Clone a classic game by decompiling it with subagents
Opus 5.5 decompiled SimCity 2000 with Ghidra using 27 subagents, then verified 10,000 game days via a Unicorn emulator.
Prompt for your agent
Goal: Build a faithful modern replica of an old game from its original binary. Setup: agents used in source: Claude; tools/MCPs stated: Ghidra, Unicorn, GPT Image 2. Steps: 1. Prompt: “create a typescript webgl low-poly version (full replica of game logic) of <game>. the original is available here for inspection”. 2. Let it decompile with Ghidra and translate native code function by function using subagents. 3. Follow up: “make sure all aspects of the game is implemented correctly and accurately” — it built an emulator harness to compare game state over 10,000 days. 4. Polish; generate 3D/vector assets in code and bitmaps with an image model. Rules: ask me before anything irreversible (sending, posting, paying, deleting); don’t invent data, results or tools I haven’t given you; tell me what you couldn’t verify.
