My friend and I were able to give claude a (no longer updated) unity arcade game. It decompiled it and created a one-to-one typescript port so it can run in the browser and now we're adding multiplayer support (for personal use, don't worry HN - we won't be distributing it). I'm very excited for what AI can do for legacy software.
I agree, I tried RE using multiple tools connected to MCP and a agent, it was tasked to recreate what the source code might have looked like from a binary and what possible vulnerabilities there could be. It did a incredible job when I compared it to the actual source.
