There have been two non-profit Chrono fangames which received a substantial amount of coverage that were ultimately shutdown by Square Enix.

The first was Chrono Resurrection, a 3D remake of the original for PC, Xbox, Gamecube and the Nintendo 64. The second was Chrono Trigger: Crimson Echoes, a ROM hack of the original game which served as a sequel set five years after.

Both projects were stopped in 2004 and 2009 respectively, after receiving a cease and desist letter from Square Enix. An alpha version of Crimson Echoes has since been leaked online.
