Tha cheatin' device sk8rboy mentioned is called Action Replay. You can get one at game store, dept. stores, etc. for about 20-30 bucks. I got mine at Wal-Mart. Just be sure to get tha cheat an' install it onto it since it don't come standard. They have ones fer that here on SC. I recommend either havin' a MasterBall or havin' lots of items an' strong pokemon before facin' Arceus. Also be sure to save yer game beforehand since as soon as you reach tha top of tha stairs there's no way out.
