It is simple, use an Action Replay.
you need an action replay with walk/run anywhere on. all you have to do then is go through or around it.

It's the same one as the walk anywhere code you "walk" on water since you can walk anywhere
you must have an r4 and then download Pokemon pearl or diamond and press y on Pokemon pearl or diamond and turn on the walk hack my friends told me
Anywhere
Well, if you have an Action replay, you could use the go anywhere through anything: run anywhere, (running is quicker so don't do walk anywhere unless you take time) and this part is VERY, VERY, simple! Just walk forward inside victory road!
You cant
the cheat is walk anywhere or run anywhere
You just walk in there dumbo - _-'
On Pokemon pearl go to mt.cornet
To get Darkariin in Pokemon Pearl, first walk through the walls using codes. Then go to the island where Cresselia is. Walk through the passageway and Darkariin is there.
