First of all, thanks to Cryo for explaining how void works. I was able to find a faster hall of fame path:
Current known fastest path to Hall of Fame:
10N (Getting to top left of the building, this steps varies depending on the building you tweak into).
An even faster path:
TWEAK MUST BE DONE IN POKETCH C.O!
You must also have saved the game prior to entering to the void.
You don't have to use Explorer Kit before this, the path will work anyway.
This one must be done in Poketch C.O. cause the path uses its map index.
