Can I limit the amount of Pokemon my trainer has to 3?

[bannabudder]

I'd like to make a Rom hack where everyone has 3 Pokemon. I can easily do this for trainers but I'm not sure for the main one. I'm new to this so any help would be appreciated. I'm thinking either place 3 eggs in his inventory, make them blacked out etc and unbreakable. Or code it in?

I don't think you can. But if you want it so much you can use pret. But I am not a master so ask it to some pro ones lik Jpan or SQ.
