Have you tried your phone number?
I only know of five codes. (Stop here unless you're desperate!)
One is for the Xenon dome. You find it on the ship's display.
One is for Ortega. It is the top row in order plus one from the next.
One is for the Arcade. You find it in the ship when you pick it up.
One is for Estros. I think any random tries will find one.
