Remember that if you patched a binary with bsdiff, the binary may not be executable after the patch. Which will apply the patch filename.bsdiff to filename. This can be done by moving filename.bsdiff to where filename is to be found (usually indicated in the patches section of every crack) and then issuing:īspatch filename filename filename.bsdiff Uudecode -o filename.bsdiff < Īt which point you will have obtained the filename.bsdiff file. This can be performed in a terminal by issuing: The best Windows alternative is Ascii Generator 2, which is both free and Open Source. In order to patch filename, you will first have to decode in order to obtain the filename.bsdiff. Monodraw is not available for Windows but there are some alternatives that runs on Windows with similar functionality. The uue extension indicating an universal encoded file (using uuencode), and: For example, the patch for filename would be pasted in a file called: Patches are named in this namespace conventionally and you will need to copy & paste the gibberish text in files before applying them. In case you have access and assuming you have Homebrew install, issue in a terminal: Most of the cracks presented here are for OSX and you will need either MacPorts or Homebrew to apply the patches. We can NOP the CMP as well, if we want to be tidy, but it is not needed.īsdiff can be used to create and apply binary patches. Xor cl, cl read (exchange) cmp rax, rbx compare nop no more jumping nop mov cl, 0x1 continue. īy substituting the jump using some NOPs (no operation): Xor cl, cl read (exchange) cmp rax, rbx compare jle 0x10001FF07 jump mov cl, 0x1 continue. The most obvious, given the top-down flow of execution, is to get rid of the jump ( jle): There are many ways to eliminate the jump in assembler. It does not matter whether reg holds the value 1 or not because the program will never return: Int reg = isRegistered ( ) // read if (reg != 1 ) Better illustrated, let's take the code from the flow-chart above: It does not store any personal data.Manipulating if-branches consists in negating either of the branches in order to favour in outcome. Of course, exporting as images is also supported (PNG and SVG). Because it's all just text, it can be easily embedded almost anywhere.
