Yeah I actually deleted them but it still isnt working
Edit: Ah guys nvm, I reseted my internet settings, added it again and now it works. Still a bit weird, thanks anyways!
I dont know if its because of Pokegen, I created some legal pokemon and battled like 1 h and after a break I tried to connect again but I kept getting the Data Transfer error on random battles and its still occuring. But on my sisters ds it works ( she didnt use pokegen ) and we have the same settings and connection. Im just wondering whats going on
