SPC Info For Importing Songs

I haven't found any SD3, and Lufia 2 uses a totally different SPC core. It seems are best bet in injecting songs, would be with other Squaresoft games.

To Quote JCE3000GT " FF6 is quite annoying to have to rewrite later Squaresoft game SPC codes. CT is rather plug and play really, as is RS3 to a small extent. You'd be surprised how relitively easy it is for Chrono Trigger. FF6 not so much, because it was the "first generation" "second edition" of the SPC code/core that Square used in their mainstream games from 1994-1996. Romancing SaGa 2 was the first to use this base SPC code/core before it was revised for FF6...then revised for each of the other games. RS2 is the ONLY OTHER game I've found that is 98% compatible with FF6. "

Sounds to me like injecting music straight into FF6 without composing the song from scratch might only be possible with RS2...
