Catalogue
Every known title, in order of release. Each year is the one printed on the game’s own loading or title screen, with two exceptions: no copy of Forbidden Valley survives, so it is placed with The Secret of Flagstone Manor, and King Solomon’s Mines prints no year, so it rests on the October 1984 advert. Each game’s page shows the evidence.
