Silent Service Unprotect (TMH) 1. Copy the original Silent Service disk using DOS Diskcopy. 2. Load Debug.com from your DOS disk ( A>DEBUG ). 3. Place the Silent Service copy in drive A. 4. Use the following commands after you see the Debug prompt: a. -L 0 0 9 5 b. -E 91E 08 c. -W 0 0 9 5 e. -Q That's it! Boot up and enjoy! ************************* Also *********************** SOFTWARE PIRATES INC. presents Silent Service Unprotect This file will tell you how to unprotect "Silent Service" by Micro Prose. To complete this unprotection you will need the following: 1. A good copy program like BACKUP.EXE or COPYIIPC.EXE. 2. FIXSS.COM included in the package. BACKGROUND: The copy protection scheme used by Micro Prose on Silent Service is very good. I have found no commercial copy program that can make a usable backup copy of this disk. The Silent Service master disk has track 10 specially made. Track 10 has 16 sector ids on it instead of the normal 8 or 9. Using COPYIIPC, track 10 will be reproduced with only 10 ids on it. When Silent Service boots up it verifies that all 16 sector ids exists. The sectors on track 10 contain no usable data. Silent Service just makes sure that they exists. Knowing this we can go in and patch Silent Service so that it doesn't check track 10 at all. After patching the program we can go in and re-format track 10 to normal sector size. Finally, the makers on Silent Service, did one more little trick to prevent DISKCOPY from working. On track 12 side one, the sectors are in sequential order. This screws up DISKCOPY into thinking the disk drive door is open, when it is not. We must re-format the track to normal and put the data back. Also, just for kicks, we observed that there was no FAT table on this disk, but that the space where a FAT table would go was not used, so we put a FAT table out there. The will make the disk look like it really is a double-side 8 sectors/track disk to DOS. This allows DISKCOPY to know how the disk is formatted. With this done, you will have a working copy of Silent Service that can be copied by DISKCOPY.COM. Now I realize that most of you probably won't understand most of what I just said up there. That's OK. We provided a small program FIXSS.COM that does most of the work for you. Step 1: Make a backup copy of your master Silent Service disk. Your copy program must be able to handle non-DOS sector sizes. Norell BACKUP or Central Point COPYIIPC can do this. Remember to copy both sides of the disk, Silent Service is double-sided. Once you have copied the master disk put it away. You will not be needing it again. NOTE: The backup copy just made will not function ... yet. When you are done with Step 2, the disk will be DISKCOPYable. Step 2: Put copy of Silent Service into drive A. Then execute the FIXSS program. This program will make all the patches to the game for you. When it has completed you will have a DISKCOPYable version of the game.
