Would it be hard to rip it? As in NSF ripping.
If I'm not mistaken, all the games share the same code, including music code, which is probably ripped from Dr. Mario for all the games, because the Fever is still there. They rearranged their music to fit the Dr. Mario sound engine's limits. After all, they ripped many sound engines in their life, including the Konami one.
Edit: Yeah, the music is definitely rearranged because the noise channel has similar percussion.
