Thank you very much for your great help. Unfortunatelly I had no time for looking further into this, because I have my final (school) exams in about one week :/

I was able to crack this in few minutes of fooling aorund (not having a clue to what i was doing).

I used PEiD on a program and it said it had Microsoft Visual Basic 5.0/6.0 [Overlay]. Im guessing the [Overlay] is the security and I need to use and unpacker to remove it (reaching here lol). Any advice?

PS: This is what part the alphabet would look like if Q and R were eliminated.

Thanks for all these wonderful tutorials and all your help, I understand how frustarting it is helping newbs.

Hi AustinX

The Overlay here is not packing so that will not be a problem. However Visual Basic programs are not that easy to follow and crack especially if you are just starting. I suggest that you find a target where PEID says "Microsoft Visual C++" or "Borland Delphi" - much easier to follow in Olly.

I have a few programs that i would like cracked that are "Borland C++ 1999 [Overlay]. I have also tryed using PE Explorer on UPX packed files, but I was only able to look at the source, and not run/debug them. Thanks for all your help and please let me know if you think the Borland C++ 1999 is too difficult.

Borland C++ is ok too.

BTW If it is the Heaventools PE Explorer you are using, you can open a UPX packed exe file then "save as" to a different name exe file. In most cases the saved file will be unpacked and run with no problems.

Thank you so much for your help. It is heaventools pe explorer, I was going straight to the disassembler instead of saving it and working with it in olly. I believe I have the hang of programs that you enter a name and serial. What I am having trouble with is the programs where they automatically generate a code that is one of a kind to your computer and then you have to enter in a serial matching to that code. I have tried serial fishing, but when I go to debug the prog in olly it crashes/freezes at the reg page. Jada^AoC has a few patches for programs mad eby the same site, I tried to make since of the coding but got no where. I have also been trying to find a good patch tutorial but everyone I have found is either to hard to follow or tells you what do rather than letting you try to help figure it out. Any suggestions would be greatly appreciated.

Did you try reading any of my tutorials?

Yea, The first tut was great, but it didnt work on these programs. The second one didnt match up with the program =/(silent update), and the third one went ^^^way over my head.

The thing I dont understand is that the site has many programs, 50+, but they are coded in many dif languages. They range from 7.0 C++, Borland C++, VB6 to UPX packed, but they all use relativley the same keycode/security/registration.

I was wondering since the borland C++ progs are very similair, ame design and layout, just different functions, if I could use one of the patches jada made and use a bytes adder and just rename the program to patch and add bytes till its the same file size as the patch needs, and maybe that would work. Otherwise, I'm stuck between a rock and a hard place.

UPDATE:I tried the bytes adder idea, would have possibly worked but the patch was still able to detect that it wasnt the right size, but I had the sizes and name matched perfectly.

I can't seem to get the hang of it because the registration code is one-of-a-kind to each computer. I believe I found the algo math within one the coding, but I am not sure/smart enough to figure it out.

Thanx for your tutorial SuperCracker i got the whole thing put in my head. I can serial phish and find the serial easy but when it comes to keygen and understanding the algorithm it gets abit harder. How do you understand the ASM language in olly. Is there a table or something to follow and translate into english?? Anywayz thanx for your help and great keygen Ziggy

It's just a habit ... When you crack every day you'll certainly understand what i say. Begining with patches is very important to understand jumps & calls and after that you can begin keygenning (in this case understanding each instruction is required).

This was my first time i was able to do something with no tut if you could only see the smile on my face when i fished the serial,Not really fished it but i found it in less then 2 mins.. now to learn keygening.....can you write anymore?

thanX

Well I cant write a keygen but I turned the program into one. Now it shows the correct serial instead of "Invalid Registration Information" in the alert. It also shows it down in the left hand corner where it says "Registered To:". So you just enter your name and a random serial and pop. there is the correct one.

This was a lot of fun to try. This is only my second success without a tut. :) Now to try and learn to write a seperate keygen. lol. Argh!
