Overview
Delphi Decompiler v1.10194 ("v1.10194") is a native-code analysis tool for reverse-engineering Delphi and other Windows PE binaries. It focuses on reconstructing high-level Delphi code constructs, symbol-like identifiers, and program structure from compiled executables and DLLs. This release emphasizes improved accuracy for class, VMT and RTTI recovery, enhanced control-flow reconstruction, and more robust handling of optimized code.

Conclusion
Delphi Decompiler v1.10194 brings meaningful advances in reconstructing Delphi binaries, particularly around RTTI and class/VMT recovery, making reverse-engineering Delphi applications faster and producing more readable output; however, it remains a best-effort tool and benefits from complementary manual analysis and corroborating runtime investigation.
If v110194 fails to produce meaningful code, the reverse engineering community generally recommends the following modern alternatives:
Summary: Delphi Decompiler v110194 "Better" is a legacy tool best suited for old educational software or abandonware created in the late 90s/early 2000s. For modern binaries, switch to IDR. Overview Delphi Decompiler v1
Corrupted or missing DFM resources? v110194 doesn't just dump binary DFM. It cross-references:
The output is a reconstructable .dfm that can be dropped back into the IDE. I’ve personally resurrected a 2003 Delphi 7 app with 37 forms from a stripped executable. Two forms needed manual fixing. That’s insane.
Delphi uses specific memory management (FastMM predecessors) and calling conventions (register / Borland FastCall).
Yes, if:
No, if:
Most free decompilers still struggle with Unicode string formats and the new TControl vtable layouts. v110194 explicitly added signatures for:
This tool does not usually produce re-compilable source code. It produces Human-Readable Analysis.
Example Output:

call TForm1.Close ; VCL Call
