Decompiler V110194 — Delphi

Delphi stores RTTI for published methods and properties. v110194 excels at listing all published methods, class names, and inheritance hierarchies. This is invaluable for understanding an unknown binary's object structure.

| Tool | Delphi Version Support | Output Quality | Price | |------|----------------------|----------------|-------| | Delphi Decompiler v110194 | Delphi 1–11 Alexandria | Good (structured Pascal) | Paid | | IDR (Interactive Delphi Reconstructor) | Delphi 2–2007 | Fair (mixed Pascal/asm) | Free | | Ghidra (with Delphi plugin) | Limited | Basic (C-like) | Free | | DeDe (abandoned) | Delphi 2–7 | Poor | Free |

For modern Delphi targets (2010+), v110194 outperforms free alternatives significantly due to its RTTI v2 parser. delphi decompiler v110194

The latest version improves detection of Visual Component Library (VCL) hierarchies. Analysts report better reconstruction of form inheritance and component streaming data, which is critical when trying to understand GUI behavior without source access.

Original source (lost):

procedure TMainForm.CalculateTax(const Amount: Currency);
var
  TaxRate: Double;
begin
  if Amount > 1000 then
    TaxRate := 0.20
  else
    TaxRate := 0.15;
  lblTax.Caption := Format('Tax: %m', [Amount * TaxRate]);
end;

v110194 decompiled output:

procedure TMainForm.CalculateTax(Amount: Currency);
var
  TaxRate: Extended;
begin
  if Amount > 1000 then begin
    TaxRate := 0.20;
  end else begin
    TaxRate := 0.15;
  end;
  lblTax.Caption := Format('Tax: %m', [Amount * TaxRate]);
end;

As you can see, variable names (Amount preserved if RTTI available, but often becomes A1, A2) and comments are missing. The logic is correct, but types are sometimes inflated (e.g., Currency becomes Extended). Delphi stores RTTI for published methods and properties

The most famous Delphi decompiler was DeDe (Dark DeDe), written by a Russian team in the early 2000s. It could extract forms, events, and a skeleton of methods. Over time, other tools emerged: IDR (Interactive Delphi Reconstructor), Delphi Decompiler Dynasty, and proprietary scripts for IDA Pro or Ghidra.

It is within this evolutionary tree that v110194 appears—likely a specific cracked or custom build of an otherwise known decompiler (possibly a hacked version of DeDe 3.5 or an early IDR beta). v110194 decompiled output: procedure TMainForm

The tool analyzes imported symbols and internal references to rebuild the uses clause of each unit. It identifies standard units like SysUtils, Classes, Windows, and custom DCUs.
