The big limitation on spc hacking is the difficulty of standardizing music code between games. That's why it's next to impossible to create a master spc sequencer that could import, export, edit, and create musical instructions within and between ROMs, regardless of the specific games at issue. However, a manual approximation of this is still possible, which we see in your work here, and also in the Temporal Flux example of certain FF VI tracks being transplanted into the CT ROM. I dream of further progress in this direction. That encompasses the extent of my "thoughts" on the subject. And, as you can infer from my lay description, I'm not the person to contribute to this. Are you?
