Dragon Quest I – III will be the mobile versions 

Square Enix will publish both Dragon Quest and Dragon Quest II: Akuryou no Kamigami on the Japanese 3DS eShop this Thursday with Dragon Quest III: Soshite Densetsu e… scheduled for later this month. They are listed as Nintendo 3DS download software on the eShop and not Virtual Console as they are a port of the mobile version and neither the Famicom, Super Famicom nor Game Boy Color versions.
