- Danish Crackers — Denmark, founded 1984
This intro from Danish Crackers — one of the earliest cracking groups not just in Denmark but in the entire European C64 scene — dates to the group's 1984–1985 active period. CSDb credits PMK for coding the group's intros, and the release page for their 1985 version (release 61846) shows the "Outlaw" SID was used as the musical accompaniment. Danish Crackers operated under the slogan "They make 'em, we break 'em" and are credited with pioneering several firsts: establishing Denmark's first cracking group and developing what is described as the world's first smooth-scrolling text effect. Co-founded by PMK and Jellyfish in 1984, the group dissolved by 1985 after releasing 112 titles. Intros.c64.org comments from multiple users recall this as their very first encounter with a crack intro, underscoring Danish Crackers' historical significance. The group's brief existence preceded the explosion of Danish scene activity that would later produce groups like Channel 42 and #25 The Dominators.
