Crack for Luminositi's SoftCam (
http://www.luminositi.com)
Tested with version 1.0.2, but probably will work with
some earlier and later versions.
Flying Raichu Super Happy Cat Power Club, 7/15/00
This one was a little tricky (just a little), because the code that we need to
patch is inside a dll (and there are a couple), and not the main program,
and because the .dll in question Scvideo.dll has no messages or text
that say the program has expired, etc.
The nag screen telling us how many days are left can be found inside
Softcam.exe, and that's naturally where we check first. However,
it becomes clear that the real check for expiration is handled elsewhere,
as the virtual camera driver can be invoked without starting the main
program and it still knows that it has expired (and blocks video).
So we assume it's in one of the dll files.
We use a method to find the culprit that has proven very successful for us
in the past:
1) find the registry keys program checks for registration or date
2) find the code that checks these registry keys
3) that's where the bitche's nest is, 9 times out of 10.
Purusal through the registry and monitoring with Regmon turns up some
interesting key in HKEY_LOCAL_MACHINE\Software\Luminositi\,
namely entires for registration number and user name.
Search the .dll files turns up a single piece of code which reads these.
(Win32dasm Search for SHELL.REGQUERYVALUE and "RegistrationKey")
We focus on the conditional jumps, and some brief exploration find that
we can make the number of days until expiration to 40,000.
That's okay, but we still have the nag and the logo superimposed on
captures.
BUT, taking a cue from the registry settings, we wonder if this program
checks the registry for a full license and is capable of running full
version. A little more experimentation shows that the answer is yes,
and does what we really want, makes the program fully regsitered.
We examine code and see a section processing the user name and
registration number, and in the middle is the code in question:
* Referenced by a (U)nconditional or (C)onditional Jump at Address:
|:0003.5458(C)
|
:0003.545D 837EEC00 cmp word ptr [bp-14],
0000
:0003.5461 7509 jne 546C
:0003.5463 837EEE00 cmp word ptr [bp-12],
0000
:0003.5467 7503 jne 546C
:0003.5469 E97200 jmp 54DE
NOPing from 0003.5461 to 0003:5467
kills initial nag screen
removes superimposition of nag logo
removes any time expiration
ie makes it fully registered.
--------------------------------------
We make a search and replace a patch with unique bytes, so that
the patch might work on earlier and newer versions of the prgram.
