To unprotect SimCity! Use Norton and change these bytes in the SIMCITY.EXE file: Change: 0c 87 00 75 3c To....: 0c 87 00 eb 3c ^^ You will need to use Norton's NU program. The address within Norton is: The File Offset 135,047 HEX 20F87 If the above doesn't work, try: The File Offset 134,850 HEX 20EC2 In Norton use the search for text and tab to the second selection for a HEX search.
