Delphi Decompiler — Dede

: It presents published methods in well-commented Assembly (ASM) code. These comments often include references to strings, imported function calls, and components, making the low-level code much easier to read than raw hex.

These are more specialized tools. H2DRes focuses on recovering resources (icons, strings, forms), while H2Viewer focuses on class hierarchies. Neither is a full decompiler, but combined with IDR, they replicate DeDe’s functionality.

Delphi uses .dfm files to define the visual layout of windows, buttons, text fields, and menus. DeDe can fully extract these forms and display them visually or as text. This allows you to see exactly how the user interface is structured, complete with the internal names of every button and input field. 2. Event Handler Mapping delphi decompiler dede

Delphi is strictly object-oriented. DeDe parses the internal Runtime Type Information (RTTI) embedded by the Borland compiler. It reconstructs the entire class hierarchy used in the binary, revealing class names, inherited properties, and internal object types. 4. Disassembler and Assembler Comments

If you are reversing a modern Delphi application, DeDe might fail to parse the file. Analysts today rely on updated tools that built upon the foundations DeDe laid down:

The Ultimate Guide to DeDe: The Legendary Delphi Decompiler Reverse engineering compiled binaries is a complex art. When dealing with applications built using Borland Delphi (now Embarcadero Delphi), standard decompilers often fall short. Delphi uses a unique object-oriented structure, custom calling conventions, and a distinct event-driven architecture. DeDe can fully extract these forms and display

Given the closure of Embarcadero’s old compiler team and the rise of obfuscation tools (like ArmDot for Delphi), the golden age of simple decompilers like DeDe is fading. Modern Delphi authors can now strip RTTI, encrypt resources, and mangle names, making DeDe useless against protected binaries.

Use the menu if you need to manually analyze a specific memory offset (RVA) not automatically found. 3. Critical Limitations
