Stronghold Decompilation

About

DeSt is a work-in-progress decompilation of the 1993 AD&D Stronghold game for DOS. Its goal is recovering the original code in a form that can be compiled with Borland C++ 3.0. So far it has decompiled a small part of the init code and mapped most of the asset init code.

Status & roadmap

• Open tasks include fixing skyline palettes, entity frame rect markers and RLE encoding for PBM LBM files, then decompiling the rest of the game.

Modding & tools

• The repository includes a Ghidra project file, an ungrab utility that recovers files from the English STRONG.DAT, and an mzap utility that converts the Borland overlaid STRONG.EXE into a plain MZ format loadable by Ghidra and IDA.

Additional notes

Assets

The raw asset files (LBMs, VOCs and others) have been recovered and can be assembled back into the STRONG.DAT file with the st.exe grab command.
