1337-diff
|
||
|
|
=========
|
||
|
|
|
||
|
|
This tool accepts two input files and produces patch (diff) in `.1337`-file format. This format is compatible with patches produced by [x64dbg](https://x64dbg.com/) and applied by [Win\_1337\_Apply\_Patch tool](https://github.com/Deltafox79/Win_1337_Apply_Patch).
|
||
|
|
|
||
|
|
This tool is intended for internal usage to automate routine tasks related to windows patches. Implementation is really slow and prefers code transparency and correctness over speed.
