I have been wondering this for quite some time.The puzzle was rather hard indeed.I honestly had to use a strategy guide for this one, how about you guys?
Also I was wondering how many of you figured out the Huge Materia Rocket code on your own...I did this one by writing down every possible combination of the four buttons, and luckily I started with the right button, and got it quickly,but had a lot of pages of writing I didnt even need lol.
