This article dives deep into the world of Delphi decompilation, exploring the architecture of the binaries, the specific tools required, and the reality of what is possible when you attempt to turn an .exe back into Pascal code.
If you only download one tool from this list, make it IDR.
files and produce commented assembly code that highlights string references and class method calls. VB Decompiler: Despite its name, this tool supports decompiling Delphi
Local Variable Names: Variables like "i" or "tempCount" are lost; they become registers like EAX or EBX.
Delphi 7 applications are heavily reliant on the VCL. The VCL is a hierarchy of objects (TObject -> TPersistent -> TComponent -> TControl -> TWinControl -> TButton).

When a decompiler sees a block of code using TButton.Click , it doesn't just show you assembly; it reconstructs the Pascal event handler.
