History of video games/Platforms/WonderSwan

Development
Following his 1996 departure from Nintendo, Gunpei Yokoi, the designer of the Game Boy and the Virtual Boy, spearheaded the creation of a new handheld with Bandai through his new company Koto Laboratory. Though Gunpei would die in a traffic accident in 1997 the console continued to be developed.

Launch
The original WonderSwan was released in Japan on March 4th, 1999 by Bandai at a cost of ¥6800 yen.

In 1999 an accessory was announced that would allow photos from a specific digital camera to be sent to a WonderSwan, however this device was not released.

In 2000 the WonderGate was announced, a device which would allow the WonderSwan to connect to NTT DoCoMo mobile phones and connect to the Internet.

The improved Wonderswan Color was released in December 2000, and managed to climb close to a 10% marketshare of Japanese gaming handhelds before the GameBoy Advance was released.

An ultimately unreleased GPS add on was demoed in 2001, as well as three games by Namco that would leverage the GPS support. Also in 2001 an unreleased wireless adapter for a Casio watch camera was announced.

The WonderSwan crystal was released in 2002 with an improved display.

Legacy
The WonderSwan Monochrome, Color, and Crystal collectively sold an estimated 3.5 million systems in Japan, the only region it was officially sold.

Compute
The WonderSwan uses a 16 bit SPGY-1001 processor, a custom version of the NEC V30 MZ, clocked at 3.072MHz.

The WonderSwan has 16 kilobytes of RAM.

Design
The layout of buttons on the system was designed to allow for either vertical or horizontal play.
