返回信息流从网上下载了一段程序，是基于VC6.0和DX8.1的贪吃蛇，里面包含有ddutil.h文件，安装了dx8.1，发现里面没这个文件，这个文件是哪个版本里的呢？
ps：只有下面一段源程序，既没有图片，也没有声音文件，能把它变成一个工程项目吗？

/*说明：ddutil.h 是 DX8SDK 里的文件。res.bmp 是包含了蛇、豆、墙的图像的位图文件，
back.bmp 是背景图片。gameover.bmp 是游戏结束的图片，pause.bmp 是游戏暂停的图片。
start.wav, die.wav, ate.wav 都是游戏中所使用的声音文件。
bass.h bass.lib 是 BASS 声音引擎的相关文件。
该工程需将 dxguid.lib winmm.lib ddraw.lib dinput8.lib bass.lib 加入 Link 选项中。
