I own a Nintendo 3ds XL for a while and play pokemon xy on it. I wanted to swap via GTS pokemon, there was the screen of the Nintendo Black and it read "A connection error has occurred, press the POWER switch to end the game". I pressed the POWER switch and then restarted the game and tried again to swap pokemon, again the same. My Nintendo, however, is connected to the Internet, I have also made a connection test, this was positive. Can someone help me?
Then it lies on the opposite side. Not at you. I recommend Pokemon Ultra Sun, more players more Pokemon, of course this is not related to your question, but it's great fun!
More jerk but also. Actually, that's too much for the 3ds
That's right, that's why Nintendo also wandered the switch, so there are no more Pokémon games for the 3ds, etc.
