虚拟光碟防复制技术破解

下指令bpx createwindowex //下中断点

按X键回到桌面运行程序，这时会被Trw2000拦截到。

下指令bc * //清除断点

下指令pmodule //直接跳到程序的领空

按F10来到下面,

看看那里可以跳过这里。

上面00408BE4 JNA NEAR 00408C6D 好像可以跳过它耶!!!!

重新下断点bpx 00408BE4

按X键回到桌面运行程序，这时被Trw2000拦截到。

当光标走到00408BE4 JNA NEAR 00408C6D，

打入命令 CODE ON 记下指令码

下指令A 写入汇编代码
将 00408BE4 JNA NEAR 00408C6D
改 00408BE4 JNZ NEAR 00408C6D

又可以进入程序了。

整里一下，用Ultraedt打开MGR.EXE

找到OF 86 83 00 00 00

改成0F 85 83 00 00 00

可以跳过试用过期的对话框，订购软件的对话框进入程序。

但是，会弹出软件是评估版的对话框。我不知道如何用Ultraedt
将00408D87 744C JZ 00408DD5
改00408D87 744C JZ 00408D97
跳过此对话框。或者有其他更好的方法。望各位大侠指点。多谢！！！
