you need to get a device called "Action Replay DS". it is a cheat code system for the Nintendo ds and the Nintendo ds lite. here are some good websites or shops where you can order or buy them from:
Amazon.co.UK
Ebay.co.UK
or some local shops:
Argos(or order of the argos catologue)
The most commonly missed Pokemon in the National Dex are Arceus, Darkrai and Shaymin. These are legendaries in Diamond and Pearl that cannot be caught without action replay or a Nintendo event. Recently there were Nintendo events for all three.
Go to youtube and write "Pokemon Diamond and Pearl-HOW TO CATCH DARKRAI-WITHOUT ACTION REPLAY-TWEAKING GLITCH". It works! See for yourself.
You can, if you know how to, use tweaking and walk across the water to shaymin. Tweaking is most easy to do in jubilife city. can you describe this please?
