Delphi Decompiler — DeDe: Overview, features, and usage

Delphi Decompiler (DeDe) is a long-standing tool for reverse-engineering executables produced by Borland/Embarcadero Delphi (and compatible) compilers. It helps recover readable Delphi-like source structures from compiled binaries, making it useful for analysis, debugging legacy apps, security research, and education. Below is a concise, complete primer covering what DeDe is, what it can and cannot do, how it works at a high level, how to use it, and legal/ethical considerations.
