According to a recent tweet by Natsume inc. also known for the Harvest Moon Series. Nintendo maybe moving from digitizing the gray cartridges on the 3DS. This comes to a surprise to many of us as the virtual library was of classic games was one of the best parts about the 3DS and Wii U.
@MegaFlare0 Nintendo have moved on from Game Boy games. If it's a Natsume game not out now, it's not coming.
