Sierra On-Line, which makes King's Quest III and other great games, still has 
a copy protection mentality that needs defeating.  The accompanying procedure 
and programs will (hopefully) allow you to create a Backup version of King's 
Quest III from your Original disks that can be installed on and run from a 
hard disk without the key disk requirement.  You may also run KQ3 from the 
Backup floppy if you desire, the point being that you should play from
Backups and store your Original disks in a safe place.  

NOTE: This procedure works for Version 1.01 of KQ3 (Game Adventure Interpreter 
2.272) and is not likely to work with other versions.  You can check for the 
version number by pressing the Alt and D keys during play.  The Backup version 
has successfully run on an IBM AT, IBM Portable PC and Toshiba T1100+ Laptop 
(running from a 3-1/2" floppy).  

To create the Backup version, you will need:

     .  A PC running DOS 2.00 or greater and having at least one 360KB or 
        greater capacity diskette drive.
     .  The Original King's Quest III Disks 1,2 and 3 (Version 1.01).
     .  Blank diskettes (three 360KB or one 1.2MB diskette) on which the 
        Backup will be made, plus labels and write protect tabs.
     .  The programs, SIERRA.BAT, KQ3.BAT, DEFEATCP.COM, RUNKQ3.COM, CPC.COM,
        and _INSTALL.BAT, which accompany these instructions.
     .  These instructions.

Follow these simple steps:

     1. Format one of the blank diskettes.  If it is a 360KB (DS-DD) diskette, 
        format it with 9 sectors per track (both sides) and label it "King's 
        Quest III Disk 1 Backup".  If it is a 1.2MB (DS-HD) diskette, format 
        it with 17 sectors per track (both sides) and label it "King's Quest 
        III Backup".  (If you don't know how to format, read your DOS manual 
        or seek help from an experienced friend.) 

     2. Using the standard COPY command (not DISKCOPY), copy all the files 
        from your Original "King's Quest III Disk 1" to the Backup disk.  
        Don't worry about copying any hidden files from the Original.

     3. Using the standard DEL or ERASE command, delete from the Backup disk 
        the files _INSTALL.BAT and SIERRA.COM.

     4. Copy the six programs, SIERRA.BAT, KQ3.BAT, DEFEATCP.COM, RUNKQ3.COM, 
        CPC.COM, and _INSTALL.BAT, which accompany these instructions, onto 
        the Backup disk.  

     5. If your diskettes are the 360KB variety, use the standard DISKCOPY 
        command to make Backups of the Original King's Quest III Disks 2 and 3 
        onto the remaining 2 blanks and label them appropriately.  If you have 
        made the Backup on a 1.2MB floppy, copy to this Backup the files VOL.2 
        from Original KQ3 Disk 2 and VOL.3 from Original KQ3 Disk 3.  

     6. Put a write-protect label on the Backup diskette(s) and put the 
        Original King's Quest III diskettes away in a safe place!


You should now have a working non-copy protected Backup version of KQ3.  You 
may play this version either from floppies or a hard disk.  Simply follow 
Sierra's instructions that accompany the game, but use the Backup diskette(s) 
whenever the instructions call for a program disk and ignore the key disk 
requirement when running from a hard disk.

A FINAL NOTE:  Defeat of copy protection for KQ3 is accomplished primarily by 
the program DEFEATCP.COM, an 8K demon which installs itself in memory before 
KQ3 is called and monitors ROM BIOS INT 13 I/O requests by the game until it 
has fooled KQ3's key disk checks.  After that, it automatically unlinks itself 
from I/O and should not cause interfere with other programs after you quit 
playing KQ3.  However, space is still taken up in memory by the "dead demon" 
and 8K more will be used each time you rerun KQ3 until you reboot or turn off 
the computer.  For this reason, I recommend that you reboot your system after 
playing KQ3 to recover the space and avoid any problems.  

Good luck and please enjoy the game unfettered by key disk requirements.
