Lol..sorry i confused you...what you can do is get something called cupASH. its a program that opens up all of the image files in the common2.pac so you can edit them. however i think they come out as .TGA files and you have to use a program like photoshop
No, don't confuse him and make him use an effectively worthless program D:
Use BrawlBox and open up common5.pac. Go to sc_selcharacter_en inside of common5 and then go to char_bust_tex_lz77 and inside each of the MiscDatas is a different characters CSP's. Extract them in any image format you like, edit them and then replace them.
And if you have a sc_selcharacter.pac with all of the CSP's in it already you can just right click the sc_selcharacter_en inside of common5, click replace and then replace it with your file. Just make sure all of the MiscDatas inside of char_bust_tex_lz77 have their compression set to LZ77 (which you can check to see if it is on the right side of the window in BrawlBox).
