For anyone interested on how this happened, basically SciresM (the hacker) downloaded the latest Nintendo eShop database index and compared it to the older one, finding two new titles: Ever Oasis and Mario & Luigi DX.



So that's how we know the name and the title ID from this potential game. However, when querying the eShop server for more info on the specific ID there's nothing, as specific data hasn't been uploaded by Nintendo for any of the two games.
