GoKawiilDeveloper uses GPT-6.1 Sol Medium to decompile 2001 game Fast Food Tycoon 2
A hobbyist developer reverse-engineered the 2001 business simulator Fast Food Tycoon 2 by building an AI-driven agentic workflow powered by GPT-6.1 Sol Medium. The process used Ghidra to decompile over 4,000 functions from the game's executable, then indexed the resulting code in SQLite and paired it with live memory inspection via Windows' ReadProcessMemory API to map code to in-game behavior. The agent also patched the game's message handler to send it commands directly, allowing automated control of the interface.
GoKawiil's interpretation of the reporting above, not reported fact.
The project illustrates how large language models can now be chained into multi-step agentic tools that tackle traditionally manual, expert-driven tasks like reverse engineering legacy software. This suggests AI assistants are moving beyond code generation into exploratory technical work that combines static analysis, runtime inspection, and automated interface control. Such techniques could eventually lower the barrier for preserving, studying, or modding old software whose source code has been lost.
- A developer decompiled Fast Food Tycoon 2 using an AI agent built on GPT-6.1 Sol Medium.
- The workflow combined Ghidra decompilation, SQLite indexing, and live memory inspection via Windows APIs.
- The agent could also control the running game by patching its message handler, enabling automated UI interaction.
