>> “LLMs are Bad At Games”At making them?
Workflow
The user employed Claude Code to reverse-engineer a 1997 PC game for modern hardware compatibility. The workflow involved setting up a reverse engineering environment, decompiling code, and extending a shimmed DirectX DLL to enable headless execution via Windows Private Desktop. This allowed parallel game instances, while the agent mapped memory addresses and applied patches and memhacks to control gameplay. The user provided nudges and verified outputs using helper tools generated by the agent.
Reported result
The agent successfully ran the game headlessly and generated full level guides with screenshots zero-shot. However, the source does not provide specific measured metrics on performance or success rates beyond the qualitative description of the agent's capabilities. The user noted that the agent's ability to instrument the game contradicted the notion that LLMs are bad at games.
Human role
The original post does not say how a person stayed involved.
Limitations
The process relies on specific Windows features like Private Desktop and requires manual user intervention for verification and direction. The source does not detail the complexity of the game's original code or the specific technical hurdles encountered during decompilation. Success depends on the agent's ability to interpret memory structures and apply correct patches without breaking the game logic.
Try it
I want to use Claude Code to reverse-engineer a legacy PC game [replaceable: game name/year] to run on modern hardware. First, set up a basic reverse engineering environment and attempt to decompile the executable. If the game requires DirectX, extend a shimmed DLL to enable headless execution using Windows Private Desktop features to allow parallel instances. Map relevant memory addresses and game logic scripts. Create helper tools to visualize the game state for my verification. I will provide nudges and review the generated level guides and screenshots. Do not finalize any patches until I confirm the game runs correctly in a sample instance. If you encounter unknown memory structures, ask for clarification before applying memhacks.
