I did that too, but getting all 493 on pokemon diamond (only cheating for Arceus) is definitely my greatest achievement.
It only took me ~200 hours. Not that great of an achievement.
EDIT: several times, actually. I have the entire Pokédex filled (legitimately, never cheated) on Pokémon Pearl, Platinum and SoulSilver. I'm close to finishing White's Pokédex, too, but the last 3 Pokémon haven't been released yet. It'll probably take another 2-3 years before Nintendo decide to release Genesect, so I'm waiting patiently.
