Borland Delphi 7 Decompiler

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

Borland Delphi 7, released in 2002, is widely regarded as the "golden age" of the Delphi programming language. It was stable, powerful, and produced highly optimized native x86 code for Windows. Because of its popularity, a massive amount of commercial and shareware software was written in Delphi 7.

A "Delphi 7 Decompiler" refers to specialized reverse engineering tools designed to translate the compiled machine code (binary) of a Delphi application back into a readable format—ideally Object Pascal source code. Unlike .NET or Java applications, which compile to intermediate bytecode that is easily reversible, Delphi compiles directly to machine language, making decompilation a complex and imperfect science. borland delphi 7 decompiler

Run IDR and load your .exe. IDR will automatically:

Expected output: You will instantly see a tree of TForm1, TDataModule2, etc. Open the target binary in CFF Explorer or PEiD

Several tools are considered industry standards for this version.

Status: Active Best for: Extracting raw resources and forms. While not a standalone decompiler, the Lazarus IDE includes tools to parse Delphi forms. Used in conjunction with binutils (objdump), you can manually reconstruct a project. This is the "archaeological" approach. Expected output: You will instantly see a tree

For serious reverse engineering, IDA Pro with a Delphi signature file (FLIRT) or the Hex-Rays Decompiler is essential.
