Chosen Solution
I decided I wanted to head back in to Pokemon Y, but my 2DS won’t read it. It doesn’t show up. I have 2 separate 2DS’, and neither of them read the cartridge. They read other cartridges just fine, DS and 3ds alike. I’ve tried cleaning the cart pins and the handheld pins, nothing has worked. Any idea what’s wrong?
Jacob Macheca since other game cards are being read properly you know that this is not a problem with the device but an issue with the game card. Other than checking/cleaning the contacts etc. not much you can do the repair those. Of course you can try things like shown on here
