I did not see right?

You generate a random number then you compare this with the inputed serial:

004841D6    E8 79F0F7FF     CALL <RDG_Simp.System.Random> //Generate random number

004841DB    8D55 94         LEA EDX,DWORD PTR SS:[EBP-0x6C] 

004841DE    E8 9567F8FF     CALL <RDG_Simp._Unit3.IntToStr> //Integer to string conversion

004841E3    8B55 94         MOV EDX,DWORD PTR SS:[EBP-0x6C] //Load the result in EDX

004841E6    58              POP EAX //Put in stack inputed serial

004841E7    E8 7418F8FF     CALL <RDG_Simp.System.@UStrEqual> // Compare inputed serial with a random number

Ok bro

 

get the serial or patch the program..show me your best solution

[GIV]

I have deleted the program...

I saw somewhere the string "Congratulations" loaded.

Just change the loaded registers from wrong to right and that's it.

Even i copyed the the compared serial from the buffer where the good boy appeared when i have inputed in the box it shown wrong serial so i guess there is involved a random factor.
