下载地址： http://bmzhao.wx-e.com/mjexe.zip
软件大小：1.22MB
难度：非明码比较，但难度简单
破解者:青锋剑客[DFCG][FCG]
破解工具：FI
W32Dasm V10增强版
Ollydbg v1.07b 汉化版
MASM7
以下是破解过程，不对的地方请批评指正：
1、使用FI查一下，发现没有加壳，这下又省了一步。
2、用W32Dsm V10增强版反编译,工具栏 → “参考” → “字串符数据参考”
发现串式"注册失败",双击他：
双击他后来到这里

3.现在开始动态跟踪并追出注册码来。启动Ollydbg v1.07b 汉化版。F3键打开mj.exe。在代码窗口找到00408B55，F2键在此下断点。
4.按F9键运行，启动程序后会弹出注册窗口，点"马上注册" → 我的机器码为"607852289" →在注册码处输入"87654321" → 点注册 → 程序中断于刚才我们所设的断点004BB730处，F7跟进，来到如下：
