What Was the WonderSwan Development Codename?

The Bandai WonderSwan remains a fascinating chapter in handheld gaming history, known for its unique vertical orientation and the involvement of Game Boy creator Gunpei Yokoi. During its creation, the device was internally referred to by the development codename Project Atlantis. This article explores the origins of the WonderSwan, the significance of its codename, and the legacy of Yokoi’s final major hardware project following his departure from Nintendo.

After leaving Nintendo in 1996, Gunpei Yokoi established Koto Laboratory to continue his work in toy and game hardware development. Bandai partnered with Yokoi to create a competitor to the Game Boy, aiming to leverage his expertise in low-power, high-engagement handheld systems. The development phase was shrouded in some secrecy, leading to the use of internal codenames to protect the project from competitors before the official announcement.

The codename Project Atlantis was chosen to reflect the ambition behind the hardware. Just as the mythical city was seen as an advanced civilization, Yokoi intended the handheld to represent a new standard for portable gaming technology in Japan. The development team focused on creating a system that was affordable, had long battery life, and could be played comfortably in either horizontal or vertical positions, a feature that distinguished it from its rivals.

Released in 1999, the WonderSwan launched successfully in the Japanese market, securing a significant share against the Game Boy Color. Although it never saw an official release outside of Japan, the console is remembered for its strong library of Final Fantasy ports and unique titles. The story of Project Atlantis highlights the innovative spirit of Gunpei Yokoi and remains a key piece of trivia for collectors and historians studying the evolution of handheld consoles.
