The first few games I had on the cart worked without a problem. Now I've ran into a problem where if I add a new game and have it show up as my active game, it changes to the next one automatically. If I hold the blue button before the game changes it won't change and I can play it just fine, but the blue light keeps blinking and it will not save. I've tried multiple SD cards and it did not solve the problem. If I re-add any of the games that worked before they will still work, it's only new games that are having problems. Has anyone had this issue before or is my card just defective?
