This one thing...

Hello there,

I just registered to ask about a feature of the ACCF tools I'm badly missing. I downloaded a save from another person and
in this save, the player set his birthday which appears to be different from mine. As you can't change the birthday of the player just like this,
I wanted to ask if it's possible to hack it. You can change practically everything with the tools, but this is the one little thing I'd like to have.

Could anyone consider to make a birthday changer or explain me how it might work?

Thank you very much for your answers!

Regards
