Oh thanks for the help.
I've got all the secret locations including the Omega Ruins.
So I need to learn bribe with Rikku (who I think sux compared to the others) and bribe those ppl you told me.
Ok no probs.
I have to actually go to the shop today where I bought the pirated version from and finish it there.
Coz my Ps2 is the older model and the lense is weaker
So i'll be finishing FFX in a shop. Not very atmospheric i guess.
