Breath of Fire 2 SPC hacking

Okay, so I've asked this question on numerous boards (such as Rom Hacking) and they tossed it aside like an old bag of moldy tangerines, so, I'll ask here. This is a game that has two battle themes, and switches from one to another halfway in the game (after you get the flute in order to save the fat queen in Tune Land). Yes, there are discussions where people say the second battle theme is better; well I don't. I think it's garbage compared to the other one, but what I want to know is, what address(es) tell the game to switch the SPC data halfway? What values need to be changed to force the BOF2 to use the Cross Counter battle theme throughout the entire game? Surely, someone out there has information for the SPC banks or similar info with Breath of Fire 2. I really would like to know just how complicated it would be to make such a change. If this is a double post, I apologize.
