Nintendo formulated a new way to distribute games in Japan with its Nintendo Power download service. Players could purchase a blank re-writable Nintendo Power cartridge for their Super Famicom and visit a nearby Lawson convenience store to access a kiosk featuring a full library of video game data. For a fee, these games could be downloaded to the Nintendo Power cartridge and then taken home to be played on the Super Famicom at one's leisure. Depending upon their size, multiple games could be loaded on the cart at one time; the player could then select which to play from a menu. Many games were first released for the Nintendo Power service and then eventually manufactured on individual cartridges. The reason for this is likely because the service was able to overcome the need for the time-consuming manufacturing and packaging process by instead providing games directly to the consumer. For this reason, games were also offered to users for a significantly lowered price compared to their fancy-packaged brothers. The service continued until 2000. Overall, several innovative games were released including the popular series of puzzle-games Picross NP and Yoshio Sakamoto's Famicom Detective Club. Nintendo closed the Nintendo Power service February 8, 2007.
