Released in Japan between 1999 and 2000 by Bandai, the WonderSwan and WonderSwan Color were innovative handheld consoles designed with input from legendary game designer Gunpei Yokoi. Known for their unique vertical and horizontal play styles, they delivered strong battery life and a library focused on RPGs and puzzle games.While never released outside Japan, WonderSwan hardware and games have become increasingly collectible due to limited availability, exclusive titles, and their connection to Nintendo history through Yokoi’s legacy.
