Yep, fairly certain you are right about the situation with FM sound on Master Systems - you need a Japanese set up with either the FM Module or a Japanese Master System.
The only other thing to note, is that US/PAL games sometimes left the FM audio in place, if the Japanese version of the game supported it.
