If you do legacy Windows reversing, keep a copy in your toolkit. And if you’re a young reverse engineer, exploring Dede’s output side-by-side with a debugger will teach you more about Delphi’s internals than any book.
A legacy financial app uses TDateTime . You cannot find the source. DEDE shows you which procedures read from a date input. You locate the DateTimeToStr call in assembly, then binary patch the EXE to use a modern routine. Delphi Decompiler Dede
Delphi embeds form definitions as RCData resources in the .rsrc section. Dede parses these binary DFM streams, deserializing them back into a component tree. This gives the analyst the exact layout of the UI. If you do legacy Windows reversing, keep a
Which work better for Delphi XE and above? How to unpack a file before loading it into DeDe? You cannot find the source
: DeDe does not produce readable Object Pascal code. The "source" it provides for program logic is commented assembly (ASM), requiring knowledge of x86 architecture to understand.
Use the "Dump" feature to save the reconstructed DFM files or the list of identified procedures for further analysis in an editor like IDA Pro or OllyDbg.
Delphi stores form definitions in .dfm files. At compile time, these are linked as binary resources. DEDE extracts this resource, reverses the binary streaming format, and outputs a readable .dfm text file. This file can be loaded directly into the Delphi IDE.
