How to remove copy protection from
Impossible Mission II.


FROM:
THE COMPANY OF WOLVES
----------------------------------------------------------------
NEEDED:
Norton Utilities (or simular program).
A copy of the game file from your original Manhunter disk.
IM2_CGA.EXE if you have CGA graphics,IM2_TAN.EXE for Tandy,
IM2_EGA.EXE for EGA, or IM2_MGGA.EXE for MCGA.
A bit of your time.
----------------------------------------------------------------


1. HOW TO UNPROTECT IMPOSSIBLE MISSION II:
First load the appropiat file into Norton.
Search for the string A2 CA 99 A2 28 9C.
Change these 6 bytes and the next 6 bytes (total of 12) to 90's.
Write the changes.
Then search for the bytes CD 21 B9 01 14.
Change the CD 21 to 90 90.
Write the changes.
Now search for F6 C4 10.
Change the byte immediatly following the 10 (75) to EB.
Write the changes.
Next search for the bytes BB 09 9A 8B CD.
Change the 2 bytes before this string (72 xx (xx is different for
some of the above files)) to 90 90.
Write the changes.
Now search for B9 10 00 F3 A7.
Change the 2 bytes following this string (75 xx) to 90 90.
Write the changes.
Now search for B9 04 00 F3 A7.
Change the 2 bytes following this string (75 xx) to 90 90.
Write the changes.
Now search for B8 09 02 CD 13.
Change the CD 13 to 90 90, and the byte following it (73) to EB.
Write the changes.

Now the check for the copy protection (a bad sector on disk A) is
disabled. If you don't intend to use the game on your hard disk
you can now play the game from and DISKCOPYed disk. If you want
to play this game from a single directory on any fixed disk
follow the procedure below.

2. FIXING THE PROGRAM TO PLAY FROM 1 DIRECTORY:
Once again load the appropiat .EXE file into Norton.
Search for the string CHARS\.
Basicly you will type the file name after the CHARS\ over CHARS\.
For example if the full string is CHARS\THISFILE.A to
THISFILE.A(00) (Note. the end of the file name is denoted by a
00) hex). Be sure to look to see if the . after the file is
indeed a . or a 00 hex because some files have extentions and
some don't and make sure that you end the name you just typed
over ends with a 00.
Write the changes.
Repete the prodcedure until you reach the end of the file.
Next do the same thing exept look for the string ROOMS\.

Now when you copy the game just copy all of the files from all
directories from your original disks to the directory on the hard
drive you intend to use. You can now enjoy the game without
flipping thru floppy disks.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
