Nintendo Power was a service started in Japan by Nintendo in 1997 that allowed customers to purchase digital Super Famicom or Game Boy games from an in-store kiosk. Customers would buy separate blank RAM cartridges, put them into the kiosk, and select which games they would like to be written onto their cartridge, with a total of seven games being able to fit on each cart. The kiosks sold back catalog titles for a low price as well as games that were exclusive to the service for a higher price, although they were still cheaper than purchasing a comparable physical title at the time. The service was not that much different than Nintendo's Famicom Disk System kiosks from the 80s and, just like that Disk System service, customers would receive a small manual for every game they purchased at the Nintendo Power kiosk.
Nintendo Power remained in service long after new titles had stopped being developed for the Super Famicom/Game Boy and continued to sell games until the service ended on February 28, 2007.
