My Wii u was running all fine last night and I did region hax on it and everything was good. Rebooted the Wii u probably 5 times and played some games on both rednand and sysnand. For some reason now today I booted it up and I get the error code 160-0103. There is a problem with the system memory. Don't really understand this because I haven't done anything to it and it worked fine last night? I have cbhc and rednand on my Wii u if this helps and I backed everything up, don't know if that matters though...
