Unused Music#

The game has a huge amount of unused music. Famously the game used a pioneering dynamic music system that switches between different variations of a theme on the fly depending on what is happening in the game, and it turns out there is a large amount of unused bars of each song still present in the game files, with only around 60-70% of each song on disk actually used in the game.

Track

Description/Notes

Play File

3

Alternative end of level introduction fanfare with descending rather than ascending notes

7

Alternate/early shop theme

8

Version of the end of level tune with the melody of the intro/title screen music played by a crude chip instrument in parts. At the 45 second mark changes into a new part not used in the final song. This particular version of the tune is repeated throughout the file

10

Abrupt jingle

11

Another very different version of the end of level tune, also used at the end of track 8

12

Celebratory jingle. Perhaps originally intended for the completion of a level?

The last few tracks of this file also include the end sequence music, but the instruments used for the speech are missing in the intended instrument pack so this part is corrupted. They are present and complete in the end game songs files below.
