INSTRUCTIONS FOR UNPROTECTING VP-PLANNER VER 1.1 VP-PLANNER is one of those annoying programs which is both copy protected and delivered without a backup. Instead of forking out 10 bucks for the backup, I found it easier and more enjoyable to circumvent the copy protection. If you are comfortable copying disks and using DOS's DEBUG program then you should have no trouble with this simple procedure. This procedure was applied to a version of VP-PLANNER in which the VP.COM file was dated 4/14/86. If that is your version, then you are golden. STEP 1: Copy all of the working files from the VP-PLANNER master to a working diskette (or a subdirectory on your hard disk). STEP 2: Load the DOS DEBUG program and issue the following commands (do not enter the comments below. just enter everything shown in upper case.) COMMAND COMMENT _______ _______ a>DEBUG assumes A is default drive. -N B:VP.COM assumes VPP files on drive B. -L load vp.com into memory. -U CS:6647 xxxx:6647 mov bx,ffff this should be first . instruction displayed. . If not, STOP!!!! -A CS:6647 xxxx:6647 MOV BX,0 replace previous mov. - enter empty line. -U CS:6650 xxxx:6650 int 10 first instruction? . no? STOP! . -A CS:6650 xxxx:6650 NOP xxxx:6651 NOP xxxx:6652 don't forget the blank line -U CS:665C xxxx:665c int 10 first instruction? . no? STOP! . -A CS:665C xxxx:665c NOP xxxx:665d NOP xxxx:665e don't forget the blank line -W rewrite the file. -Q return to DOS. Believe it or not, VP-PLANNER is now fully unprotected.
