# Indiana Jones and the Infernal Machine: a matching C decompilation

> This decompilation reconstructs C source for the 1.0 and 1.2 releases of Indiana Jones and the Infernal Machine. The game's original compilers rebuild source files, whose code, data and layout are checked against slices of a user-supplied Indy3D.exe; the resulting executable is checked by hash. The author reports a byte-identical rebuilt executable that includes small library sections and unused bytes copied from the original input.

## Requirements & limits

- **Prerequisites:** A supported original Indy3D.exe from version 1.0 or 1.2 is required for comparison and for original binary sections used in the build.
- **Prerequisites:** The setup uses the game's original compiler toolchain and the documented build pipeline.
- **Limits:** Small library sections and unused bytes are copied from the user-supplied executable.
- **License:** AGPL-3.0.
