The platform also has some bugs, and some of the crucial features are still missing, like the text window currently does not include any syntax highlighting.

There are possibilities of adding new features in the newer versions. Repurchasing of the software will not be required as the newer version will be released since the software license is perpetual and source code is not provided as part of the distribution. If users want to create a project in Visual Studio, then one debug/fastlink option will scatter the bits of debug information throughout the LIB and OBJ files rather than storing the data in the PDB file.

Boomerang decompiler is an open-source, general, retargetable decompiler of machine code programs. The platform is developed to create an open-source, real decompiler for machine code programs. A decompile receives an executable file as input and attempts to create a compilable, high-level, maintainable source file that performs the same tasks. The decompiler function is the opposite of the compiler, which takes a source file and makes it executable.

A general decompiler usually doesn’t attempt to reverse every single action of a decompiler. Instead, the program input would be repeatedly transformed until the source code’s result is at a high level. The platform was intended to achieve a retargetable decompiler that can decompile different machine code files with modest effort, e.g., sparc-solaris, x86 Windows, etc. The program was built to be independent of the exact behavior of the compiler that is used chiefly through using robust techniques and transforming the semantics of individual instruction.
