Are you playing the pal version of the game ?

That's the original sound of the game. The NTSC emulator versions I've seen have a sound way too clean and arcade-y

In Japan, the SG-1000 Mark III had an optional FM Sound Unit that was later built into the rebranded Japanese version of the Master System, which is probably what you were hearing. Even some games not released in Japan had FM soundtracks (albeit very few), but just like with the Famicom and its mappers with sound generators, you can't use the FM Sound Unit with the western Master Systems. Sega does what Nintendoes :D
