 audio, hence the funny address.)
