J.D. Sachs (James D. Sachs) — "Time Crystal" preview (ripped)
Group
The Wanderer Group — Germany, founded 1987

Coded by Speedcracker and released in October 1987, this intro from The Wanderer Group features music ripped from J.D. Sachs' "Time Crystal" preview — a game tune preserved in the HVSC. Speedcracker was a core member whose handle appeared in the intros.c64.org comments, confirming his continued connection to the group decades later. The Wanderer Group was founded in Germany in 1987 and operated with the abbreviation TWG. Another TWG intro appears in the rankings at #56 TWG-02, coded by Lui with music by Fred Gray — demonstrating that the group had multiple coders contributing to their intro catalogue. The CSDb entry lists this as the "Wanderer Intro" without further description. TWG maintained a website at wanderer-group.de, indicating the group's interest in preserving their legacy. The choice of the "Time Crystal" preview tune — an unreleased game's music — shows how crackers accessed pre-release material through their distribution networks.
