Please Help.

My Wii U got soft corrupted (tried to install Wii U games using WUP Installer, and install failed due to my SD Card being bad.) I tried to delete the "unnecessary data" using the Wii U's system settings but took too long and shut off the console. What should i do?

wtf???

What SD Card should i use? My Onn SD Card is failing... Should I get SanDisk?

Why do people like making hard levels?

Modern Nintendo sucks... Past Nintendo rules!

My Wii U shut off while I was playing Super Mario Maker and the power LED started to blink red. Anyone knows what happened?

I thought this game was deep garbage...
