Eh, it wouldn't matter if you did it on the PS2 version, but since you no longer have one anyway, that's a moot point.

I also believe you can get 100% in X-2 in the first playthrough. I missed it myself by 1.2% or something, if I recall correctly. One thing I forgot was that darn Moogle @ the beginning.

Chocobo breeding was pretty fun. Good luck trying all of these!
