Seeing that some of you have trouble decrypting roms, I've created a very crappy coded Python script that does most of the command line work for you.
Instructions:

• Download this script: http://pastebin.com/raw.php?i=PNAm1sud
• Run it (python myscript.py)
• Follow the instructions

You need ctrKeyGen, ctrtool and padxorer in the folder where the script is.

Hi, I've refactored/improved the tool. Now it shows a percentage and it's a little bit faster.
