edx为字符编码基地址,每个字符占2C个字节,
edx+0 标志位 0x988798
edx+4表示字宽
edx+8表示字高
edx+C字宽
edx+10表示该字符点阵在内存的开始地址,
edx+14表示该字符前面的间距
edx+18表示该字符后面的间距
edx+1c一直为2
edx+20表示该字符点阵在内存的开始地址
edx+24表示该字符点阵在内存的结束地址
edx+28表示该字符点阵在内存的结束地址

这是本人从内存中导出字符N的点阵字库,一个字节表示一个点,数值越大,颜色越深
参数表
arg1:[arg1+10]+[arg1+C]*arg3+arg2*2存放缓冲区(应该就是屏幕显示区在内存的映像)基地址
arg2:字符串宽度 x
arg3:y
arg4:颜色
arg5:与颜色深度有关
arg6:与颜色深度有关
ecx:字符的编码基地址

本函数的核心是两层循环,从71B9A1开始就是循环体,整个换算过程是一个比较复杂的算法,可以简单表示为:
buf[x][y]=func(buf[x][y],zm[x/2][y/2])
buf:缓冲区二维数组,两个字节表示一个点
zm:字模二维数组,一个字节表示一个点
分析至此为止,下面是汉化的大致流程:
1.先从网上下载字库工具制作字库文件,格式为一个字节表示一个点,字体大小可以自己选择,
本人选的是16X16
2.修改原文件heroes4.exe的入口地址,开辟两段内存放字库和字符编码,并用全局变量保存
这两个指针
3.修改字库读取函数,把原来的字库和字符编码改成我们自己的。
(此游戏现已汉化成功)下面的附件是本人修改过的主文件和增加的dll文件、字库文件:
