I received a sky3ds Friday, loaded a few files onto it, and it worked great. This morning I tried it again: the light no longer illuminates when I press the button, and the 3DS indicates that no cartridge is in the slot. I've already sent a question to the vendor about replacement, but if they won't replace it am I SOL? Is there anything I might be able to try to jumpstart this bastard back to life, or at least verify for sure whether it's dead? I've already verified the SD card is fine and formatted properly.
