This procedure will enable you to unprotect Sierra On-Line's
THEXDER game. The procedure is based on an unprotect
procedure for KING'S QUEST III, by an unknown author.
There are two files included in this ARC package:
1. THEXDER.DOC - This file
2. THEXDER.DAT - Supplementary file needed during DEBUG
session.
The procedure is relatively simple:
1) Put a blank, formatted diskette in drive B, and the THEXDER Disk
#1 in drive A, then at the A> prompt, COPY *.* B:. Then put Disk #1
away - you won't need it anymore!
2) Load DEBUG, making sure both THEXDER.COM (on the backup disk) and
THEXDER.DAT (from this package) are both in the current path or on
the default drive.
3) Use DEBUG to patch THEXDER.COM.
-N THEXDER.COM
-L
-R (Record value of CX register - [0B4C] )
-N THEXDER.DAT
-L 141
-E 34F
XXXX:034F E8.90 [space bar]
XXXX:0350 B2.90 03.90
-N THEXDER.COM
-R CX
CX 0080
:???? (Enter value of CX you recorded - [0B4C] )
-W
-Q
4) That's all there is to it. THEXDER is now unprotected.
