My friend just bought an used 3DS with Gateway, but he cannot run the custom Fire Emblem Fates rom I have which I acquired from xxxx. When he launches the game the game apparently just loads infinitely and nothing ever happens. It works just fine on my 3DS and I sent him literally the file I'm using from my 3DS. Neither of us really know anything about modding or Gateway so I can't really tell him what's wrong :c. I bought my New 3DS used as well with Gateway installed. Would it be safe to assume he needs to update his Gateway? Both of us want to update our Gateway regardless for Pokemon Sun/Moon, but like I said before I don't know anything about modding and I don't want to brick my console .. :c.
