History

Released
1985
Group
Section 8 — Germany, founded 1983

The second crack intro from Section 8 — one of the earliest German cracking groups on the C64, active from 1983 to 1986. CSDb (group ID 25) identifies Section 8 under the extended name "Section 8 — The Softbusters" and classifies them as a cracker group and import group. This intro corresponds to the "Section 8 Scroll Intro" on CSDb (release 54580), coded by member JKL and dated to 1985. It was extensively reused across more than 60 cracked games, including titles such as Bounder, Captive, and BMX Stunts, often distributed through collaborations with groups like Vienna-Soft. JKL noted on intros.c64.org that he "was inspired by some Activision trailer" and wanted to write a "plain unfancy scroller." The group's core members — 4711, Draco, F-16, JKL, and The Boss — handled cracking, coding, and trading duties. Section 8 produced approximately 335 releases and was recognized in user comments as being among "the first cracking groups" to shape the early C64 scene.
