Beat FFIX recently. So my save-file is obviously on disc 4.

Just wondering, are you able to do the chocobo stuff on disc 4 with the world covered in mist? As I wanna get some ultimate weapons and Ark (beat hades already, just need that second pumice piece), and wanna beat Ozma too.

I have literally left all the chocobo stuff out. Not caught one or anything. Is it now too late?
