- Yeti Factories — Germany, founded 1986
CSDb rates this 9.4/10 — identical to the rating for #34 YF-03, with the same release date of 3 April 1987. The shared date suggests these were visual variants of the same production. Yeti Factories released multiple intro configurations simultaneously, each ranked separately on intros.c64.org based on download popularity. No coder or additional credits are listed on CSDb. The group was founded in Germany in 1986. Despite running silent — with no SID output confirmed by disassembly — the intro earned one of the highest CSDb ratings in this collection, indicating that the visual design and scrolltext content resonated with the community. The practice of releasing multiple visual variants from a single codebase was uncommon but allowed groups to maintain visibility across cataloguing sites.
