CRACK ANY TYPE OF CD PROTECTION







How to crack any type of CD Protection, using W32Dasm (w32Dasm, and HIEW

Tutorial:-
First of all, you have to run the game you want to crack, without the CD. The game, doesn’t work of course, BUT a window pops up, telling you an error message. This error message will help you to crack the game so, you’ve got to remember it.

For example:
Please insert the - CD, or: You need the CD to play the - . ( -, is thegame you want to crack). Anyway, if you can’t remember it,write it, in a little piece of paper. Now, run Win32Dasm , and on the toolbar, press the first little button on the left, OR, go to Disassembler

->Open file to Disassemble.



  • A menu will pop up. 

    • Select the exe which you want to crack. 
    • The disassemble, will take few minutes so,OK, it finished its process. 
    • Now, in your screen, there is a strange text, and we can’t understand anything of course. 
    • Don’t worry, the only thing we have to do, ( If you want, you can change the font), is to click on the String Data References , the button next to the print button (Strn.REF). 
    • You can see a window which is called String Data Items . 
    • Scroll down, and try to find the game’s error message
    • . When you’ll find it , double click on it , and then,close the window, to go back to the Win32Dasm text.
    • As you can see you are somewhere in the CD check routine. This is the message’s place.
    • Now comes the interesting and difficult part, so, be careful.
    •  We don’t know what all this mean, BUT we must know the @ offset ofevery call and jump command. Write down , every call and jump @ offset number. (You have to be sure, that the OPBAR change its used color to green). You need the number behind the @offset without the h.

    Let’s go to Hiew.

    HIEW:



  • To move up and down, use the cursor keys.

    • Start HIEW. exe. In the HIEW directory, there is a list of exes and programs. 
    • Go to the directory, which you saved the game’s exe, we want to crack, and click on the exe. 
    • Click F4,and then, a menu will pop up, with 3 words. Text, Hex, and Decode. Click on Decode, and now, we can understand the list of numbers.
    • Click F5, and you can now enter the number, we wrote down, in Win32Dasm. Type it, and you will be placed at the number’s place. The cursor is placed on a command.
    • Before I’ll continue, I want to explain you something. For example, if the command where our cursor is placed, is E92BF9BF74, means that it is 5 bytes.Every 2 numbers, are one byte: E9-2B-F9-BF-74 = 90-90-90-90-90. 10 letters, mean, 5 bytes. The number 90, is the “Noop number”.OK, i hope you understood it ,
    • Press F3, which means edit, and now you can edit these ten numbers.Type five times, the number 90. For every byte, 90. Now click on F10 to exit.
