DeDe was primarily designed during the golden era of Borland Delphi (versions 2 through 7). It struggles with modern 64-bit Delphi binaries, unicode-enabled versions (Delphi 2009 and later), and applications built using the cross-platform FireMonkey (FMX) framework.
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
In a standard debugger like x64dbg, a button click looks like a jump to a random memory address. DeDe looks at the internal VCL (Visual Component Library) structures and tells you exactly which function triggers when a user clicks Button1 . 3. Reconstructing the DFM

As of 2026, DeDe is primarily found in software archives and community forums rather than official developer sites. For modern reverse engineering of Delphi binaries, researchers typically use a combined approach with more advanced tools: IDR (Interactive Delphi Reconstructor) Load your target executable into a more powerful
DeDe’s feature set is tailored specifically to the Delphi ecosystem, providing capabilities that generic tools cannot easily replicate. Below are its most important functions.
