"Gotcha," Marcus whispered.
The software offers two distinct decompilation modes accessible via its main toolbar. mode focuses on stack operations within a subroutine. When enabled, it unravels stack manipulations and converts commands like "push var_b push Rnd call %x1(%x2)" into the more comprehensible form "call Rnd(var_b)". When disabled, Native Code is output as raw assembly instead. Procedure Analyzer and Optimizer mode performs deep optimization on the generated listing—combining command blocks, removing unused variables and auxiliary structures, and producing output significantly closer to the original source code.
: For programs compiled in Native Code, it functions as a powerful disassembler. Recent updates have significantly improved accuracy for complex conditional logic, such as If/Else constructs, by using snapshot-based state isolation to prevent "state pollution" between code branches.
If a binary has been hardened using advanced commercial protectors, you may need to unpack the file manually using a debugger before loading it into VB Decompiler. Final Verdict

Security professionals use it to inspect closed-source applications for hidden vulnerabilities, undocumented backdoors, or malicious logic.
The tool is legal. The use case defines the legality.
