This is for speedrunning purposes. Basically see this tweet for the rationale behind this. While the tweet relates to Super Mario Galaxy, the same technique works for the game Super Mario 3D World. As this relies on the eShop or piracy to write enough space to an external hard drive, when the Wii U eShop inevitably goes down piracy would be therefore the only option.
For this reason I'm looking for alternatives that don't require any official games to write to and fill up the external hard drive. Is there anything that could just write 0's or garbage to fill up a Wii U formatted external hard drive to be able to shave off the precious seconds?
