"Ohneschanzenegger" - NUS Nand Builder
https://github.com/martravi/wiiqt
With this you can finally create a new Wii-NAND via NUS NANDBuilder, which will not cause any problems with NAND tools later!
A few years ago my friend nino reported to me about a problem with the NUS NANDBuilder for the Wii: With a newly created NAND, some tools (such as ShowMiiNAND) are not working - the unpacking fails. This happens even when the image is written on a Wii: any image created later by the NAND of that Wii will cause the same problem.
Together we went on the search - it was somewhere that the folder names were wrong. Ultimately, it was Nino who found out that the name was correctly resized to 12 bytes, but that these new bytes were not initialized. So here is garbage that has to be zeroed manually - and nino has now integrated this fix!
