History

Released
February 1993
Group
Dytec (DTC) — Germany, founded 1990

Known on CSDb as "The Floodtro," this February 1993 crack intro was a joint coding effort between Little Big Man and Proton, both members of the Coolart subgroup. The soundtrack uses Jeroen Tel's "The Mon Demo 1991" — a composition from one of the C64's most celebrated musicians, best known for his work at Maniacs of Noise. Monk provided the graphics while Crossbow of Crest contributed the charset, making this a genuinely cross-group production. The intro was deployed across seven Dytec cracks including Circuit, JOSH, and Magic Fields. Dytec maintained a cooperation with Tristar & Red Sector Inc. during this period, further embedding them in the German scene network. This is one of several Dytec intros in this collection, alongside entries like Dytec #01 and Dytec #10.
