SPC topic

I have a simple question for all of you SPC experts: Does FFVI and Secret of Evermore have the same SPC core or are they similar enough to do an import?

My idea is to replace "Kids Run Through The City" or "The day after" with "Cecil's town" from Secret of Evermore. I'll probably go for the second option since "Cecil's town" is a sad song and it would fit perfectly in the WOR.

If it is possible to do a direct import, does anyone know where to find the songs data in a Secret of Evermore ROM? I found the ROM map on Data Crystal but it doesn't specify which song is where...

Anyway if I don't find answers to my questions, I'll probably try to map the song in a midi sequencer and then write manually the song in the FFVI ROM but it would be a longer process I think...
