Wonderswan Color Crystal Compatible Operation confirmed in a Windows 10 environment. This cable alone allows for USB connection. This is not an official product, but a modified one. In modern environments, the official cable alone requires additional components. Recommended for those who only own Wonder Witch cartridges, for data backup with bootfriend. TransMagic for communication can be obtained from the official website. Playing JUDGMENT SILVERSWORD and Dicingknight, which won the grand prize in programming contests, is also good, but there are many limited software titles that can only be played on Wonder Witch, so please take advantage of this.
