How come people want this kind of save file? It ruins the fun of Pokemon... but to each their own. (Not a fight, just a curious question)
Took me 30 hours to complete the 150 pokemon pokedex for Sinnoh and now im halfway thru the National Pokedex in 40 hours.
If you cant find a complete save file, just make your own. It ain't that hard.
Also, when PKhex updates for DIamond/Pearl support, you can just use that and make your "complete" save.
Edit: Just saw that the games now have new update 1.1.1
Thankfully, I dont auto update.
