Ultima Weapon anyone?

[Omega]

erm, since i trust the experience of those around me more then gamefaqs, and i think this might be helpfull for some.
ummm, in KH2 how do you get Ultima Weapon?
i was "questing" for it, but then i kinda forgot about it, and since i'm too lazy to go look and this place needs to be liven up, i think this might do the trick.

well I never had got Ultima Weapon on KH2 but this seems the way

Ultimate Recipe | Treasure (Twilight Town) | Can make Ultima Weapon

Got that item from that chest and go to a Synthesis store.
