[AI Minor News Flash] Reviving the Legendary Puzzle Game ‘Chromatron’ from 20 Years Ago with AI and Ghidra!

📰 News Summary

• Successfully ported the 2000s puzzle game ‘Chromatron’ to the latest Apple Silicon and WASM (WebAssembly) environments.
• Leveraged the NSA-developed reverse engineering tool “Ghidra” alongside cutting-edge AI models like Claude 4.6 and GPT-5.3.
• Achieved “Vibe-porting,” reconstructing source code from old machine language with the help of AI, despite minimal experience in binary analysis.

💡 Key Points

• Model Evolution is Key: The early model (Opus 4.5) struggled with hallucinations (generating false code), but the latest Opus 4.6 and GPT-5.3 have dramatically improved accuracy, producing functioning code with minimal guidance.
• Diverse Approaches: Experimented with multiple tech stacks, including a decompiler called “m2c” to convert PowerPC machine language to C, and rewrites into Rust, combining AI with various techniques.
• Verification through Image Comparison: Since AI tends to assert “it’s the same,” they implemented pixel-level comparisons of screenshots to provide strict feedback and enhance fidelity.

🦈 Shark’s Eye (Curator’s Perspective)

AI has carved a path into the once highly specialized domain of code recovery from binaries! What’s particularly fascinating is how it has transcended the “language barrier.” The implementation of converting old C++ binaries into modern Rust code is simply astounding. The process of prompt engineering, where AI reads binaries and fills in the gaps, feels almost archaeological in its romanticism!

🚀 What Lies Ahead?

We’re entering an era where many classic software titles and legacy systems, previously confined by old architectures, can be automatically restored to “modern code” quickly and affordably with AI.

Dissecting and reviving old games with AI? That’s the ultimate summer research project! I want to upscale those old shark movies to 4K with AI too! 🦈🔥

📚 Terminology

• Ghidra: An open-source reverse engineering tool released by the NSA that can analyze binaries (executable files) and revert them to a form close to source code.

• WASM (WebAssembly): A program format that allows code to run in browsers at near-native speeds, making it possible to play old games without installation.

• Recompilation: The process of analyzing a binary created for one environment and restructuring the code to run in another environment (in this case, on Apple Silicon).
