WonderSwan – WonderWitch

Console Name: WonderSwan
Release Date: July 18, 2000
Original Price: ¥11,800
Manufacturer: Bandai
Developer: Qute Corporation


The WonderWitch is a commercial development kit for the WonderSwan. Released by the Qute Corporation on July 18, 2000 at ¥11,800. The kit allowed any person able to develop software in the developing language C, to create software for the WonderSwan. It was supported throughout the  lifespan of the WonderSwan and was updated multiple time, including a major update on December 24, 2000 to add support for the WonderSwan Color and added support for Windows XP on October 29, 2001.

Extra cartridges were also available for WonderWitch which included the latest version of the Freya OS was also available for the price of ¥3,980.A separate debugging software called WATCHPOINT for WonderWitch was also developed by Sohpia Systems and sold for ¥4,500.

The WonderWitch was not for everybody as good programming skills were required to be able to use it. The development kit was also expensive considering that the consoles were sold to half the price of the WonderWitch. Even without being a huge success, the WonderWitch was able to gather a very active community of WonderSwan developers which gave the idea to Bandai and Qute to create a programming contest.


WWGP 2001

On November 9, 2000, Bandai and Qute launched the first WonderWitch context called the WWGP 2001 and offered a ¥500,000 grand prize. More than 148 entries were accepted. The vote was open to all members of the community and was held between February 21, 2000 and February 28, 2001 by  e-Mail.  On May 3rd, 2000, the contestants selected by the popular votes were invited to the Bandai Headquarters.


M-KAI won the 2001 edition of the contest with the game Judgement Silversword which  was eventually released as a full Wonderswan game on February 5, 2004 under the name Judgement Silversword : Rebirth Edition.
