It's been a couple of weeks since I last used my DSTWO, and now it just refuses to be recognized by any of my DS consoles. I've tried it in a DS, my DSi and my 3DS and it just won't show the icon. I've tried formatting my microSD card and starting fresh, but no success. I've even tried a second microSD card and it didn't make a difference. I've had the card since 2011, and haven't had any issues since then. Is my cart likely dead, or is there anything I can do to try and fix it? EDIT: The DSTWO still causes battery drain when inserted, so it is making contact with the slot.
