Hi, I cannot seem to be able to play local multiplayer between a EU 3DS, and a US 3DS+ Gateway, even though I run the EU rom on the US 3DS to be compatible with the EU 3DS. Every time I try, I get 'Connection Error'. here is my setup: 1 USA 3DS to play US games + Gateway 1 EU 3DS (latest version for online multiplayer) Due to some circumstances, I own two EU copies of Mario Tennis and Monster Hunter 3. Of course, they won't work on my US due to region lock, but I was hoping to use gateway in some way either to remove region lock, or run the EU rom on my US 3DS to play locally. I heard gateway was working for offline multiplayer yet it does not seem to work for me. Does it only work when both rom and 3DS are of the same region?
