Hacking Cheat code questions

[Riversong]

So I'm using the AK2i cheats for Pokémon Platinum when I notice something: under encounter codes, it says to input the nature code/number into the calculator app and press select. The trouble is the nature codes/numbers aren't given. Any suggestions as to where to find those codes/numbers?

You're best off just simply googling them. But this reply would be pointless if I didn't do it for you, wouldn't it?

That link should work. If not I'd just try getting another code database that is more customizable, which trust me, is really hard to find.
