History

Released
September 1987
Group
Eagle Soft Incorporated — Canada, founded 1982

An Eagle Soft Incorporated crack intro used for the release of Mini Putt, dated 9 September 1987 in the scrolltext. Mitch Solomon coded the intro while the iconic eagle graphic — painted by Scorpio — dominates the display. Disassembly confirms the binary contains no SID register writes — the intro runs as a silent visual presentation. Doc Snyder's page preserves the full scrolltext, which takes competitive shots at rival group USSPE and sends greetings to NEPA, The Alliance, Triad, TTI, Fairlight, and supply group SOHO. The text references acquiring new Rush and Pink Floyd albums, reflecting the group's Canadian identity. ESI was founded in 1982 — one of the earliest cracking groups on the Commodore 64. This intro shares the same production team as the legendary #1 ESI-02 and the highly-ranked #7 ESI-09, all built around Scorpio's eagle artwork and Mitch's code.
