- Almost Unprotecting Leisure Suit Larry II
- ***************************************************************************
-
- Leisure Suit Larry II is arguably Sierra Online's best interactive graphic
- adventure game. It is protected by the singularly obnoxious "answer a ques-
- tion from the manual" trick. When you start the game, you must fill in the
- last four digits of a girl's telephone number. The pictures of these girls
- appear throughout the manual.
-
- This unprotect requires changing four bytes in the file SIERRA.EXE, found
- on diskette #1. However, this unprotect is not as perfect as I'd like it to
- be. I set out to make the unprotect completely bypass the "Type in Phone
- Number" screen. Well, as I traced the code I found that to do so would
- be considerably difficult and would require the modification of extensive
- amounts of code.
-
- Instead, the modification we will make will cause the same girl's picture
- to appear every time you start the program. This means that you will be
- able to enter the same phone number every time you start the program. The
- phone number will be 7448.
-
- Nothing herein is to be construed as subversion of or violation of the rights
- of the authors of these "copy protected" games and other items. These authors
- certainly maintain the right to protect their works in any manner which they
- deem fit. However, their decision to inflict difficulties in the operation of
- their products by legitimate users should be protested vigorously. This docu-
- ment is a living example of my heartfelt belief in this matter.
-
- This unprotect requires a file utility such as PC-TOOLS DELUXE or NORTON's.
-
- Search for the following four-byte hex string:
-
- 8B C2 EB F4
-
- And replace it with this four-byte hex string:
-
- B8 02 00 90
-
- Write the changes and your done. The phone number will always be 7448!
-
- For people familiar with debug, the location of these bytes is 8BBD through
- 8BC0.
