# 這他媽的太不真實了！AI 代理正在用一無所有重建一款 1996 年的 Windows 遊戲

一篇 X 貼文描述了 AI 代理如何使用 REA（逆向工程 MCP）從 DX-Ball 可執行檔案中復原函式，逐個函式重建 C 版本，並與原始 x86 程式碼進行逐位元組比較。

## Description

作者詳細介紹了單個函式的復原過程：分析函式 0x406400，追蹤呼叫者以推導螢幕位置公式，從 .exe 中讀取兩個常數，並使用 3,205 個測試案例和 1996 年時代的編譯器進行位元組完全相同的重新編譯來驗證重新實作。貼文報告了 55 個函式被重寫，45,380 次檢查，33 個位元組完全相同的函式，並指出 REA 覆蓋 23 種目標類型，透過 npx rea-agents 一鍵設定。未提供儲存庫連結，也未說明逆向原始商業遊戲的權利。

## Original README

THIS IS F*CKING UNREAL! AI AGENTS ARE REBUILDING A 1996 WINDOWS GAME WITH NOTHING BUT THE .EXE

the game is DX-Ball. no source code. no docs. just the original executable

and REA, the MIT-licensed reverse engineering MCP sitting at 238,000 stars on GitHub

the goal: a clean, maintainable C version of the whole game, recovered 1 function at a time

here's 1 function, start to finish

question: when a brick breaks, which speaker plays the sound?

the agent asked REA 3 things:

→ analyze_function 0x406400 - the decompiler said the function was empty. the raw instructions showed a hidden integer input
→ follow the caller - the brick-hit code turns a tile into a screen position: 20 + 30 × tile_x
→ read_bytes - 2 constants buried in the .exe decode to 1.5625 and 500.0

the whole formula:

pan = (x × 1.5625 − 500.0) × scale

-500 on the left edge. 0 in the middle. +500 on the right

then it had to prove it wasn't guessing:

> 3,205 test cases run against the original x86 code
> every position from 0 to 640, at 5 pan scales
> recompiled with the 1996-era compiler: all 63 bytes identical

the project so far:

> 55 functions rewritten in C
> 45,380 checks against the original
> 33 functions that compile byte-for-byte the same

and it's not just old games. REA covers 23 target types: native binaries through Hopper, Ghidra or IDA, Electron apps, .NET, Android APKs, websites, firmware, network captures

1 command to start:

npx rea-agents setup

then hand your agent a binary you're allowed to inspect and paste this:

"Use REA to recover 1 function from this executable

1. Analyze the function and its callers. Show the instructions behind every claim, not just the pseudocode
2. Read and decode every constant or global it depends on
3. Write a C version with the same inputs and outputs
4. Build a test that runs the original and your version across the full input range. Report every mismatch"

start with 1 small function you can fully verify

the decompiler said empty. the bytes said otherwise.
