Ripping Non-Sappy music from GBA Roms

[maximumxp]

Hi! New poster here.
I was trying to not avail to rip music from Duel Masters - Shadow Of the Code from the GBA ROM. Tried GbaMusRiper and "No sound engine was found" error came up. So I guess it's not in sappy sound engine. Question is: ¿Is there something I can do to rip the files from other tipes of sound engines? (Recording from the game is not an option, just wanted to clarify).
I would love to have the sound files directly from the game, as every OST on youtube sounds like in a can.
Thanks for you help in advance

I don't know why, but i have the same problem too on GBA games like Super Puzzle Fighter II Turbo and Rhythm Tengoku. 

So far, there are no answers yet.

There is not an easy method to do so, as I believe you have to track instructions which point to each instrument to build a sequence. I think loveemu (?) has done things like this before, but not anything I'm positive about.
