The Ultimate Guide to Decompiling LUAC: From Bytecode to Source

6. Practical decompilation workflow

  1. Identify Lua version and platform by reading LUAC header.
  2. Parse header and validate.
  3. Deserialize prototypes recursively into in-memory structures.
  4. Disassemble instructions into human-readable form.
  5. Build control-flow graph (CFG) per prototype. 6

    To the naked eye, a LUAC file looks like gibberish. But with the right tools and techniques, you can reverse-engineer that bytecode back into readable Lua source code. This process is known as decompiling. 1. What exactly is LUAC? The Ultimate Guide to Decompiling LUAC: From Bytecode
