编译后，把_TextOut的汇编代码植入游戏（可用ODBG的二进制复制粘贴功效），并修改相关的api调用。
其中int x, int y, char *string, COLORREF color,lpDDSBack都已经阐发出，而hfont需要在游戏开
始时用CreateFontA创立，偷偷生存在数据段的末尾，竣事前用DeleteObject析构。
代码:--------------------------------------------------------------------------------

--------------------------------------------------------------------------------
然后修改原来的字符串输出函数：
代码:--------------------------------------------------------------------------------
0057E5E0 - E9 9B5A0B04 jmp war_in_t.04634080 ; 原： mov eax, dword ptr ds:[4605D10]
--------------------------------------------------------------------------------
跳到这里，调用我们本身的_TextOut：
代码:--------------------------------------------------------------------------------
04634080 8B0D 080B0E04 mov ecx,dword ptr ds:[40E0B08]
04634086 FF71 10 push dword ptr ds:[ecx+10] ; 颜色
04634089 FF7424 10 push dword ptr ss:[esp+10] ; 字符串
0463408D FF7424 10 push dword ptr ss:[esp+10] ; y
04634091 FF7424 10 push dword ptr ss:[esp+10] ; x
04634095 E8 66020000 call war_in_t.04634300 ; _TextOut
0463409A 83C4 10 add esp,10
0463409D C3 retn
--------------------------------------------------------------------------------
至此，游戏已能正常显示中文。
