Introduction
|
||
------------
|
||
|
||
Ok guys, you now passed out of Kopy Klass 101 (dos files) and have this great
|
||
new game with overlays. How the phuck do I crack this bitch. You scanned the
|
||
entire .EXE file for the CD 13 and it's nowhere. Where can it be you ask
|
||
yourself.
|
||
In part II, I'll cover cracking Overlays and the use of locksmith in
|
||
cracking. If you haven't read part I, then I suggest you do so. The 2 files
|
||
go together.
|
||
|
||
|
||
Looking for Overlays
|
||
--------------------
|
||
So, you cant find CD 13 in the .EXE file, well, it can mean 4 things. 1, the
|
||
.EXE (though it is mostly .COM) file is just a loader for the main file. 2, the
|
||
.EXE file loads in an overlay. 3, the CD 13 is encrypted &/or hidden in the
|
||
.EXE file. 4,
|
||
your looking at the WRONG PHUCKEN PHILE.
|
||
I won't discuss case 1 (or at least no here) because so many UNP files are
|
||
devoted to PROLOCK and SOFTGUARD, if you can't figure it out with them, your
|
||
PHUCKEN stupid.
|
||
If you have case 3, use the technique in part I and restart from the beg. And
|
||
if you have case 4, shoot your self.
|
||
You know the program uses overlays but don't see and on disk? Try looking at
|
||
the disk with good old nortons. Any hidden files are probably the overlays.
|
||
These are the ones we are after. If you still can't find them, use PC-WATCH
|
||
(this program is a must!!! for all crackists. Traps ALL interrupts).
|
||
|
||
|
||
Using PC-Watch to Find Overlays
|
||
-------------------------------
|
||
Start up PC-Watch and EXCLUDE everything in the left col. Search the right
|
||
col. until you find DOS21 - OpnFile and select it. Now run the program to be
|
||
cracked. Play the game until the protection is checked. Examine you pcwatch
|
||
output to see what file was loaded right before it. This probably is the one
|
||
holding the check. If not, shit go through all the files.
|
||
|
||
|
||
You Have Found the Overlays
|
||
---------------------------
|
||
Great, now just crack the overlay as if it was a DOS file. You don't need to
|
||
worry about .EXE file, debug can write an overlay file. Part I explains the
|
||
basics of cracking. I suggest that you keep a backup copy of the overlay so if
|
||
you phuck up, and you will, you can recover quickly. Ah, and you thought
|
||
cracking with overlays was going to be hard.
|
||
|
||
|
||
Locksmith and Cracking
|
||
----------------------
|
||
The copy/disk utility program Locksmith by AlphaLogic is a great tool in
|
||
cracking. It's analyzing ability is great for determining what and where the
|
||
protection is.
|
||
I find it useful, before I even start cracking, to analyze the protected disk
|
||
to find and id it's protection. This helps in 2 ways. First, it helps you to
|
||
know what to do in order to fake out the protection. Second, it helps you to
|
||
find what the program is looking for.
|
||
I suggest that you get locksmith if you don't already have it. Check your
|
||
local pirate board for the program. I also suggest getting PC-Watch and Norton
|
||
Utilities 3.1. All of these program have many uses in the cracking world. |
