It can export .MAP files or IDC scripts, which are vital for loading into more powerful tools like IDA Pro or x64dbg to provide symbols and context. 3. Use Cases in Reverse Engineering
: When original source code for a legacy Delphi system has been lost, DeDe can provide sufficient information to understand application behavior, recover form layouts, and identify critical functions. This can be invaluable for organizations maintaining decades-old applications with missing documentation.
In this article, we explore what Dede is, how it works, its features, and how it fits into the landscape of modern Delphi reverse engineering in 2026. What is Delphi Decompiler Dede?
DeDe is a specialized reverse engineering tool designed specifically to parse and reconstruct the internal structure of Delphi (and C++ Builder) executables.
DeDe does not give you a "Compile" button to recreate the lost source project. Instead, it provides a functional architectural map:
Are you trying to from a specific legacy file, or
What is your primary ? (e.g., malware analysis, recovering lost code, security auditing)
The NSA’s is a world‑class, open‑source reverse‑engineering framework. Out of the box, Ghidra treats Delphi binaries as generic x86/x64 code, missing the Delphi‑specific structures. However, community scripts (such as dhrake ) can load the symbol files generated by IDR or manually reconstruct VCL information, bringing Ghidra close to the level of domain‑specific tools.
DeDe analyzes the binary signatures to determine which version of Delphi or C++Builder was used to compile the file (e.g., Delphi 3 through Delphi 7).
If you need to write a hook for an old Delphi DLL, DeDe reveals the exported function names and parameter expectations (through RTTI analysis).
