AI agents can now drive Ghidra and IDA to rebuild games

When a normal mod isn't enough, the next step is reverse engineering → rebuilding: decompile the game's executable, understand how its systems work, then have an AI help reconstruct them in a new codebase.

The toolkit is getting agent-friendly. Ghidra MCP connects Ghidra's analysis features to AI agents. IDA MCP is an official Hex-Rays integration, so a major commercial reverse-engineering vendor now supports agent workflows directly. For managed games, ILSpy handles .NET assemblies. Cpp2IL helps with Unity IL2CPP builds.

Decompiling does not hand you a clean, compilable source project. The realistic loop is: reverse engineer → understand systems → reconstruct → compile → test → repeat. AI speeds up each pass, especially the tedious work of reading decompiled output and drafting replacement code. A large rewrite is still a real engineering project, though.

The usual caveat applies: check the game's license and EULA before you decompile or redistribute anything.

Why it matters: AI agents plugged into reverse-engineering tools shrink the time from "how does this binary work?" to "I have a working rebuild", though they don't remove the engineering.
