The following documents the procedure to unprotect the copy-protected
version of Sidekick ver. 1.11c.  All four sk programs calls a subroutine
to check for the modified track on the original.

The procedure is as follow:
* The user input is everything within the square bracket [].

1.  Copy debug.com & all sidekick programs onto a new disk.
    Put it in drive A.
2.  At DOS prompt, type [debug sk.com<enter>]
    A>debug sk.com
3.  Then after the debug prompt, type [u 07fd<enter>]
    -u 07fd
4.  Pls check the following carefully. If it does not match, you have a
    different version.
    XXXX:07FD BC0020    MOV    SP,2000
    XXXX:0800 0E        PUSH   CS
    XXXX:0801 E88686    CALL   8E8A
    XXXX:0804 2E        CS:
     .
     .
     .
5.  After the debug prompt, type [e 0801<enter>].
    Then type [90 <space> 90 <space> 90 <enter>]
    -e 0801
    XXXX:0801 E8.90 86.90 86.90
6.  Then type [w<enter> q<enter>]
    -w
    -q
7.  Now you can copy the sidekick program to your harddisk and forget
    about putting in the original disk in drive A every time you
    start Sidekick.
