when yuna was in the farplane in chapter 4, did you push x four times to hear tidus whistle? thats a necessity in getting the good ending.

im not sure but i also think you have to do it again at then end and hear him whistle again but im not sure so dont quote me on that one.

you also have to activate a lot of main events in the story to get the good ending.

i havent beat it yet because i want to beat the bevelle via infinito first...i have like 61 hours and 77% so far. i missed a lot so im going to have to use the new game plus to continue. but im pretty sure that with what ive done that id get the good ending.
