There is probably something wrong with the code like it was changed
they break the action replay so u can use it on diamond and pearl but if u put it on platinum it will break and wont work on anything....SO DONT USE ACTION REPLAY ON PLATINUM
An action replay DS does work on Pokemon Diamond & Pearl I use it all the TIME!
You have to buy an action replay.
Well it depends if you buy an action replay FOR ds, but if you buy one for dsi, it wont work
you probably need to udate your action replay for the code to work.
welll, it's pretty obvious: a diamond code is for diamond and a platinum code is for platinum. Like the other guy said, they wont work for each other if you try a diamond code with a platinum game its not going to work same way the other way around. you could have the same thing you wanted to get for platinum and diamond but the codes will be different. hope that helped. =)
Because the action replay makers have not made cheats for it or you haven't updated your action replay.
no
no
It wont work because you system software is or is over 6.30. The action replay people are trying to work out a way for it to work.
they give virusi's to your ds
All you have to do is click on the * button on the touch screen with your action replay in and hooked up. then scroll doen to Pokemon diamond/pearl and type in the code's name then type in the action replay code and then hit accept if the code is real, it will activate when you press the set buttons if not, it wont do anything. if it doesn't do anything then i suggest to delete the code if it doesn't work.
