I know this isn't exactly the place for it, but I've been having some trouble with my 3ds and thought this might be a good thread to ask.
I've downloaded Picross e on my 3DS (I'm using an 8gb SD card I had lying around rather than the one that came with the system) and I am consistently getting the black screen "an error has occurred, please restart the system," normally after only a few minutes of play. When I go to the eShop and choose to 'repair software' for picross it recognises an error and says there's an 8 block download that needs repairing. One that process finishes I can play picross again (normally for around 40 minutes-1hr), but after a while I start getting the black screen again.
Has this happened to anyone else and is there a way to fix it? I've played virtual console games after receiving the error message with no problems, so it seems isolated to picross.
