shaymin/darkrai
This is an easy way to get shaymin and darkrai on Pokemon platinum
Get the walk everywhere code, activate it, go to full moon Island(where cresselia is) and walk towards Snowpoint city. Keep walking until you get to the island, don't walk up just sideways. Then battle darkrai to catch
Use walk anywhere code. Go to Pokemon league building, walk off the edge and take the cheater's way to the white stone. Hop on your bike, shift to high gear, and ride direcly up until you reach shaymin.
Note : this has the same effect as getting the members pass and oaks letter, but it is just one code if you are using codes. I have not tried but I do not think you can do both ways.( my way and using the actual event item.
