Two versions of the MS-DOS CD-ROM release were developed; one features full-motion video during gameplay, requiring a RealMagic hardware MPEG decoder; the other, more common version is only capable of playing video during non-interactive cutscenes, and substitutes sequences of static images taken from the video footage during interactive gameplay, however it also features a full orchestral Redbook audio soundtrack at these times, which the RealMagic version cannot use because it constantly streams video from the CD-ROM. Both versions use MIDI music whenever CD audio is unavailable.
