Bandai Wonderswan was introduced in 1999 as we have mentioned. This was the original model. A new version added color support and hardware improvements and it was known as Bandai Wonderswan Color. The last version was Swan Crystal and it was available on the market until 2003. In general, all of these versions were sold in over 3.5 million units, in Japan only. This was around 8% of the total market share in the entire country. The devices supported various games and some of them were developed by third-parties such as Taito and Namco. Bandai Wonderswan was eventually outrun by Nintendo Game Boy Advance which started dominating the market as the result of better hardware and more, available games.
