Wonder Stadium '99 Wonderswan ws SWJ-BAN019

Released just five months after the original Wonder Stadium, Wonder Stadium '99 doesn't add much in terms of gameplay. This update adds information about the 1999 Japanese baseball season, such as Matsuzaka of Seibu and Uehara of the Yomiuri Giants.

The game offers you a selection of 14 fictional and professional teams as well as three different stadiums, just like the original did.
