Sometimes my sky3ds+ doesn't work. I don't know why this happening. I had this problem 2 times, first one is Animal Crossing save file doesn't wanted to load, Preparing your town...and that's it. No blue light. I had to reboot my device. Second time is when i was switching game list through the buttons, carefully, slowly, and it stops to work, games has stoped to switch like i have no cardridge inside. And what is more interesting is that i always get this file (screenshot) while my sky3ds stops to work.
