U.S. tourist David Madrigal is over the moon after paying $200 for a "vintage" console at a busy Tokyo store that is tapping into booming global demand for retro gaming kit.

"When I came into this store, I was like a kid walking into a candy shop," Madrigal, 23, said at Super Potato in the Akihabara district, famous for its pop culture shops.

"This stuff is my passion. I love older consoles," he said. The PS Vita, a console released in 2011, that he bought "would usually cost me about $600 in the U.S."
