Common5.pac working but Common_en, 3, and 4 isn't.

[KGN Nappdagg]

All files are in System/
They were named: Common5.pac Common3.pac Common4.pac Common.pac

tried them out, only css showed up.

Then since CSS Worked and Items, but nothing elses did, I changed to: Common_en, and Common4_en

still nothing. Particularly, the only things that aren't working are the character commons (Sheik, zss, bowser, kirby etc.) why do i need them to work? well for ABloodyCanadian's new Cinematic Final Smashes.
Additional elaboration: I used ASF1nk's Flaming Blue CSS for my own project, and in his thread, I downloaded the already set up codes, directory everything, so please help. Thanks.
