My Action replay ds codes won't work

Why doesn't Action Replay DS work?
i have a regular nintendo DS (which means not lite) and i could load the action replay code manager on my computer fine... but whenever i try using the codes on my DS it never works! When i try the infinite money code, and i play the game i still have the same amount! And this is the same with my harvest moon game. Please Help!

I have the exact same problem!
i got an action replay dsi, and all the codes are on it, but when i boot up the game with the codes, they dont work!!!!

so i got pokemon white. i put all the codes in manually on my dslite and when i select yes to start game with the codes it goes white and doesnt start the game or it stays frozen on the action replay screen...not sure why. i tried it afterwards with my soulsilver version and it worked fine and loaded the codes and started the game. any ideas how to maybe fix this would be great

Well mine does the same thing sometimes all you have to do is play with out it for a while(like a few days or a week) then try mine workswhen i do that. hope i helped

try updating it most of the time thats just the problem

You are going to need a DSi and a DSi action replay to get this to work. You will also need to upgrade the DSi's firmware. The default firmware won't work.
