The Wii U Virtual Console has received its first Nintendo DS title in Japan. Brain Age is now available in the region as a free download through the service. Originally released in 2006, the brain-training game presents quick mental activities that were designed to help players flex their mental muscles. It was inspired by the research of Dr. Ryuta Kawashima, a prominent Japanese neuroscientist. Nintendo has yet to release DS games on Wii U outside Japan.
