Inspired by the initial reveal of the PocketSprite in 2016, the duo worked on creating a similar keychain-sized emulator system that would have a clamshell design. Resembling the larger Game Boy Advance SP just as the PocketSprite had resembled the Game Boy Color, the Keymu was first shown off in a video released in June 2017. Due to positive reception to their device from viewers and several media outlets, the FunKey Team decided to improve the Keymu to turn it into a commercially viable product. Following the creation of the FunKey Zero prototype, a keychain system that resembled the original Game Boy Advance, the team created the FunKey S, a slimmer and more powerful version of the original Keymu system.
