Reverse Engineering Borland Delphi 7: A Decompilation Guide

  • IDR will parse the binary and list the classes (e.g., TForm1, TDataModule1).
  • Navigate to the "Forms" section. You will see the visual layout of the application.
  • Key Data: Look for the Events tab. Here you will see OnCreate, OnShow, Button1Click.
  • Export: Export the MAP file (Symbols) and the DFM files (Form resources).

for Delphi 7. This helps IDA recognize standard VCL library functions so you don't waste time reverse engineering code that Borland wrote. Search for "Borland":

Unlike C++ (which compiles directly to raw machine code, losing all metadata) or .NET (which is intentionally high-level and easy to decompile), Delphi 7 occupies a "sweet spot" for reverse engineering. borland delphi 7 decompiler

Form Recovery:

Most decompilers can perfectly extract .dfm files, allowing you to see the original UI layout, component properties, and menu structures. Reverse Engineering Borland Delphi 7: A Decompilation Guide

rich metadata

Delphi 7 (released 2002) is a classic Win32 compiler that produces native x86 code, but it embeds (called Debug Info , RTTI – Run-Time Type Information , and DFM resources ) that makes decompilation more feasible compared to C++ or Go binaries. IDR will parse the binary and list the classes (e

IDR

A "Borland Delphi 7 Decompiler" is not a single magic bullet application, but rather a category of tools like and DeDe that exploit the specific architecture of the Delphi VCL. While it is impossible to recover the exact original source code, the heavy use of RTTI in Delphi 7 makes it one of the most transparent compiled languages to reverse engineer, allowing analysts to reconstruct application logic with remarkable accuracy.

Event Handling

: It identifies "Published" methods and their associated events (like onClick ), providing commented ASM (Assembly) code for these specific routines.
