I picked up a used Wii U for free from a car boot sale as the guy just wanted to get rid of it. Took it home, fired it up and it wouldn’t boot. Just a black screen with a “-3” in the top left corner. I can see why he gave it to me for nothing ( but the controller is perfect ). Is this the type of Wii U with a “-3” that can be salvaged or should I just throw it in the bun? I’m pleased I got a second co troller for free and all the cables
