续上文:
破解了IC卡读写器的动态库,实在让人心力交瘁,蛋疼之下,随便找了个游戏玩玩
一不小心,玩上浴火银河2硬盘版(Galaxy On Fire),这个游戏有很多个不同平台的版本
感觉移动好吃力,跑半天都不到目的地,我们这样的人怎么能忍受龟速?更不用说是蜗牛了!
于是抄家伙,疯狂破解!(- -!这家伙,破解上瘾了……)
最先破解的是后燃器的加速时间、冷却时间和加速倍率,我改过最高的如下:
加速时间1分钟,冷却1秒,加速1000倍!
主要是我想撞一个行星看看是什么样的效果,结果我飞了半天硬是没撞上!
而且,加速太快,摄像机跟不上,直接往后面看了……
因此,这一块就不跟大家共享了,只贴一张图证实真相:
一次加速就飞了4000多公里,星球还是望尘莫及,于是回头截个图……
破解出来比较实用的是修改飞船仓库容量和装甲等,先上个图:
我不想破解别人的东西,我只想传播下技术。
某人说,某人有些虚荣心,喜欢做些惊世骇俗的小动作,不为建功立业……
下面是动态库各个文件的C/C++源代码(按文件名顺序),编译为DLL即可调用(太累了,主程序不想写了,源码也在有空再上传了)。

Hash.cpp和Hash.h是计算MD5的,可以计算任意内存块的md5,目的是检测玩家是否修改了文件
以确定要修改,还是先做备份……主程序都没写,这个也不发上来了,而且容易泄露大侠我的加密风格……

目前只公布修改飞船的代码,看看大家反应如何先,如果都有需要,那我就为人民服务一下下吧%……
