[软件]：飘雪动画秀3.02
[软件简介]：用于制作GIF动画的，还可以优化你现有的GIF图片，可输出GIF图片并且可以支持
输出AVI。做头像logo特别好。
[下载]：《软件王》2002.12期上面的，不知道哪里有下载。
[保护方式]：用户名，注册码
[破解工具]：trw2000

要注册，也不知道网上有没有，搞定它先!!
加过壳的，姑且不理它，用trw2000下bpx hmemcpy，pmodule很容易就到了这里。

终于搞定了，顺便贴个c语言的注册机

//keygen for 飘雪动画秀3.0.2
#include "stdio.h"
main()
{
unsigned char a[16];
int d,i,bbbb;
int eesi=3039;
printf("This keygen is made by Bartchen\nPlease input your name : ");
gets(a);
d=strlen(a);
printf("Your Register code is : ");
for(i=0;i{
bbbb=a[i];
eesi=eesi+bbbb*(i+1);
if(eesi>6078)
{eesi=eesi-6078;}
}

printf("mg37xxx");
printf("%ld",eesi);
printf("\nPress Enter key to exit");
gets(a);
}

唉，天快亮了!不睡觉了，直接看“魔电”吧，要不然就挂了。

Bartchen (for everyone)
