Pokémon Diamond and Pearl Surf glitch/Darkrai Path

The Pokémon games by Game Freak have been known for their solid gameplay as well as a healthy dosage of secrets. Aside from the standard batch of creatures that roam the regions that you travel in, there are always a special few Pokémon that you have the one rare opportunity to challenge and either defeat or attempt to capture. In Pokémon Diamond and Pearl, not only is this still the case, but to an even greater degree. You have a lot more of the rare kind this time around, and you're still given that one measly Master Ball. It's simply something all players of Pokémon games will have to deal with once again.

Newmoon Island
To access Darkrai, from where you should now be standing, and using the Poketch's built-in Step Counter, walk 146 steps to the east. After that, walk 254 steps south, for a total of 400 steps.

If you feel you've messed up, you can either attempt to fly from where you are to the game's other areas or retrace your steps if that does not work. The next part is what can mess some people up very easily, as you will have to be unusually still for a certain amount of time.

Now, use the Explorer Kit to go underground. This will cause you to save. When you go underground, DON'T MOVE! Simply resurface. Guess where you are? You're at Newmoon Island! The place looks a little messed up, but don't worry about that. Maneuver yourself west around the glitchy visuals for a short distance, or look at your Map Key Item to help clear it up, then afterwards travel north into the woods. Floating right before you is the rare Pokémon Darkrai!
