I'm kinda stuck on this too. I was able to find what to do, and I've located all four of the hidden spheres. I can see all of the glyphs, and they appear to be 8777 the first of which being the Besaid village one and going in order to the Wakka/Tidus cliff one. The trouble is that I have a real hard time making out what the numbers are, and I've tried what I thik they are into the keypad in the cave, but obviously I must have something wrong as I always get "Nothing Happens". Are these numebrs static, as in can someone give em to me, or are they randomly generated for each game? If they are random, are there any tricks to seeing the glyphs? If only you could zoom in one more level it would be easy to see em.... grrrr....
