Alright...I got Yuna's Nirvana and the moon crest and sigil....why isn't the weapon unlocked?

Also...are there any tips on how to defeat the Chocobo Trainer to get Tidus' weapon and get 0.00 to get his sigil???


THANKS!

1. When you get both the crest and sigil for any weapon, go into Macalania Woods and there should be a rainbow path on the left part near the intersection. Go up this path, and on the next screen take a left and there is this big flower/ball/thing that sits there. Press X and then it wil ask you if you want to upgrade a weapon or something like that. Choose the Yuna option and then it will ask you to show both the crest and the sigil. Once this is complete, then you will have unlocked the full potential of Nirvana.

Did you do all that yet?

2. I think that if you press and hold L1, R1, L2, and R2 at the same time, then you will have better control of the chocobo. It's all luck from thereon, but just try to lead the trainer into a bird or two to gain the lead.
