I have come to the part where you have to get that code from the tomb of the unnamed king to get into the mansion. I even got a walktrough for this problem. It says that the code changes for every game. So I cant just find it from web. When I found a sword near the entrance of the tomb it only says "Student Identity Nr.1". I read that here the code should be written. I shearched the whole tomb and won easy against the brothers, but the code is what I need! Is this a bug maybe?
By the way, I have the version for the PC only.
Can anyone help? If not, can someone give me a save right after the code?

All you have to do is look at the kid's identity. If it's 1, then it's 1. Fighting the brothers is purely optional.

But what should I do with the identity? The code is made of three numbers, and putting in 111 does nothing.

001...

You might be looking at the wrong thing. iirc the Student ID should be on the floor as soon as you enter, in the shape of a sword. It's literally 3 steps in, so idk why you'd fight brothers unless you want them. but if that's what it said on the sword, that is the number so yes you would have to type "001".

I accept it, I am dumb. Yes it is "001". I did not think that way. I did not see the tree from the forest... Thanks anyway to both of you! Now I can finally continue final fantasy :)
