Nope. But friend of mine will try to do something with this using NDS Adaptor Plus. I bought the game on ebay so there's no way that i can return it. Also there's no Nintendo consumer support in Poland http://microsite.nintendo-europe.com/poland-europe/ So they can't help me either
I've got a problem with Mario Tennis Open 3DS.
I was playing the game in online mode few weeks ago. Everything was ok until the battery died during saving.
Since then my 3DS has been showing me the message mentioned in the tittle.
I post a video below to make it a little bit clearer...
