my wii u's sd card slot got broken. while i was trying to dismantle wii u, i broke its motherboard's corner.I went to my local video game technician, and he fixed the sd card slot easily, though he said he couldn't fix the motherboard issue. after 5 months of wait, he said he moved all of the components(he specified that he moved exactly 38 components) to a new motherboard, and he claims Wii U is working fine now. I don't think this is possible since the communication between components might be encrypted and such, and moving components doesn't feel like a something nintendo would allow.
