Today Super Mario Wii U succumed. The kids were just playing it yesterday. Today - Invalid disc
It now joins the trade-in pile with Super Mario World 3D, and Super Luigi.
Our other games by other vendors seem to work okay with exception of X-men lego which hangs up.
The fact is, there is nothing wrong with these games that we paid $60, but our system can't read them, and only has problems with Nintendo specific games.
Of course I've googled this and know ours isn't the first case. But given the evidence it sure seems that the problem isn't entirely with our system. It works for other games with no problems.
But when it comes to Mama Nintendo, we're currently a Marioless home. And that's a sad place to be!
Thanks!
