Catalogued on CSDb as release #251142 — "Nostalgia Intro 81" — this crack intro was released on 16 March 2025 and carries a CSDb rating of 9.33/10. Goblin contributed the charset, Jedi created the graphics, and 6R6 — Glenn Rune Gallefoss — composed the SID tune "Alien Legion," preserved in the HVSC. The coder is uncredited by name on CSDb. The 2025 release date underscores Nostalgia's extraordinary longevity — the group was founded in February 1995 and has now been active for three decades. Doc Snyder's page documents the group's extensive catalogue, with Jedi and 6R6 appearing as regular contributors across the group's intro series. Nostalgia has produced over 80 numbered intros, making them one of the most prolific crack intro producers in C64 history. The group maintained a website at n0stalgia.org and continued to crack and re-release classic software well into the modern era.
