Dynamix Crack Intro #03 is a November 1989 release from the German cracking group Dynamix, preserved on CSDb as entry #96847. The intro was coded by Vokke, with charset by Roger Rabbit and music by Chris (Chris Ammermuller) and JCH (Jens-Christian Huus). Two SID tracks are associated with this release: "Fantasia Country" by Chris and "Shadow Sun" by JCH -- both preserved in the High Voltage SID Collection. Doc Snyder credits JCH as the featured musician, with "Shadow Sun" as the primary track displayed on the page. The scrolltext -- attributed to The Syndicate of Dynamix -- announces a crack with the line "quality from Germany" and provides a Frankfurt postal address for contacts. This is the third of three Dynamix intros catalogued on Doc Snyder's page, each featuring a different coder: The Syndicate for #01, Roy for #02, and Vokke for #03. The release dates from just five months after the group's June 1989 founding.
