[Spoilers] 5422...

[Trueblue1878]

I see.. it must be out of only a few possible codes though because I have found from google/youtube that other people had 5422 as well. So I doubt the code is generated from 0001-9999

I wonder what the cryptic code on the computer means then? Cheers

It's the only way to progress. There's a differently generated code for each game.
