- ABC Crackings — Netherlands, founded 1984
A 1985 intro from ABC Crackings, a Dutch group founded in 1984 and known by the abbreviation "ABC." No individual credits for code, music, or graphics are recorded on CSDb for this particular entry, leaving the authorship details unknown. The sparse documentation is characteristic of very early C64 crack intros, when individual credits were rarely preserved and productions circulated anonymously on floppy disks. ABC Crackings operated during the formative years of the Dutch cracking scene, which would later produce powerhouses like Hotline and Success. Their 1984 founding makes them one of the earliest Dutch groups on record. This is the third ABC Crackings entry in the rankings, alongside #229 ABC-01 and #283 ABC-02. The group left minimal traces in the broader archival record — no entries appear on Doc Snyder's page, Demozoo, or other scene databases beyond CSDb and intros.c64.org.
