Export the parsed symbols as a MAP file. Load your target executable into a more powerful debugger/disassembler (like x64dbg or IDA Pro) and apply the MAP file to instantly populate the workspace with the function names discovered by DeDe. Limitations and Modern Alternatives

Despite its many strengths, DeDe has significant limitations that users must understand. Perhaps most critically, DeDe was never intended to produce compilable source code. Its output is informative rather than executable, serving as a map rather than a reconstruction. This is not a deficiency of DeDe specifically but a fundamental constraint of Delphi decompilation: the compilation process discards much of the high-level semantic information that would be necessary for perfect reconstruction.

DeDe was designed for 32‑bit Win32 Delphi applications. It cannot parse 64‑bit Delphi executables, which are increasingly common in modern development. As of 2026, no version of DeDe has been adapted for x64 [citation needed].

Together, DeDe, IDR, and Delphi Decompiler are often referred to as the "Delphi Anti-Compilation Three Musketeers," a carefully curated collection specifically designed for reverse engineering, software analysis, and security research targeting Delphi applications.

This moves the tool from a simple "disassembler with a GUI" to a true "code comprehension engine," specifically tailored to the nuances of the Object Pascal ecosystem.

Dede has various uses, including:

However, DeDe is not a magic “source code recovery” tool. It produces assembly, not Pascal, and it has been obsolete for nearly two decades. Modern reverse engineers working with contemporary Delphi binaries will find far more capable alternatives in , Ghidra with Delphi scripts, or IDA Pro . For 64‑bit executables, DeDe is simply not an option at all.

to identify malicious behaviors in Delphi-based binaries.

Modern versions of these suites have vastly improved their native Delphi RTTI parsing capabilities. Custom scripts can often replicate DeDe's map generation.

While DeDe remains a landmark tool in reverse engineering history, it has notable limitations in the modern era:
