Code
Jedi
Music
Michael Hendriks — "MCG Intromusic"
Group
Nostalgia — founded February 1995

This Nostalgia intro from 2004 was coded by Jedi, a prolific member who contributed both code and artwork across multiple group productions. The SID music was composed by Michael Hendriks, with the tune "MCG Intromusic" preserved in the HVSC under the FAME directory. Nostalgia was founded in February 1995 and adopted the tagline "Come to where the legend lives," building a reputation as dedicated preservationists who re-released classic C64 games with bug fixes and enhancements. The group's website at nostalgia.c64.org served as a hub for their releases. Doc Snyder's page documents multiple Nostalgia intros featuring work by members including 6R6 (Glenn Gallefoss), Jedi, Erhan, and S!R. This is one of many Nostalgia entries in the collection, with others including #206 no-08 and #256 no-02. Atlantis Prophecy's Recollection features interviews with scene members who reference Nostalgia's work, and Freeze64 issue 8 also covers the group.
