as others have said, unless you can dump the protected microcontrollers as well as the ROMs then we can't properly emulate the versions with the crappy looped sound.
the microcontrollers drive the sound chips
almost nobody can dump the microcontrollers, they typically require decapping or otherwise deprotecting first, which is a very expensive specialized task.
