I posted this to the list a year or two ago:
/* compile me: */
/* gcc -o region-zero region-zero.c */
/* set my perms: */
/* chmod 0755 region-zero */
/* move me to someplace useful: */
/* mv region-zero /usr/local/bin */
/* run me in directory VIDEO_TS */
#include <stdio.h>
main() {
FILE * fd;
fd = fopen("VIDEO_TS.IFO","r+");
fseek(fd,0x23,SEEK_SET); /* hex offset 0x23 is the region code byte */
putc(0x0,fd); /* zero all the region code bits */
}
The program I really want to see is the one that uses the
laser in a dvd burner to damage a commercial dvd in such
a way that it is deregionalized.
