Leaf used the XviD video codec in several games: Aruru to Asobo!!, Tears to Tiara, Kusari, and To Heart 2 XRATED. Since XviD is free software, released under the GPL, Leaf was forced to release the source code to those games under the same license. One still required the game data to actually play the games with the source code. A free software engine called xlvns was developed soon after Leaf released its first three visual novels.
