I saw this on another forum: Q. Is there any way or even better a program that can convert codebreaker ds codes to action replay ds and vice versa? A. There's a program for it, actually. It's called NDSconvert. http://doc.kodewerx.net/tools.html#nds It has problems with any codes that use the Action Replay's dx data register codetypes, but for simple codes (Not pointer codes, etc) it works well. Also note that since the Codebreaker code encryption isn't broken, encrypted Codebreaker codes cannot be converted.
