A prototype of Chrono Trigger dated November 17, 1994, nearly four months before the game's release, was dumped around 1999.

This build seems to have been used as a demo: the game writes SRAM at bootup to produce three save files from different points in the story, both they and the New Game option have defined end points (followed by a plug for the game's upcoming release before resetting to the title screen), and NPCs block the exits or entrances of certain areas with text saying that you can't go beyond that point (a common tactic in demos to keep players from seeing more of the game than is intended).

Going outside the demo boundaries reveals that most of the rest of the game is present, though most of the events are (deliberately or otherwise) locked out and sealed off by a number of methods:

-The area is completely empty.
-Automatic blackout crash.
-The game resets.
-The game loads Crono's name entry screen and forces a New Game.
