The 3rd disc contains 2 Arranged Medley tracks, and is located within the main packaging, rather than being a separate case.
The Dead Zone arrange sounds like it was taken directly from a vinyl or tape source, so it's possible that it's a reprint of this 1986 cassette (partially or entirely)

Track names will have to be entered from the booklet scans, as retail websites only list the games and not the full 99-track breakdown that is printed in the booklet.
