Few notes:
Although it's a Darkra/Shaymin glitch video all you need to just after you use surf is to go left or right and go up (around 100-200 steps I think) until you are in the Hall of Fame room.
Remember this glitch only works on the Early Japanese copies
Although I did get comments mainly from my Shaymin tweaking glitch video (the real one) that some people managed to trigger the Hall of Fame and completing the game.
One Youtuber has managed to take notes of the directions.

Here are the steps I took to get here:
Entered the Void:

1 Step South
5 Steps East
430 Steps North
Saved and Soft Reset
65,400 Steps West
64,840 Steps North to Newmoon Island
Then from there I just went all around fake-Sinnoh. And if I recall correctly, this happened at the northeastern edge of Route 215, right before Vilestone City.

I hope we can perfect this glitch. If anyone watching would like to try it, it should be pretty safe as long as you DONT save in fake-Sinnoh. However, if Cynthia saves for you, then you're good to go! ^^ Please comment on what you find if you do try this!
If someone used this as a TAS it would easily get rejected mainly because the glitch itself is nearly 2 hours in the void (and it's not entertaining at all).
I also looked this up on Google and it seems that they have a tutorial of the glitch on GameFAQ's.
