This is an xDelta patch to add a trainer to Chrono Trigger DS that adds the codes found here: 
(http://gbatemp.net/index.php?showtopic=84991&view=findpost&p=1563237)

This allows the flashcard to circumvent the copy protection in the game, 
allowing you to play without the constant lockups. 

Thanks to Narin, Normatt and the rest of the GBAtemp Cheat Crew for making the code. 
Enjoy!
