How do you get easy DP on yu-gi-oh championship 2008?

Go to wifi connection(must have local network) and then log on, go to the leader board and download a top players ghost data, unfortunately for the ghost data the computer is no where near as smart as a real person, and you can beat them with a decent deck, then you will get tons of DP due to the ghosts high ranking, players with above 10000 rank are most likey hackers, players with 65000 rank like are definitely hackers, don't download these.
