Unprotect for Where in Time is Carmen Sandiego.
This program checks for the original key disk each time you are
promoted in the game.
I found another unprotect on this BBS (CARMNTME.ZIP) which did
not work at all. If fact, it made it so you can not even get into
the program!
Here's mine. You can patch the file either with a hex editor, or
with debug.
Using a hex editor, such as those in PC-Tools or Norton's Utilities:
Search for the hex byte string: 02 E1 07 C3 FA 55
Change the first byte only: 12
------------
Using debug
>ren carmen.exe car
>debug car
-S0000 FFFF 02 E1 07 C3 FA 55 <cr>
xxxx:yyyy (note value of yyyy)
-e yyyy (type e, then value of yyyy above)
xxxx:yyyy 02.12 <cr>
-w <cr>
-q <cr>
>ren car carmen.exe
-------------
That's it. And a lot easier then the other patch that didn't work!
Although this patch only changes one byte, it was difficult to
come up with. They used a far call which was hard to follow, and
could not be nop'ed out. Good Luck.
