Code
Maniac
Music
Drax (Thomas Mogensen) — "Boneless"
Group
Ikari+Talent — United Kingdom, Talent founded 21 July 1989

Released in April 1991, this is the twenty-fifth numbered crack intro from the Ikari+Talent partnership, one of the most celebrated alliances in C64 cracking history. Maniac handled the code, while Drax — real name Thomas Mogensen — contributed the music "Boneless," preserved in the HVSC at /MUSICIANS/D/DRAX/Boneless.sid. Drax was among the most prolific and respected SID composers in the Danish scene, and his work appears across dozens of intros and demos. Ikari+Talent is massively represented in this collection, with entries ranging from #13 I+T-05 and #29 I+T-06 through #38 I+T-04, #51 I+T-01, and #62 I+T-10 — consistently appearing among the highest-ranked intros. The partnership combined Ikari's cracking prowess with Talent's intro-coding expertise, producing work that defined the standards of the genre.
