So I haven't touched either cart in a few months. They both worked then. A week ago I try to boot it up, and my DSL won't load it past the loading screen of the cyclo itself (after the DS home menu, click on the button to boot the card in the system). Both my old white one and newer black one. Exact same thing. They won't fully boot up. On two different DSLs. All of the retail carts I've tried still work, so it's just both of my cyclos spontaneously dying at the same time... Anyone had anything like this happen to them? I even tried updating the firmware (even though it was the most updated, it still updates it if the update file is on the cart, obviously). So anyone have any ideas about what to do? I've already ordered a new cart, a supercard dstwo (wasn't out back then, and every swears by them so I'm gonna try it out). But if I could get these working again that'd be awesome.
