The Long Tail of LLM-Assisted Decompilation

Summary

The article details the author's experience using LLMs to decompile Nintendo 64 games, focusing on workflow evolution and tooling. It highlights the shift from difficulty-based prioritization to similarity-based methods and the use of specialized tools. The author also discusses challenges with permuters and the importance of code cleanup.

Key Takeaways

1. Prioritizing similar functions significantly improved decompilation progress by leveraging Claude's ability to recognize and reuse patterns across them.
2. Specialized tooling, such as gfxdis.f3dex2 for disassembling hex values into specific commands, greatly enhances Claude's performance in domain-specific scenarios.
3. Permuters, while intended to complement LLMs by brute-forcing the final few percent of a match, often introduce noise and instability, leading to decreased overall progress.
