History

Group
Bros -- Netherlands, founded May 1988

The second ranked intro from Bros, a Dutch cracking group founded in May 1988. No CSDb release match has been confirmed for this specific production, and no individual credits for code, music, or graphics have been identified. The CSDb search returned no matching results. Bros was based in the Netherlands, operating at the heart of the Dutch scene during its peak years. The group is best known for their extraordinary #63 Bros-01 -- a thirty-SID jukebox intro containing music from seventeen different composers including Red, Jeroen Tel, JCH, and Drax. A third Bros entry appears at #233 Bros-03. Comments on intros.c64.org from Motion (2015) and Conrad (2011) confirm the intro's continued visibility. The Netherlands' dense network of sceners and BBS operators gave even mid-tier Dutch groups access to extensive distribution infrastructure, and Bros' three ranked entries demonstrate consistent output quality across their catalogue.
