Game Gear title Bishoujo Senshi Sailor Moon S has received a full English fan translation thanks to fan translators filler and Supper. The game came out back in 1995, and was exclusive to Japan.
While people are more familiar with a fighting game of the same name that released for Super Famicom, this game is a platformer with some minigames included. Sadly, you are only able to play as Sailor Moon in this game.
Check out some more screenshots below:
