A tiny bytecode VM interprets the license logic. Recover the handlers to beat it.

Linux · x86-64An original in-house crackme. Best run in your own analysis VM — it does not target any third-party or commercial software.
The challenge
VMLite ships a minimal register-based virtual machine and runs the validation as bytecode. To solve it you will identify the dispatch loop, map each opcode handler, and lift the program back to readable pseudocode — an accessible first taste of VM-based obfuscation.
