IDA Patcher for Windows

December 20, 2011 - Posted in Other , Programming Posted by:

Not too long ago I found myself needing to patch a .dll with a .dif file produced from IDA, after a very quick and admittedly quite lazy google turned up nothing I decided I needed to just write a quick one. I figured I would share with you the result.

It’s quite simple, select the target file you wish to patch and select a .dif file with the patches you wish to make. Note: the .dif files produced by IDA need to either have their first 4 lines removed or simply add a ; to the lines with text (turning them into what my patcher sees as a comment and ignores) otherwise it expects a format of:

Example Dif File

As you can see above this .dif file would make 8 bytes changes within the specified target file.
