Delphi Decompiler Dede Jun 2026
If you are analyzing a modern Delphi application (compiled with Delphi XE or RAD Studio 11/12), you might need to supplement or replace DeDe with:
is a specialized static analysis tool designed specifically for decompiling binaries compiled with Borland Delphi (and to a lesser extent, C++ Builder).
The analyst either reads the assembly directly inside DeDe or exports the metadata to an external debugger (like x64dbg) to set a breakpoint at that exact address. Limitations of DeDe
DeDe includes a built-in disassembler optimized for Delphi’s calling conventions (which heavily use registers like EAX , EDX , and ECX for passing arguments). Furthermore, DeDe can export a .map file or an IDC script. You can import this script into IDA Pro to automatically comment and name thousands of functions, instantly turning a confusing disassembly into an organized workspace. 5.

DeDe parses the Run-Time Type Information to build a comprehensive tree of all classes used within the executable. It reveals class inheritance, published methods, and internal structures, providing a high-level blueprint of the software's architecture. 4. Intel Disassembler with Delphi Comments
However, for , DeDe remains an irreplaceable hero. Thousands of companies still run Delphi 5, 6, and 7 applications on industrial control systems, bank kiosks, and medical devices. When the original developer left 15 years ago without handing over the source code, the IT department inevitably searches for "Delphi decompiler DeDe."
What was used to compile your target binary? Whether the binary is 32-bit or 64-bit ? If you are analyzing a modern Delphi application
This standard compilation strips away variable names and converts logic directly into assembly language. DeDe intercepts this by scanning for Delphi's unique .
DeDe is a tool of analysis, not theft. Professional developers use it to answer the question: "What does this legacy component do because the documentation is gone?" Malicious actors use it to crack software. The legality rests entirely on intent.
Between 2000 and 2015, countless malware families (e.g., early Zeus variants, many ransomware builders) were written in Delphi. Analysts use DeDe to rapidly locate the "network send" routine or the "registry persistence" function without stepping through thousands of instructions line by line. Furthermore, DeDe can export a

If you need to write a hook for an old Delphi DLL, DeDe reveals the exported function names and parameter expectations (through RTTI analysis).
