ive just got all the master materia from defating the emerald weapom on disc 3, but i want to know is it to late for me to get the Neo bahamut materia where is the whirlwind maze?
thanx to anyone who helps

It is too late, as far as I know. That's the only time you can pick it up. Sorry, but it looks like you've gotta head back to disk 2 and get it again. :(
