Hey all,
I barely used my Wii U at all since the Switch came out, it was basically unplugged for 6-7 years. But I got into homebrew recently, and I found out about the whole eMMC/MLC failing situation on Hynix chips. I checked with WiiUIdent and surely enough, my Wii U has Hynix chip, made in 2012/08.
I haven't had any games or apps give an error code or failing to load so far, but just to be sure, I made a new backup of my NAND to check for corruption. After extracting the contents of my MLC with the wfs-extract tool, this was the only error I got:
The title DB says 00050010-10040200 is the Wii U System Menu, so I got a little worried, but I was also surprised that this was the only error. Other people I've seen having issues with their Hynix eMMC had hundred and thousands of errors, indicating that their MLC has deteriorated far more than mine did despite mine being unpowered for far longer than theirs. Did I get lucky and happened to get a good 2012 Hynix chip that doesn't leak somehow? I've read that these types of small errors can be the fault of the NAND Dumper rather than the NAND itself or can be normal for one reason for another.
Should I be worried about this anyway, is it also a sign of my MLC deteriorating? Thank you for your assistance!
