Nintendo Power (Japanese: ニンテンドウパワー, Hepburn: Nintendō Pawā) was a video game distribution service for Super Famicom or Game Boy operated by Nintendo that ran exclusively in Japan from 1997 until February 2007.

However, Nintendo did see a market for an economical re-writable medium due to the popularity of the Disk System.

[2] The Game Boy Nintendo Power was originally planned to launch on November 1, 1999;[4] however, due to the 1999 Jiji earthquake disrupting production in Taiwan, it was delayed[5] until March 1, 2000.

[1][6] When this was on the market in the 1990s, the user would first purchase the RAM cartridge, then bring it to a store featuring a Nintendo Power kiosk.

In addition, each cartridge has a small amount of SRAM for saved games, which is divided into sixteen blocks.
