Ikari [IK] -- United Kingdom, founded July 1987

Ikari Crack Intro #04 is a C64 crack intro released on 22 December 1988 by the British cracking group Ikari. The intro was coded by Excell and features an exceptional multi-tune jukebox with SID compositions from six different musicians: Johannes Bjerregaard ("Chase"), Leffty ("Bangkok Fe"), JCH ("Nilfisk," "Shadow Sun," "Short 'n' Sad," "Revolutionary"), Diflex ("Rhenus Demo '88"), Jeroen Soede ("Funky Stuff"), and EVS ("Popcorn Mix"). CSDb lists nine SID tunes in total, all preserved in the HVSC. This multi-tune format -- offering users a selectable music menu -- was a hallmark of Ikari's premium intros. The sheer number of composers represented demonstrates the group's extensive network across the Dutch and Danish SID music scenes. Ikari was founded in July 1987 in the UK. The release is preserved on CSDb as release #53886, verified through the Doc Snyder link.
