标题: JEB 2.0.6 52pojie破解方案简评

https://scz.617.cn/misc/201607281139.txt

52pojie上JEB 2.0.6的破解方案没有利用注册机制，修改了多处。好处是不用区分类
型，各种版本都可以照此暴破，全覆盖。看雪上的破解方案利用了注册机，只修改
了4字节整型。两种破解方案都不符合我的美学观点，单就这个目标版本而言，推荐
使用后者。

此处就52pojie破解方案简评之，主要是给JEB破解初学者看的。我不给这种破解方案
背书，下面只有事实罗列，没有各种画外音评价；但我建议初次接触JEB破解的人照
此暴破一遍练手。

我是个好人，此处请点一万次赞，谢谢。

PS，凡是过往给DEMO版补过代码的人，请静默地飘远，永远有多远，你就飘多远。
