Deep analysis of LONG0751, a variant of Colossal Cave Adventure, comparing the recovered 1982 game with Dennis Donovan's 1980 map to theorize about a missing intermediate version. The investigation uses room and object numbering as stratigraphic evidence to trace the game's evolution, revealing how puzzles like the well-bottom flute and helicopter arc were likely added incrementally. Key findings include vestigial treasures in the data file, differences in the recovered LONG0501 version, and insights into how state-changing objects were implemented through PROP values versus duplicate objects.
