If you are analyzing a program to find where a password validation happens, navigate to the tab. Look for the main form (usually Form1 or MainForm ) and locate a button named btnRegister , btnOK , or Button1 . DeDe will show you the exact memory address for the OnClick event handler. Step 3: Exporting to a Disassembler
To help me tailor this information or provide further technical steps, tell me:
It acts more like an interactive disassembler and metadata extractor than a true decompiler. It will not output human-readable Object Pascal loops or conditional statements.
: You can load .dsf files (DeDe Symbol Files) via File | Load Symbol File . These help DeDe identify and comment on exports from BPL libraries, similar to FLIRT signatures in other tools. delphi decompiler dede
class DelphiDecompiler: """Main decompiler class for Delphi executables"""
is a specialized static analysis tool designed specifically for decompiling binaries compiled with Borland Delphi (and to a lesser extent, C++ Builder).
DeDe was built during the peak of Delphi 3 through Delphi 7 (the late 1990s and early 2000s). It struggles significantly with modern 64-bit Delphi binaries, Unicode string formatting introduced in newer Delphi versions, and modern cross-platform frameworks like FireMonkey (FMX). If you are analyzing a program to find
# Pattern for Delphi method references method_patterns = [ rb'\x68([\x00-\xFF]4)', # push address (DELPHI) rb'\xB8([\x00-\xFF]4)', # mov eax, address ]
DeDe first loads the target executable into its own memory space before analyzing it, which allows the tool to partially decompile executables that other tools reject. While this does not guarantee full recovery from aggressive protectors, it is a useful feature for dealing with moderately obfuscated files.
When you drop a file into DeDe, it scans the binary for Delphi's unique class structures. It identifies every button, text box, panel, and menu item used in the program. 2. Resolving Event Handlers Step 3: Exporting to a Disassembler To help

The Delphi Decompiler Dede is a classic in the reverse engineering toolkit. Despite the existence of more advanced, modern decompilers, Dede's ability to quickly parse DFM files and provide structured, commented assembly code makes it an essential tool for anyone working with older Delphi applications or conducting fast reconnaissance on a Delphi binary.
