History

Released
February 1988
Code
The Parade International
Charset
uncredited
Group
Ikari — United Kingdom

Catalogued on CSDb as release #59152 under the name "Ikari Intro," this crack intro dates from February 1988. The Parade International handled the code, while the charset artist remains uncredited by name on CSDb. Doc Snyder's page — which links this as Ikari Crack Intro #08 — also credits The Parade International for both code and charset, along with music by Marc Buttery. The CSDb entry, however, lists the releasing group as The Sharks rather than Ikari, and records no music credit. No SID tune is documented in the CSDb release data. Ikari was a UK-based cracking group active throughout the late 1980s, responsible for a prolific series of numbered intros. The production is a relatively minimal affair compared to Ikari's later, more elaborate intros that featured multiple SID composers. Doc Snyder's verified CSDb link confirms the match between this entry and the intros.c64.org archive.
