"竹影棋友"围棋程序注册鸡 (2千字)

四月初在即将离开我的上一家公司--东大阿尔派深圳分公司的时候新来一位同事嚷着要和我下围棋. 找来找去发现只有用"竹影棋友围棋程序"可在局域网下棋. 当时在"盗亦有道"上下载了破解版, 在软件中也可以看到"dyyd"字样. 可是当下到250手时, 软件弹出"共享版, 只能下250手, 然后中断连接". 让我一盘大优的棋没有下完. 如此"有道":(
只得祭起wdasm8.93, (顺便解决了wdam不能正确显示种文字串的一个小bug) 结合SoftIce发现了竹影棋友的注册算法. 考虑到这程序有2年没有更新, 为此贴出其注册机的完整程序. 这也正是当时我离开论坛时答应要做的
