- Wordstar 2000 version 1.00 - Unprotect
- by Gerald Lee
-
- derived from
-
- dBase III version 1.10 - Unprotect
- by The Lone Victor
-
- The following instructions show you how to bypass the SoftGuard
- copy protection scheme used on WORDSTAR 2000 version 1.00. This is the
- same scheme used for FrameWork 1.10 and for dBase III version 1.10.
- Wordstar 2000 version 1.10 does not use a copy protection scheme, while
- versions 1.00 of dBase III and FrameWork used ProLock. To unprotect
- Prolock disks read the file PROLOCK.UNP.
-
- First, using your valid, original Wordstar 2000 diskettes, install
- it on fixed disk. Softguard hides two files in your root directory:
- CML0200.HCL and VDF0200.VDW. WS2000.EXE is the real Wordstar 2000
- program, encrypted. When you run Wordstar, the program WS2000.COM loads
- CML0200.HCL high in memory and runs it. CML decrypts itself and reads
- VDF0200.VDW. The VDF file contains some code and data from the fixed disk
- FAT at the time of installation. By comparing the information in the VDF
- file with the current FAT, CML can tell if the CML, VDF, and WORDSTAR.EXE
- files are in the same place on the disk where they were installed. If
- they have moved, say from a backup & restore, then WORDSTAR 2000 will
- not run.
-
- Second, un-hide the two files in the root directory. You can do
- this with the programs ALTER.COM or FM.COM, or UNHIDE.COM and HIDE.COM
- found on any BBS. PC-SWEEP2 is the easiest it will copy the files to
- another directory unhidden.
-
- Make copies of the two files, and of WS2000.COM and WS2000.EXE, into
- some other directory.
-
- Hide the two root files again if using ALTER or FM. Leave alone if
- using PC-SWEEP2.
-
- Following the WORDSTAR instructions, UNINSTAL WORDSTAR 2000. You
- can now put away your original WORDSTAR diskettes. We are done with them.
-
- Next we will make some patches to CML0200.HCL to allow us to trace
- through the code in DEBUG. These patches will keep it from killing our
- interrupt vectors.
-
- DEBUG CML0200.HCL
- E 3F9 <CR> 2A.4A <CR> ; change the 2A to 4A
- E 49D <CR> F6.16 <CR> ; if any of these numbers don't show up
- E 506 <CR> E9.09 <CR> ; it's not working.
- E A79 <CR> 00.20 <CR> ;
- E AE9 <CR> 00.20 <CR> ;
- E 73C 97 FA FA F4 F1 7E <CR> ; this is an encrypted call to 0:300
- W <CR> ; write out the new CML file
- Q <CR> ; quit debug
-
-
- Now copy your four saved files back into the root directory and
- hide the CML0200.HCL and VDF0200.VDW files using ALTER, FM or PC-SWEEP2.
-
- We can now run WS2000.COM using DEBUG, trace just up to the point
- where it has decrypted WORDSTAR.EXE, then write that file out.
-
- DEBUG WS2000.COM
- R <CR> ; write down the value of DS for use below.
- A 0:300 <CR> ; we must assemble some code here
- POP AX <CR>
- CS: <CR>
- MOV [320],AX <CR> ; save return address
- POP AX <CR>
- CS: <CR>
- MOV [322],AX <CR>
- PUSH ES <CR> ; set up stack the way we need it
- MOV AX,20 <CR>
- MOV ES,AX <CR>
- MOV AX,0 <CR>
- CS: <CR>
- JMP FAR PTR [320] <CR> ;jump to our return address
- <CR>
- G 406 <CR> ; now we can trace CML
- T <CR>
- G 177 <CR> ; this stuff just traces past some
- G 1E9 <CR> ; encryption routines.
- T <CR>
- G 54E <CR> ; wait while reading VDF & FAT
- G=559 569 <CR>
- G=571 857 <CR> ; WS2000.EXE has been decrypted
- rBX <CR> ; length WS2000.EXE = 1AC00 bytes
- :1 <CR> ; set BX to 1
- rCX <CR>
- :AC00 <CR> ; set CX to AC00.
- nWS12 <CR> ; name of file to write to
- W XXXX:100 <CR> ; where XXXX is the value of DS that
- ; you wrote down at the begining.
- Q <CR> ; quit debug
-
- Last, unhide and delete the two root files CML0200.HCL, VDF0200.VDW,
- and WS2000.COM and WS2000 directory. Rename WS12 to WS2000.COM and
- replace in the WS2000 directory. This is the routine that starts the
- real WS2000.EXE program without any SoftGuard code or encryption. It
- requires the .OVL and .MSG files to run. I have not tried it on a two
- disk systems but I think it should work.
-
- If you have any comments on this unprotect routine, please leave
- them
- on the Chino RBBS (714) 591-7002.
