Although it has never officially been released, the Dreamcast version was leaked onto the Internet, and was proven fully playable. The leak contains the full versions of Half-Life and Blue Shift , both with an early version of the High Definition Pack (it was from this port that the pack was spawned). Although, the leak has a somewhat inconsistent frame rate (though never to the point of unplayability) and lengthier load times when the player moves from area to area (around ten seconds, while today's average PC can load an area in around one and a half). In addition, there are some saving problems; the number of blocks required to save on a VMU increases rapidly as the player reaches the end of a level, then drops at the start of the next. While the game allows the player to remove files to increase space, sometimes it still isn't enough.
