                                from MicroForum

  This game was basically pretty easy to crack but had a few tricks up its
  sleeve for a rookie like myself.  Here's what I did to SHAKII.EXE:

  Step 1.  Removing the CD-Check.  This was basically pretty easy.  All I
           had to do was NOP out a CD 21 call.  No problemo.  Here's what
           I did :

           0B04:02CB    CD 21            =>         NOP
                                                    NOP

  Step 2.  Fooling the program to look for the files on the HD rather than
           on a CD-ROM drive.  The game stored some value in memory location
           EB+06 which it then decremented to determine the drive it would
           be looking for.  I had to patch Shakii so that it would only
           look on drive C, and then I had to force a jump to complete
           the crack:

           0B04:0451    MOV DL,[EB+06]
           0B04:0454    DEC DL,01        =>         MOV DL,02

           0CF9:0063    JZ 007B          =>         JMP 007B

  And presto, Shakii's cracked.  You might wonder why I bothered to do a
  crack.nfo, or why I included the uncracked EXE in a zipfile called
  "shakii-u.zip".  The reason is that I remember in the "old days" there
  were a number of crackers who did this so that other crackers and rookies
  might learn from the crack.  I don't know how much an experienced cracker
  can learn from the information that I've given you, but in any case, if
  there is a problem with my crack (I don't think there is), or if you want
  to see what I did, here it is..

  Many thanks go to Dark Overlord who helped me get started cracking stuff.
