The Unexpected Effectiveness of One-Shot Decompilation with Claude

A developer shares their workflow for automating Nintendo 64 game decompilation using Claude in headless mode. The system uses a scorer to prioritize functions by difficulty, defensive tooling to prevent AI failures, and a bash driver to manage continuous execution. Over three weeks, this approach matched more functions than three months of manual work, with Claude Opus 4.5 successfully decompiling approximately 79% of functions. The workflow includes safeguards like automatic commits, retry logic, and token-efficient tools to handle extended unattended runs.
