DARKSOFT Darius Gaiden EXTRA: Missing Background Layer on Zone D

[Darksoft]

@TMF68k @KRG Please confirm or add whatever necessary. Thanks.

The absence of a song in zone C of the marathon mode is a specification.
In Normal Mode, the songs from Zone A to Zone B and from Zone A to Zone C are played in a connected manner.
Therefore, there is no song in zone C.
