How do you get to the n1 grand prix preliminary place on megaman battle network 3 white

Which round of preliminaries? For Round 1, go to ACDC Square: just follow the yellow brick road. For Round 2, go to Sci-Lab Square: again, just follow the yellow brick road. But for Round 3, this isn't even necessary: you show up in Yoka Square by virtue of simply getting on the cybermetro. Now ain't that somethin'. You may need a longsword E to advance at one point, from the Sci-Lab Square area.
