Important Note: You should only see a few search and replace patterns added to the list and not too many until the dUP2 program hangs. You may see one or a few lines being added to search pattern and replace pattern.Ĭlick on the browse button to select the Target File that you want to patch.Ĭlick Save. Most of the time the original file will have an additional.bak extension at the end while the patched file will be the programs original file name.Ĭlick the Compare button once youve selected both the original and patched file.Ĭlick OK button to close the comparison done popup. Now youll need to select the original and patch file for the compare module to check for the location of the bytes that was changed by the patcher. Youll notice that Search and Replace Patch will appear in the Patch Script window.ĭouble click on it to open up a new Search and Replace Patch window. Right click on an empty space in dUP2, hover on Add and select Search and Replace Patch. It is advisable to tick the Run patch with administrator rights checkbox because most of the time youll need to run the patch from the Program Files directory and it will fail to patch if you do not run it as admin. Here is how to detect which bytes are being changed by the patcher and how to re-create a new patcher that could work for the latest version. The patcher reports wrong filesize or already patched It is possible that the software protection isnt updated to prevent the patcher from working, but the patcher did not work with the latest version because the program was recompiled, moving the location of the bytes that the patcher supposed to change and failing the CRC32 check.

Unfortunately it is nearly impossible to have someone to teach or coach you on how to crack programs other than learning it yourself from cracking tutorials that can be found in YouTube.īefore checking out the advanced cracking tutorials, we can show you a very basic and logical method on how to crack programs yourself based on an old patch that does not work with the latest version.įor example, an offset patcher for a program called ViceVersa Pro v2.5 build 251 2 released on 3 July 2013 by Nemo from team SnD will not work for the current version 2.5 build 251 3 (notice the difference in the build number). Only if you are able to think out of the box and figure out how to bypass the software protection yourself, then you consider yourself as a software cracker. Knowing how to crack a program using an available ready made patch, keygenerator or cracked files does not earn yourself the title software cracker.
