MpegTV Player一分鐘聲音限制破解法!!

#include <stdio.h>

int main(void)
{
        FILE *f1,*f2;
        int a[6]={0,0,0,0,0,0},i,k;

        f1=fopen ("mtv","rb");
        f2=fopen ("mtv.new","wb");

        k=0;

        while (!feof(f1))
        {
                k++;
                if (k>6)
                {
                        fputc(a[0],f2);
                }
                for (i=0 ; i<=4 ; i++)
                {
                        a[i]=a[i+1];
                }                      
                a[5]=fgetc(f1);

                if (a[0]==106 && a[1]==1 && a[2]==106 && a[3]==0 && a[4]==106\
                    && a[5]==21)
                {
                        printf ("\nFound!!\n");
                        a[1]=0;
                }
        }
        fputc(a[1],f2);
        fputc(a[2],f2);
        fputc(a[3],f2);
        fputc(a[4],f2);
        fputc(a[5],f2);
        fclose(f1);
        fclose(f2);

        return 0;
}

Process:

1.將上列編譯成可執行檔.

2.將可執行檔和mtv放在一起run後會產生mtv.new

3.執行mtv.new後,即可破解一分鐘聲音的限制.

PS.(a.It have tried in mtv-1.0.7.2 and it can work.

   (b.這不是註冊機,只是純脆在1分鐘後disable mute.

   (c.感謝 PaulLiu提供此方法.

      And when the stars are shining brightly in the velvet sky,
      I'll make a wish send it to heaven then make you want to cry..
      The tears of joy for all the pleasure and the certainty.
      That we're surrounded by the comfort and protection of..
      The highest power. In lonely hours. The tears devour you..
