SDTool is a program for Windows to help you decrypt roms on your Nintendo Switch's SD card.
You need to have Windows, Python 2.7, pycrypto, and Java 1.8 installed. You will also need HacDiskMount.
Open SDTool.jar and follow the directions. If memloader asks for what to do, always tell it USB command mode. Remember to open HacDiskMount as Administrator.
