The VMDispatcher was a massive switch-case statement, usually implemented as a jump table. Alex traced the jumps manually, careful to avoid the "dope code"—junk instructions inserted to obfuscate the flow.

This bypasses the VM entirely. You treat the VM as a mathematical function you don't need to decompile—only to invert. 2 This bypasses the VM entirely

Handler 0x42 looked interesting. It popped a value from the virtual stack, performed an XOR operation, and pushed it back. Handler 0x89 pushed a constant value. It popped a value from the virtual stack,

VMProtect's primary defense is its , which executes fragments of code using a different architecture embedded directly into the application.

He realized VMProtect was using "Mutation" mode. It wasn't just virtualizing the code; it was modifying the original x86 instructions before virtualizing them. It replaced standard instructions with functionally equivalent sequences of nonsense.
