Borland Delphi 7 Decompiler

Analyzing old, proprietary applications to identify potential vulnerabilities.

Locates hardcoded strings to assist in finding specific logic.

It identifies "event handlers" (like OnClick buttons) by scanning the binary’s export tables and internal RTTI (Run-Time Type Information). borland delphi 7 decompiler

Open the target binary in or PEiD . Confirm it is a Borland Delphi compilation (usually identifiable by sections named .text , .data , and specific compiler signatures).

For Borland Delphi 7, the most solid and widely used decompilers are and DeDe . While they cannot fully restore original Pascal source code from machine code, they provide critical structural recovery for reverse engineering. Interactive Delphi Reconstructor (IDR) Open the target binary in or PEiD

Decompiling Borland Delphi 7: Tools and Techniques Borland Delphi 7, released in 2002, remains a cornerstone for legacy enterprise applications. Because Delphi compiles directly to native machine code, recovering lost source code—a process known as decompilation—is a complex task that typically yields assembly code rather than original Object Pascal. Popular Delphi 7 Decompilers

A legacy but highly popular tool specifically effective for normal Delphi Win32 binaries. It excels at extracting UI details and identifying event handler locations, though it often provides only assembly for the actual code logic. While they cannot fully restore original Pascal source

With DeDe, you can dump all project forms, see the exact components used on every screen, and extract a complete list of published methods and event offsets. This gives you a clear map of where the core business logic resides before you dive into a disassembler. 3. Revendipro

| Aspect | Disassembly | Decompilation | |--------|-------------|---------------| | Output | Assembly (mov, call, jmp) | High-level code (Pascal-like) | | Preserves | All instructions | Logic, event handlers, forms | | Loses | High-level structures | Original variable names, comments, some loops/if structures | | Delphi-specific | Can be annotated with Delphi RTTI | Recreates classes, properties, methods |
