Group
Nostalgia — founded February 1995

Titled "Stableraster" on CSDb and catalogued as release #212165, this Nostalgia crack intro was released on 18 December 2021 and carries a CSDb rating of 8.58/10. S!R handled the code while 6R6 — Glenn Rune Gallefoss — composed the original SID tune "Stableraster," preserved in the HVSC. The title likely references the stable raster technique used in the intro's visual effects — a programming method for producing flicker-free raster bars on the C64's VIC-II chip. Nostalgia was founded in February 1995 and has maintained continuous activity for over two decades, an exceptional run in the C64 scene. Doc Snyder's page documents the group's extensive catalogue, with S!R and 6R6 forming a core partnership across many productions. The intros.c64.org listing attracted comments as recently as 2023 from Fungus — a known Nostalgia member — indicating the group's continued presence in the community. The group's website at n0stalgia.org serves as their online hub.
