The Nintendo Switch Online service has added seven NES games to the service, with one previously being a Japan-only title. These games are some of the last remaining titles from the NES' library that have yet to be added to the Nintendo Switch Online service. The seven games include Urban Champion, Golf, Cobra Triangle, Solar Jetman, Mach Rider, Donkey Kong Jr. Math, and The Mystery of Atlantis, which is also being brought to the West for the very first time through Nintendo Switch Online.

The Nintendo Switch Online's library of classic titles continues to expand through regular free updates. This service gives subscribers the chance to play a variety of classic games, some having the benefit of online multiplayer. While the library started with NES and SNES titles, the library has now expanded to include releases from the Game Boy, N64, Sega Genesis, and Game Boy Advance platforms. While Nintendo has mostly been focusing on filling out the Game Boy and Game Boy Advance libraries on NSO, there has been the occasional surprise update that adds older games.
