WonderSwan Color is a handheld console released only in Japan in 2000 by Bandai as a successor to WonderSwan. It launched with a price of ¥6,800 a little after the announcement of Nintendo's Game Boy Advance and unlike its predecessor it features a colorful screen. After a quite successful launch with 270,632 units sold in the first month and having a peak with 8% of the handheld market in Japan, the sales of the console declined when Game Boy Advance came to the stores in March of 2001, with a retail price of ¥9,800.
The casing colors of the console decided from a poll at Bandai's website, the same way as the original WonderSwan casing colors. WonderSwan Color has backwards compatibility with the WonderSwan console games. However, the game cartridges of the original WonderSwan console don't have a color, even when played in the WonderSwan Color.
