How do you get shiny mew in Pokemon Diamond and Pearl?

Answer 1

First, you got to have an action replay. Next, you got to have the modifier code. Then, you got to have the shiny code (note:this code will not last when you save. You're Pokemon will go back to normal.) Last, you got to have a Pokemon D/P game. Here's the trick to the modifier code: you will receive 493 master balls. You hold down the L button while tossing 342 master balls. Then, you run around in the grass while holding L, and a shiny mew will appear.
