规则
我并不介意你怎样破解它,但最好做一个注册机或给它加入注册机功能。

1)Open target in Olly and do a search for all strings.
1)用OD打开它并查找字符参考。
2)Find the string "Password: " and double click it.
2)找到"Password: "并双击它。
3)Eight lines after it you have a CMP of a hard-coded serial.
3)分析它下面的代码发现:固定明码比较注册码是否正确然后跳转。(多往下看看就看出来了。)
4)Copy the value to the clipboard and Hex -> Dec convert it and vwalla.
4)把明码(16进制)转成十进制。结果=2140661100
5)You already got the serial, so why your reading 5) ? :P
5)哈哈,你已经拿到注册码了,因为你已经看到第五步了。:P
Target cannot be keygenned coz there is no algorthm,
but if you insist of Self-Keygen you can write the Converted value
into a code-cave "Password: (hint:2140661100)" and change the address
in 0040152E to the address of the "Password: (hint:2140661100)" string
