Is there any way easier to change them? i tried it multiple times but i always fail

Hi, could someone teach me how to change the entry code of a character to a No Entry one?

I really want to use Sephiroth (Import-Model, PSA, Texture) by DivineOverlord and some other characters but i need to change the Entry code and i dont know how.

Sorry for noob questions

Tahnks, both of you, you really helped me

Thanks, i have the character and his movesets, but how do i get the character icon and the name to show in the battle menu? and do i need to do something more in Wiiscrubber or Brawlbox to replace the sounds/voices?

i want to import Shadow The Hedgehog (http://forums.kc-mm.com/Gallery/BrawlView.php?Number=2369&Moderated=All&facebook=true) to SSBB but i dont know how, please help
