Ultimate Delphi Decompiler by Medialight Corp. is a professional-grade analysis tool for inspecting and recovering high-level information from Delphi and C++Builder applications. Designed for software maintainers, security researchers, and digital forensics teams, it reconstructs readable Object Pascal–like pseudocode, classes, types, and resources from compiled Windows executables and libraries. Its fast, intuitive interface helps you navigate complex binaries, understand program structure, and accelerate troubleshooting, audits, and legacy code work.
Key features:
- High-level pseudocode: Recover Pascal-like routines with reconstructed control flow and data types where possible.
- Class and RTTI analysis: Identify classes, methods, VMTs, and interfaces using runtime type information when available.
- Form and resource recovery: Extract and rebuild VCL/FMX forms (DFM) and embedded resources for UI analysis.
- Cross-version support: Analyze 32-bit and 64-bit PE files compiled with various Delphi toolchains.
- Visual navigation: Call graphs, cross-references, and control-flow graphs to map program behavior quickly.
- Integrated disassembly: Low-level views with synchronized pseudocode, hex view, and symbol browsing.
- Commenting and renaming: Add notes, rename symbols, and organize findings to create a maintainable analysis workspace.
- Signature and pattern recognition: Automatically detect common libraries and frameworks to streamline reverse engineering.
- Search and filtering: Locate strings, constants, functions, and references across large projects.
- Export options: Save recovered forms, resources, and analysis artifacts for documentation or further processing.
Typical use cases:
- Legacy maintenance: Understand third-party or inherited Delphi codebases when original sources are missing.
- Security assessment: Audit binaries for vulnerabilities, backdoors, or suspicious behavior.
- Digital forensics and malware analysis: Examine Delphi-based samples with structured, readable output.
- Compliance and IP verification: Verify included components, licensing, and third-party dependencies.
System requirements:
- Windows 10/11 (64-bit recommended).
- Sufficient RAM and disk space for large binaries and projects.
Notes:
- Decompilation is an approximation; results vary with compiler optimizations, obfuscation, and stripped symbols.
- Ensure you have the legal right to analyze or decompile the software you inspect.
Ultimate Delphi Decompiler combines deep static analysis with a clean workflow, helping you move from opaque binaries to actionable insights quickly and responsibly.
