Chosen Solution

I’m able to play Mario kart for a couple minutes but than it freezes. Of course I power it off and open it up again and the same problem happens again. I don’t think I need an update on the game since the eshop says I have everything updated

could be dirty cart slot use some canned air and blow it out if that doesn’t help with the console off, put some 99% rubbing alcohol on the gold pads of a game cart and insert and take out the cart a few times, leave to dry for 30 minutes, this will gently clean the contacts inside the console and on the game
