Use a teensy 2.0++ for the extra IO's. You also need to remember that this NAND chip in the wii u has TWO 512 MB banks so both need to be dumped.
Dumping via the SD hack job is a rather shitty way to do it especially if you have a 32 GB console because it will take forever to dump it and you need to dump it AT LEAST twice and then compare the dumps to make sure there was no corruption in the data.
