Documented Pinball Software Archive
Alice Cooper's Nightmare Castle Pinball Software & Code Updates
As of July 29, 2026, Spooky's official support page provides an unversioned ACNC code package but no public release-note history. Because the machine is discontinued, the directly matching Pinside Game Archive details page qualifies as the permitted secondary archive. Its explicit changelog documents 16 releases from 1.0.6.16 through 1.1.0.5; the latter is the latest explicitly identified version.

Full dates use MM-DD-YYYY. When a source documents only a month or year, the page preserves that lower precision rather than inventing a day.
