AI Is Cracking Old Software: From GoldenEye to 2009 Call of Duty

Several reverse-engineering projects hit major milestones in recent weeks: GoldenEye 007, Super Smash Bros. Melee and Halo: Combat Evolved reached full decompilation, while 17 AI agents rebuilt a playable 2009 Call of Duty over three months using 600–700 billion tokens. The key is verifiable output: agents loop against a byte-for-byte pass/fail check.

• Super Smash Bros. Melee hit 100% decompilation after six years, with GPT-6 Astra closing the final stretch
• 17 Claude Code agents rebuilt 2009 Call of Duty in three months, burning 600–700 billion tokens
• Snowboard Kids 2 project made more progress in three weeks with AI than in the prior three months
• Ghidra, objdiff, N64Recomp and ReXGlue turned one-off hacks into reusable frameworks
