Clock G2 4.1

Type : Nice Clock program
Protection : Serial
Tech : Patching


Crack : I was unable to find a S/N for this program ....but ...this progy can
be easily cracked ......
Use APISpy ...we can see this program is looking for a registry key "Serial Number"
at 0x423CFA

So BPX 423CFA and see till our key is reached .... trace back ....

0x40FF94 CALL 41B980
0x40FF99 ADD ESP,04
0x40FF9C TEST EAX,EAX
0x40FF9E JNZ 410019
.............................

All we want to do is that CALL 41B980 should return EAX = 01 ....
Let us see what is inside ... this call ....

INSIDE CALL 41B980 ....

0x41B9B0 CALL 4011D0
0x41B9B5 ADD EAX,FF | 25 FF 00 00 00

Now BPX 4011D0 and continue ...we can see that this check is called again at

0x41A0E9 CALL 41B980

Patch :

0x41B9B5 OR EAX,01 | 0D 01 00 00 00
OFFSET = 1B9B5
