- Fantastic 4 Cracking Group — Italy, founded 1983
The thirteenth numbered crack intro from Fantastic 4 Cracking Group, ranking 528th overall. No CSDb match was confirmed and no individual credits have been identified for code, music, or graphics. A comment on intros.c64.org from Ze Smasher — himself an F4CG member — dates from 2004, indicating the intro was catalogued early in the preservation community's efforts. F4CG was founded in Italy in 1983, the same year as the C64's European commercial launch. The group's numbered intro series stretched past ninety entries, making them one of the most prolific intro producers in C64 history. This thirteenth entry falls in the lower portion of the series, likely from the late 1980s. F4CG's longevity — spanning from 1983 well into the 1990s — is remarkable and largely unmatched by contemporaries. Other F4CG intros in this collection include #14 F4CG-32, #163 F4CG-09, #30 F4CG-08, and #105 F4CG-01.
