AI Is Now a Magic Decompiler

Reverse engineering used to take 1 day per function. An AI agent just did 100+ while the developer slept.

Let me explain why this changes more than you think.

When you compile code, you lose everything human about it. Variable names disappear. Comments vanish. Structure flattens into raw machine code.

For decades, specialists spent entire days trying to reconstruct what the original code looked like. One function at a time. Manually.

Then a developer tried something different.

He pointed Claude at Super Smash Bros. Melee's compiled binary and built a simple loop with 3 agents:

• A Planner that picks which functions to decompile • Workers that generate candidate C code • A Judge that compiles the result and checks: does the binary match?

That last part is key. The compiler doesn't have opinions. If the recompiled binary matches the original, the code is correct. No human review needed.

It's like a lock and key. The original binary is the lock. The AI keeps generating keys until one fits perfectly.

And it worked. 20 functions merged, 80 more in review. The agents even ignored the tools they were given and built their own.

The numbers across the field are striking:

• A 1.1B parameter model trained on 33 million code pairs now outperforms Ghidra (the industry standard built by the NSA) by 136% • Developers report 96% match rate on first attempt for some function types • Claude successfully decompiled 27-year-old Visual Basic apps that specialized tools couldn't even parse

Finally, this isn't just about retro games. There are millions of lines of orphaned code running critical systems in hospitals, banks, and airports. Code that nobody alive fully understands anymore.

AI doesn't need to understand it. It just needs to reconstruct it and let the compiler verify the result.

The reverse engineer's job is shifting. Less time reading hex. More time designing the loop that lets AI solve the puzzle.
