文章分析的程序和外挂可以本站下载区下载
程序说明：
以Windows消息循环的方式来分析这个游戏，先用PEID查看，发现什么也没有，再用OD载入发现没有加壳。从代码的风格上来看不是用VC，BC或汇编写的可能是其它的编译器编译的。
流程概述：
1． 解密数据，注册窗口
2． 创建窗口
3． 消息循环，等待
4． 在消息空闲的时候，开始游戏的数据，控制处理
5． 如果收到退出消息就退出进程
程序分析：
00402020 > $ 53 push ebx
00402021 . 83C4 E4 add esp, -1C
00402024 . 6A 00 push 0 /pModule = NULL

0040202B . A3 D8694000 mov dword ptr [4069D8], eax
得到程序实例句柄。
00402030 . E8 D3010000 call 00402208
跟入此call：
0040220E |. E8 6F260000 call <jmp.&WINMM.timeGetTime>
00402213 |. A3 005C4000 mov dword ptr [405C00], eax
得到系统时间放到全局变量里面
0040221A |. BE B0634000 mov esi, 004063B0
0040221F |> 8B06 /mov eax, dword ptr [esi]

0040222A |. 83FB 0D |cmp ebx, 0D
0040222D |.^ 7C F0 \jl short 0040221F
将一些文本字符串数据解密

004022E7 |. 6A 00 push 0 |hInst = NULL
004022E9 |. E8 5E250000 call <jmp.&USER32.LoadCursorA> \LoadCursorA

004022F4 |. 894424 1C mov dword ptr [esp+1C], eax
004022F8 |. 33D2 xor edx, edx
004022FA |. 895424 20 mov dword ptr [esp+20], edx
004022FE |. C74424 24 565>mov dword ptr [esp+24], 00405C56 ASCII "wcTKKN"
00402306 |. 54 push esp /pWndClass
00402307 |. E8 22250000 call <jmp.&USER32.RegisterClassA> \RegisterClassA
可见是注册窗口类，00402318就是消息处理函数了。

创建并显示窗口了，通过参数可以看出游戏窗口的信息。

消息循环
后面的调用WaitMessage附近是一些游戏的逻辑。
再向后才是最重要的地方之－：
004020FB . E8 00130000 call 00403400
关于call 00403400函数的作用是控制游戏和核心，下几篇详细分析
00402112 . 51 push ecx /ExitCode
00402113 . E8 EC260000 call <jmp.&KERNEL32.ExitProcess> \ExitProcess
退出进程
