Quote:how do I use the script on the image file? Running swizzle_psvita_dreamcast.py through IDLE or the cmd line doesn't seem to do anything. Do I need to write my own script and import the un-swizzle file into it?
Yes, fastest and easiest way to do it is to write a custom script that handles all the operations you need.
To make it even more straight-forward you can use some IDE like PyCharm and set up a new project.
Please see some examples from readme file, especially "ReverseBox Demo" https://github.com/bartlomiejduda/Tools/...seBox_Demo
