Corncob 3D reverse engineering

Research into Corncob 3D, the Personal Companion retail editions and The Other Worlds Campaign.

Start with Corncob Contemplated for an illustrated tour, interactive maps and models, and the music. The full research archive contains the evidence and working tools behind it.

To explore this checkout, open the analysis directory. The resource browser works directly from disk: artwork, cockpit screens, rotatable models, theatre maps, saved campaigns, recorded flights, presentations and lossless audio. The reading guide gives suggested routes through the reports.

For a playable reconstruction, see corncob-cpp. corncob-redux adds modern controls, higher resolutions and selected fixes. Both include the original game and Other Worlds.

Inside the archive

• Versions and installations identifies duplicate downloads, distinct builds and the confusing use of “Deluxe”. The normal-game reference is Personal Companion retail 3.42; the expansion reference is Other Worlds.
• Resource formats describes extraction and verification. Gameplay research covers movement, weapons, enemies, objectives and campaign rules.
• Audio exports, saved-state formats, model differences and the tower have their own reports.
• installs/ retains the source installations, including our old corncob/ save. install media/ contains extracted floppy filesystems and installers. Redundant archives and disk images were removed after verified extraction; their hashes and member inventories remain in the source-media record.
• tools/ contains the extraction and verification scripts. Publishing instructions cover the generated web archive and publish.sh.

The recovered original assembly source is preserved from the Initial Import commit of foone/Corncob3D, before later MASM compatibility edits, without Git metadata or the uploader’s README. The snapshot provenance records the upstream commit and SHA-256 of every retained file.

Part of The Lost Engines Project. Original game by Kevin Stokes and George Welch / Pie in the Sky Software; original music by Jim Collymore.
