Beyond standard executables ( .exe ) and libraries ( .dll ), the decompiler can also process Delphi Compiled Units ( .dcu ) and Borland Package Libraries ( .bpl ). .dcu files are the intermediate object files created by the Delphi compiler for each unit (source file). Decompiling these can often yield a much closer representation of the original Pascal code than decompiling the final .exe .
: While often flagged as "malicious" by some automated sandboxes due to its deep system hooks, it has historically shown a 0% detection rate
Reconstructs class hierarchies and object inheritance structures. delphi decompiler v1.1.0.194
It populates a visual side-panel tree that mimics the original Object Pascal class hierarchy, allowing users to browse components logically. The Technical Challenge of Delphi Decompilation
The user runs the decompiler executable. Once the interface loads, they navigate to open the target file—a Delphi-compiled .exe or .dll that they intend to analyze. The tool will then begin its initial parsing of the file. Beyond standard executables (
It is illegal to use such tools to steal proprietary code, bypass licensing mechanisms, or create derivative works that violate software licenses.
Organizations frequently lose original source code due to hardware failures or missing backups. Version 1.1.0.194 allows developers to recover forms and core algorithms from old corporate applications. : While often flagged as "malicious" by some
Installation & UI
: While highly effective for older versions (Delphi 2-7), it is generally less efficient with modern Delphi releases. For more complex disassembly, researchers often use it in tandem with tools like IDA Pro via available bridges.
