Software to create needed files for OpenDelta modified to get installed and used easily.
Before you can use the software the first time run ./install.sh
To create the needed files place your 2nd newest Rom file in the folder old and your newest in the folder new. Then run ./opendelta.sh. When the script finished it's work upload the contents of the folder publish.
This software, as also the app OpenDelta, has been created by Chainfire. I just modified it to make it easy to use for everyone.
