I'm sure a large handful of people already know about this, but I thought it'd be a good idea to make this thread for those who don't commonly visit @dimok's GitHub. SEEPROM2SD does exactly what it sounds like. It dumps a copy of your SEEPROM to the root of your SD card in a file named "seeprom.bin". This application can be very useful for some people, as this BIN contains stuff such as your Wii U's drive key, devkit key, and your current USB key seed, as well as much more. Refer to http://wiiubrew.org/wiki/Hardware/SEEPROM for the full list. Sources: https://github.com/dimok789/seeprom2sd Usage: Run the seeprom2sd ELF using Homebrew Launcher. After a little bit, you should be back on the Wii U Menu. It is now safe to eject the SD card, and if everything worked correctly, a seeprom.bin will be waiting for you on the SD card. The file should be exactly 512 bytes. I've attached a ZIP below with a meta.xml and icon.png to go with application.
