First you turn on the dsi with the action replay in it, then before it says this is a licensed product you hold down A+B+start+select at the same time the insert your game and look at the bottom left hand corner and it will say something like CPUE-38117 and you write that down. Finally you go to that star sign and click add new game, tipe in the name of the game click next tipe in the code and click next then you click b and it'll be there remember to press the 4 buttons after you turn on the DS do the 4 button part right away.remember this may take afew tries to get it right.I hope I helped
