Nintendo Switch Online has just announced the addition of four new games to their Game Boy, SNES, and NES collections. Interestingly, three of the four games, namely Kirby's Star Stacker, Joy Mech Fight, and Downtown Nekketsu March Super-Awesome Field Day! haven't been available outside Japan up until now.

However, it's important to note that these games have not been translated and can only be played in Japanese. On the other hand, Quest for Camelot, the fourth game and the only one available in English, is an RPG originally created for Game Boy. It draws inspiration from a Warner Bros. movie with the same name.

To give you a brief idea about these games, Kirby's Star Stacker is a puzzle game for the SNES based on the renowned Nintendo character, Kirby. Meanwhile, Joy Mech Fight is a fighting game developed for the NES. Lastly, Downtown Nekketsu March Super-Awesome Field Day! holds the honor of being one of the first games in the River City series, which debuted on the NES in Japan.
