Pete, voici l´énigme de la méga materia 4:
You get one chance to enter the passcode correctly, then after that you have 3 minutes in which to frantically punch in buttons while Cid tries to help. Let´s see if you can figure it out for yourself, if you don´t plan on doing this the hard and nerve-wracking way. If you can´t, the answer is below.
His hints are ( abbreviated for easier reading):
The first digit is not a Square.
The second digit is not a Triangle.
The third digit is an X.
The last digit is either a Triangle or an X
One of the buttons must be pressed twice.
Another hint, " Did you use the Triangle? I´m pretty sure you didn´t" is misleading, probably due to a translation error.
It makes you think that you might need to use it. In fact, you don´t. It´s not in the code.
Still can´t figure it out? The answer is below, but don´t look unless you absolutely give up...
Code 1 : -O-
Code 2 : -Carre-
Code 3 : -X-
Code 4 : -X-
