the timer from ending
- If you have already cracked it you could
patch through all three stages (OPTIONAL)
Difficulty: Hard Medium

For killing the timer, just change this
| Code: | | 00404E30 55 PUSH EBP |
to RET.
I quickly checked up the three stages and they could be easily bypassed by changing the je to not jump(NOPing) or jne so you can enter fake pass.
| Code: | 00404C25 /0F84 78010000 JE 00404DA3
0040539F . /0F84 36010000 JE 004054DB
00405CAC /0F84 45010000 JE 00405DF7

I will spend some more time on it and find the right passwords. Its fun indeed hehee

Is this even possible..? 
You do know that 0 & 1 = 0...
The problem is that you compare each password twice, and each time you do something diffrent with the result, which results in performing Bitwise AND on -1 or 1 on 0.

[img]boon.no.lv/tmp/somethingwrong.png[/img] (I understand this board gets it's fair share of spammers ,but this is ridiculous.)
Hmm , I think I'm doing something wrong  .
Coul anyone explain , what exactly am I doing wrong , if I "help it make the right choice" permanently , it displays an error:
"Run-time error '401':
Can't show non-modal form when modal form is displayed".
