HOW TO UNPROTECT "KINDERCOMP" AND "KIDS ON KEYS" GAMES FROM SPINNAKER SOFTWARE (by Herb Sorock, 07/01/85) These "unprotects" will permit the backing-up of the "Kindercomp" and "Kids on Keys" games as well as permitting hard disk owners to run the games without the original disks in drive A. Some familiarity with the DEBUG program on the PC-DOS disk is assumed. KIDS ON KEYS ------------ 1. Take out the KIDS ON KEYS disk and make a copy of it on another disk using "COPY A:*.* B:" . Do not make the copy using DISKCOPY since the disk is protected. Put the original away in your "archives". 2. Put your DOS diskette in drive A and the KIDS ON KEYS copy in drive B. 3. Follow the "script" below. Lowercase is your input, uppercase is DEBUG's response. XXXX means the numbers in these spaces will vary depending on your machine's configuration. Note: if DEBUG shows something other than what is indicated below, you have a different version and this unprotect will not work. --------------------------------------------------------------------------- A>ren b:kok_ib_d.exe *.xxx A>debug b:kok_ib_d.xxx -u 12a9,12ac XXXX:12A9 CD13 INT 13 XXXX:12AB 07 POP ES XXXX:12AC 7302 JNB 12B0 -e 12a9 XXXX:12A9 CD.90 13.90 <-- hit space bar after first "90" -e 12ac XXXX:12AC 73.eb -u 0cff,0d05 XXXX:0CFF C70624007509 MOV WORD PTR [0024],0975 XXXX:0D05 8C0E2600 MOV [0026],CS -f 0cff,0d08 90 -a 0cff XXXX:0CFF call 0c75 XXXX:0D02 <-- just hit c/r here -a 0c75 XXXX:0C75 push ax XXXX:0C76 push ds XXXX:0C77 mov ax,0040 XXXX:0C7A mov ds,ax XXXX:0C7C mov byte ptr [0017],40 XXXX:0C81 pop ds XXXX:0C82 pop ax XXXX:0C83 ret XXXX:0C84 <-- just hit c/r here -w Writing 8500 bytes -q A>ren b:kok_ib_d.xxx *.exe ------------------------------------------------------------------------ 4. KIDS ON KEYS is now unprotected. Also, the program no longer refuses to acknowledge ctrl-alt-del so you don't have to turn off the power to run another program.
