Code Help

[Okami5567]

I started using someone elses brawl hack alongside mine to somewhat mix and match and am finding our codes to be rather different... I much prefer theirs because mine causes about half of the available PSA's to freeze but theirs lacks the allows, shiek, ZS Samus, etc... So basically, how do I go about adding the code to add these?
