History

Released
August 1991
Group
Brainbombs [BOMZ] — Germany, founded 1990
Music
JCH (Jens-Christian Huus) — Strike Force; A-Man (Steven Diemer) — Thriller

This crack intro from the German group Brainbombs is catalogued on CSDb as release #54094, dated August 1991. CSDb notes this as a "fake rebuild" — a reconstruction rather than the original binary. No individual coder is credited on CSDb. Two SID tunes are featured — "Strike Force" by the Danish master JCH (Jens-Christian Huus) and "Thriller" by A-Man (Steven Diemer) — both preserved in the HVSC. Doc Snyder's page credits JCH for the music on this intro and notes its fake-rebuild status. The scrolltext credits Jack Alien for the accompanying crack and sends greetings to Hotline, Talent, Legend, Dominators, Bonzai, Faces, Crazy, Elite, and Success. Brainbombs was founded in 1990 in Germany under the irreverent tagline "Bla Bla Bla - here we are" and used the abbreviation BOMZ. The group also maintained contacts in the United States through BBS boards.
