关于修改浴火银河2全高清硬盘版

我记得2013年的时候 写过一个修改欲火银河2HD的飞船数据的文章

飞船数据是ships.bin这几天心烦又偷偷玩了一下,又想改装备items.bin,然后时间少不想自己研究

于是看了下别人怎么改,确实有人改,但是写出来乱七八糟,也可能是自己的文档习惯不同吧

于是:

欲火银河2全高清硬盘版

Galaxy on Fire 2™ Full HD

不说那么多,二进制打开items.bin文件:

出于偷懒,我写了个程序查找0-1-2-3-...这样的偏移,以得到固定的存储空间,实际上不存在

稍微观察一下也不难发现,红色箭头所示,总是有0x00000000 0x00000000 0xXXXXXXXX 这样的三个DWORD

再看第一个红色箭头,值是0x1E000000,转换为x86字节序是0x0000001E,十进制的30,数一下选中部分的DWORD数量

正好也是30,再看绿色箭头不难看出,总是一个DWORD+一个DWORD这样一对一对的奸夫淫妇

而且,第一个DWORD为零时,第二个DWORD是0,1,2,3...这样递增的,像飞船的存储方式,可以认为是ID

那么暂定为非固定大小结构体:

typedef struct _tagValue{
	DWORD Flags;					// property flags
	DWORD Value;					// property value
} VALUE, *PVALUE;

typedef struct _tagEquipment{		// "items.bin"
	union {
		struct {
			DWORD Reserved1;		// 0x00000000
			DWORD Reserved2;		// 0x00000000
			DWORD NumOfDWORD;		// how many dwords followed
			VALUE Values[1];
		};
		DWORD Dummy[1];
	};
} EQUIP, *PEQUIP;

说到这里应该可以自己写程序编辑这些bin了吧

算了,贴上DLL部分的代码,也好做备份,有空的时候传到资源,大家有需要的就狠狠的下吧

(目前仅限修改飞船和物品)

这里用到了V32.dll基础类库,不过都是memcpy啊之类的自己用汇编写裸函数,同时封装为C++基类,还有一些SafeFree之类的宏定义和类型声明

就这样吧
