Heboris

Heboris is a game developed in 2001 by Kenji Hosimoto, aka Hosiken. Many, but not all, of its behaviors bear a resemblance to Tetris The Absolute The Grand Master 2 PLUS, the latest TGM series game at that point. The game was developed using YaneuraoGameScript 2000 (YGS2K,) a scripting language and runtime environment created by Urao Yane.

Development of Heboris by Hosimoto has pretty much been in stasis since 2002. However, due to the nature of YGS2K in that it is a script language and the source code cannot be made truly inaccessible, it became the target of modifications by anonymous third parties mainly in the 2ch community. The game underwent various modifications, including implementing similar features from games such as Tetris The Grand Master 3, Tetris The Grand Master Ace, Tetris DS and DTET. The modified version is known in western communities as Heboris Unofficial Expansion, or Heboris U.E. as short. A second modified version, Heboris U.E. LITE, exists and focuses on lighter system requirements. A third modified version, Heboris U.E. MINI, also exists and features a plugin system to add or remove functionality from the game.
