I haven't used my 3DS is a very long time, so when I turned it on to find an enormous black thing on the top screen, I was scared. I haven't touched it in at least a month the, so I have no idea how this happened. I would take in into GameStop for possible repairs, but I just spent my money on a Dead Space game literally yesterday.
Is there anything I could do at home to possibly fix this, or will I just Have to wait a couple months until I get more money?
