http://www.wiibrew.org/wiki/RealWnD After comparing NAND dumps of YaWnD 0.3 and my DIY external NAND pargrammer, I've found a new good way to process error code -12 and -11. This is the RealWnD that can make dump 100% exactly the same as the dumps of external hardware programmers. Most NAND dumper fill buffer with zero for erro code -12. Although it works while restoring to NAND, it might potentially cause losing free space.
