Is there anything in any Pokemon game where something changes per each save file?

Question

Like its unique per save file. E. G. in majora's mask, the bomber's code.

dont forget the code in black and white 2 that depends on your country of your game

Answer 1

The only thing that comes to mind is your ID and your Secret ID that changes in each save file. Other than that, everything stays the same.

Hope I helped
