Tecmo Inc. recently sued the website administrators of a site dedicated to hacking into video games including some of Tecmo's games. Tecmo was particularly upset about modifications of the code to Dead or Alive Xtreme Beach Volleyball to make the players appear nude.
The lawsuit appears to have been effective, at least in the short term. The defendants' website is currently offline.
