A developer's son picked up Compton's 3D World Atlas Deluxe — a Windows 95-era educational CD-ROM — in a thrift store in Port Townsend, WA. The disc technically ran on Windows 11 but kept trying to reach an online service that vanished long ago.

Instead of giving up, he built a user-local compatibility layer around the original lawful 3DATLAS disc. The videos, encoded with the ancient Indeo codec, were converted to Microsoft Video 1 while keeping the original PCM audio. The dead Online button now opens a local mirror rebuilt from Internet Archive captures of the old Atlas and Compton's sites, with dead forms rendered harmless. A small x86 compatibility shim replaced the obsolete WonderLink component — a deliberately safer choice than downloading a random DLL.

The installer grew from a script into a full tool with logs, archive downloads, video conversion, shortcuts, checksums, and rollback behavior. One bug, where the new config landed next to the original 1998 DLL and triggered a confusing error, led to staged installation: components are verified by SHA-256 and only a complete result is published, leaving a previous working install untouched on failure.

Two shortcuts ship: a normal windowed mode and the atlas's own Superplay fullscreen mode, which preserves the original 4:3 artwork. The project even got Pester tests for installer helpers, Node.js tests for the archive synchronizer, PowerShell parsing checks, and a GitHub Actions pipeline that builds the x86 shim, the installer, and publishes release v1.2.2 with a checksum. The toolkit contains no commercial Atlas data; the original disc must remain mounted while the program runs. The result: globe, movies, games, and flag quiz all work — an absurd amount of engineering for a thrift-store CD, and entirely worth it.
